 What are Amortization Schedules?

What Is a Loan Amortization Schedule?

A loan amortization schedule is a complete table of periodic loan payments, showing the principal amount and the amount of interest that comprises each payment until the loan is paid off at the end of its term. Each periodic payment is the same amount in total for each period.

However, early in the schedule, the majority of each payment is what is owed in interest because the initial outstanding loan balance, which is the basis for the interest calculation, is large; later in the schedule, the majority of each payment covers the loan’s principal because the outstanding loan balance becomes smaller over time as the payments continue to be made.


1.A loan amortization schedule is a table that shows each periodic loan payment that is owed, typically monthly, and how much of the payment is designated for the interest versus the principal.

2.Loan amortization tables can help a borrower keep track of what they owe and when payment is due and forecast the outstanding balance or interest at any point in the cycle.

3.Loan amortization schedules are often seen when dealing with installment loans that have known payoff dates when the loan is taken out, such as a mortgage or a car loan.

Understanding a Loan Amortization Schedule

In a loan amortization schedule, the percentage of each payment that goes toward interest diminishes, and the percentage that goes toward principal increases.1 Take, for example, a loan amortization schedule for a $250,000, 30-year fixed-rate mortgage with a 4.5% interest rate. The first few lines look like this:

If you are looking to take out a loan, besides using a loan amortization schedule, you can also use a mortgage calculator to estimate your total mortgage costs based on your specific loan.

Amortization schedules can be customized based on your loan and your circumstances. With more sophisticated amortization calculators, like the templates you can find in Excel, you can compare how making accelerated payments can accelerate your amortization. If, for example, you are expecting an inheritance or you get a set yearly bonus, you can use these tools to compare how applying that windfall to your debt can affect your loan’s maturity date and your interest cost over the life of the loan. You can do this with an auto loan, student loan, mortgage, Home Equity Loan, personal loan, or any other type of fixed-term loan.

As well as mortgages, car loans, and personal loans are also given for a term set in advance, at a fixed interest rate with a set monthly payment. The terms vary depending on the asset. Most conventional home loans are 15- or 30-year terms. Car owners often get an auto loan that will be repaid over five years or less. For personal loans, three years is a common term.

Formulas in a Loan Amortization Schedule

Borrowers and lenders use amortization schedules for installment loans that have payoff dates known when the loan is taken out, such as a mortgage or a car loan. There are specific formulas that are used to develop a loan amortization schedule. These formulas may be built into the software you are using, or you may need to set up your amortization schedule from scratch.

Suppose you know the loan term and the total periodic payment amount. In that case, there is an easy way to calculate a loan amortization schedule without resorting to an online amortization schedule or calculator. The formula to calculate the monthly principal due on an amortized loan is as follows:

Principal Payment = Total Monthly Payment – [Outstanding Loan Balance x (Interest Rate / 12 Months)]

To illustrate, imagine a loan has a 30-year term, a 4.5% interest rate, and a monthly payment of $1,266.71. Multiply the loan balance ($250,000) by the periodic interest rate starting in month one. The periodic interest rate is one-twelfth of 4.5% (or 0.00375), so the resulting equation is $250,000 x 0.00375 = $937.50. The result is the first month’s interest payment. Subtract that amount from the periodic payment ($1,266.71 – $937.50) to calculate the portion of the loan payment allocated to the principal of the loan’s balance ($329.21).


Amortization tables typically include a line for scheduled payments, interest expenses, and principal repayment. Suppose you create your amortization schedule and plan to make any additional principal payments. In that case, you will need to add an extra line for this item to account for additional changes to the loan’s outstanding balance.

What is an Easier way to Calculate a Loan Amortization Schedule?

Calculating a loan amortization schedule is as simple as entering the principal, interest rate, and loan term into a loan amortization calculator. But you can also calculate it by hand if you know the rate on loan, the principal amount borrowed, and the loan term.

How to calculate the total monthly payment

Typically, the total monthly payment is specified by your lender when you take out a loan. However, if you are attempting to estimate or compare monthly payments based on a given set of factors, such as loan amount and interest rate, you may need to calculate the monthly payment.

If you need to calculate the total monthly payment for any reason, the formula is as follows:

Total Monthly Payment = Loan Amount [ i (1+i) ^ n / ((1+i) ^ n) – 1) ]

i = monthly interest rate. You’ll need to divide your annual interest rate by 12. For example, if your annual interest rate is 6%, your monthly interest rate will be .005 (.06 annual interest rate / 12 months).

N = number of payments over the loan’s lifetime. Multiply the number of years in your loan term by 12. For example, a 30-year mortgage loan would have 360 payments (30 years x 12 months).

Using the same example from above, we will calculate the monthly payment on a $250,000 loan with a 30-year term and a 4.5% interest rate. The equation gives us $250,000 [(0.00375 (1.00375) ^ 360) / ((1.00375) ^ 360) – 1) ] = $1,266.71. The result is the total monthly payment due on the loan, including both principal and interest charges.

15-Year Amortization Table

If a borrower chooses a shorter amortization period for their mortgage—for example, 15 years—they will save considerably on interest over the life of the loan, and they will own the house sooner. They’ll make fewer payments for which interest will be amortized. Additionally, interest rates on shorter-term loans are often at a discount than longer-term loans.

There is a tradeoff, however. A shorter amortization