The Basics of Loans: What You Need to Know

Loans are the financial instruments people use to borrow money. Whether they are getting a mortgage to buy a house, borrowing money to buy a car (as opposed to leasing or paying cash as discussed in this post), or other large purchase, not paying off their credit card in full or borrowing money from a friend, they are taking out a loan. In this post, I will cover the basics of loans, including:
- an introduction to the key terms
- a description of how loans work
- the factors that determine your monthly payment
- some common borrowing mistakes
In other posts, I talked about the pros and cons of pre-paying your student loans; more quickly.
The Basics of Loans: Key Terms
There are four basic terms common to almost all loans. They are:
- Down paymentThe amount you have to pay in cash up front for your purchase More – The amount you have to pay in cash up front for your purchase. For large purchases, such as homes, condos and vehicles, the lender requires that you pay for part of the purchase immediately. This amount is the down paymentThe amount you have to pay in cash up front for your purchase More. The lender wants you to have a financial interestA charge for borrowing money, most often based on a percentage of the amount owed. More in maintaining your purchase so it doesn’t lose value (as in the case of a residence) or lose value more quickly than expected (as in the case of a car). For some other types of loans, no down paymentThe amount you have to pay in cash up front for your purchase More is needed. Examples of such loans are student loans, credit card balances and personal lines of credit.
- PrincipalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More – The amount you borrow. - Interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More – The percentage that is multiplied by the portion of the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More you haven’t repaid yet to determine the amount of interestA charge for borrowing money, most often based on a percentage of the amount owed. More you owe. InterestA charge for borrowing money, most often based on a percentage of the amount owed. More rates are usually stated as annual percentages. They are divided by 12 to determine the interestA charge for borrowing money, most often based on a percentage of the amount owed. More that is due each month. - TermThe time period over which you re-pay the loan More – The time period over which you re-pay the loan.
The Basics of Loans: How They Work
How the Money Moves
When you borrow money, the lender usually pays a third party on your behalf. For example, when you buy a home or use a credit card, the lender gives the money directly to the seller or its escrow agent. For some loans, the lender gives the money to you, such as with a line of credit. The amount of money the lender gives you or pays on your behalf is the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More.
You then re-pay the loan by paying the lender periodically (usually monthly or bi-weekly). For most loans, you start making payments immediately. For some loans, though, such as student loans and some car loans, you don’t have to make payments right away. Most student loans don’t require any re-payments until after graduation. When entering into a loan that doesn’t require immediate payments, it is critical to understand whether interestA charge for borrowing money, most often based on a percentage of the amount owed. More will be adding up between the time you enter into the loan and the time you start making payments. Several years of interestA charge for borrowing money, most often based on a percentage of the amount owed. More, even at a low rate, can increase the amount you need to re-pay substantially.
Payments Include PrincipalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More and InterestA charge for borrowing money, most often based on a percentage of the amount owed. More
Part of each payment is the interestA charge for borrowing money, most often based on a percentage of the amount owed. More the lender charges you for letting you use its money. The rest covers repayment of the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More. For example, if you borrowed $20,000 (the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More) at 5% (the interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More) and started making monthly payment right away, the lender would calculate the interestA charge for borrowing money, most often based on a percentage of the amount owed. More portion of your first payment as 5% divided by 12 (months) times $20,000 or $83.33. Your monthly payment also includes some principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More. If you have a 10-year termThe time period over which you re-pay the loan More on this loan, your monthly payment will be $212.13. In this case, you will re-pay $128.80 ($212.13 – $83.33) of principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More in the first month.
In the second month, you’ll pay interestA charge for borrowing money, most often based on a percentage of the amount owed. More on $19,871.20 which is the original $20,000 you borrowed minus the $128.80 of principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More you paid in the first month. Your interestA charge for borrowing money, most often based on a percentage of the amount owed. More payment will be $82.80 and your principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More payment will be $129.33. Every month, you will pay more principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More and less interestA charge for borrowing money, most often based on a percentage of the amount owed. More. The chart below shows the mix of interestA charge for borrowing money, most often based on a percentage of the amount owed. More and principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More in each of the 120 payments of your 10-year loan.
Factors that Determine Your Monthly Payment
The monthly payment on a loan is a function of three numbers:
- Interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More – the higher the rate, the higher your monthly payment.
- PrincipalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More – the more you borrow, the higher your monthly payment. - TermThe time period over which you re-pay the loan More – the longer the termThe time period over which you re-pay the loan More, the less your monthly payment.
Sensitivity to Interest RateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More and TermThe time period over which you re-pay the loan More

The Math behind Your Monthly Payment
In this section, I’ll briefly explain the math that determines your monthly payment and will provide a bit of information about the Excel formulas you can use. Feel free to skip to the next section on common borrowing mistakes if you aren’t interested in this aspect of loans!
Present Values
The fundamental concept underlying the determination of the monthly payment on a loan is that the sum of the present values at the loan interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t...

Solving for Your Monthly Payment
This amount is set equal to the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More. The monthly payment can be calculated using a financial calculator, such as in Excel, or mathematically. The Excel formula is pmt(i/12, t, X). It will give you the negative of your monthly payment. ipmt and ppmt return the portion of each payment that is interestA charge for borrowing money, most often based on a percentage of the amount owed. More and principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More, respectively. In month y, the interestA charge for borrowing money, most often based on a percentage of the amount owed. More is ipmt(i/12, y, t, X).
For those of you who really like math, you can also calculate the monthly payment directly. If payments were made forever (an infinite series), the sum above would equal X/i. We need to eliminate the infinite series of payments after the end of the loan to determine the present valueThe value today of a stated amount of money you receive in the future. It is calculated by dividing the stated amount of money by 1 + the interest rate adjusted for the length of time, t, between th... More of the loan payments.

That is a bit of a messy formula, but, having gotten rid of the big sum, it can be solved using a fairly basic calculator.
Common Borrowing Mistakes
Some people end up in difficult financial situations, in bankruptcy or even homeless due to poor borrowing decisions. A few of the more common mistakes are identified below.
Not Understanding the Terms
Many mistakes result from not reading or not understanding the loan agreement. For example, some loans (mortgages in particular) have teaser rates or adjustable interestA charge for borrowing money, most often based on a percentage of the amount owed. More rates. If the interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More goes up on your existing loan at some point in the future, your payments will also go up. If you have an adjustable interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More on a loan, you want to make sure you’ll be able to afford higher payments if interestA charge for borrowing money, most often based on a percentage of the amount owed. More rates increase.
Another example of a loan provision that can be problematic is a balloon payment. Under some loans, the monthly payment is calculated as if the loan has a long termThe time period over which you re-pay the loan More, such as 15 or 30 years. However, after a shorter period of time, say 5 or 10 years, the remainder of the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More must be re-paid and the loan terminates. If you haven’t built up enough cash to re-pay the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More or can’t get another loan at a rate you can afford, you might default on your loan.
High Cost of Ownership
Many things that people buy with a loan come with other costs that they haven’t considered and might not be able to afford. For example, when you buy a car, you not only have to make your car payments, but also will need to pay for insurance (including physical damage coverageAn insurance coverage that protects you when you cause damage to your own property, such as in a car accident, or without human cause, such as fire, hail, storm or earthquake. More at a fairly low deductibleThe amount that you pay before the insurer starts reimbursing you either in part (see coinsurance) or in full. Deductibles can apply per claim (as is usually the case for auto collision and homeowners... More if required by the lender), gas and maintenance. Similarly, while you may be able to fit your mortgage payment in your budgetA plan showing targets for income and expenses over a fixed time period, such as a month or a year. More, you also need to be able to afford the costs of utilities, homeowners insurance and maintenance. In some cases, these additional costs lead to financial difficulties.
Mistakes that Increase Monthly Payments
Some mistakes cause people to have higher payments than necessary. For example, if you take out a personal loan from a bank, you often have the option to post collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More. If you do so, your interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More is likely to be lower, possibly by as much as 50%.
Another way people end up with monthly payments that are higher than they need to be is to take out a loan that is bigger than necessary. For example, if you can afford to make a larger down paymentThe amount you have to pay in cash up front for your purchase More than you actually make, the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More on your loan will be higher which increases your monthly payment. Many loans have pre-payment penalties which make it cost-prohibitive to pre-pay your principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More to bring it back in line with the amount you should have borrowed in the first place. Also, if the lower down paymentThe amount you have to pay in cash up front for your purchase More increases the ratio of the principalThe amount of money you borrowed or deposited, excluding any accumulated interest. Some examples include:
• Credit cards: The amount of purchases you have made but not paid on your credit card ... More to the value of your home by too much, it will also increase your interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More which further increases your payment.
Overestimating the Value of Your CollateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More
Another problem people encounter is an inability to borrow as much as they need because they overvalue their collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More. Common issues that arise include:
- Lenders get their own appraisals of houses. The lender’s appraisal is often lower than the purchase price and sometimes even lower than the assessed value. If the appraisal is less than the purchase price, the buyer must increase his or her down paymentThe amount you have to pay in cash up front for your purchase More so the ratio of the loan to the appraised value is within the lender’s limits. Even worse, some banks won’t issue the mortgage at all if the difference between the appraisal and the purchase price is too big, even if you increase your down paymentThe amount you have to pay in cash up front for your purchase More. In those situations, you need to either find another lender or re-negotiate your purchase price.
- Lenders use the National Auto Dealers Association (NADA) Guides to value used cars. These values can be different from Kelley Blue Book. In particular, the NADA Guides adjust the value based on the specific location of the vehicle. Also, the values in the NADA guides assume that the vehicle is in pristine condition for its age. If it has had any heavy use at all, the lender will reduce the value before determining the value of the collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More.
- For used cars, washed titles are also a problem. When a car has been severely damaged, its title is changed from the more typical “clean” title to a salvage title. However, when a car’s title is transferred from state to state, its damage history can get sometimes get lost as some states do not require salvage titles. However, other sources, such as CARFAX, maintain the information about the damage. Lenders will check these other sources before determining the value of the collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More.
While collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More helps reduce the interest rateThe percentage which, when multiplied by the face amount or principal of a financial instrument, such as a bond, savings account or loan, determines the amount of interest that will be paid to or by t... More on your loan, it is important to consider these points in determining the value of your collateralA physical asset pledged by a borrower as security to a lender for a loan. If the borrower defaults on the loan, the lender can take possession of the collateral. More.
Poor Uses of Debt
There are many things for which loans can be used, some of which are valuable and some of which are less so. This post provides a discussion of the characteristics that can help you identify which loans might be good for you.
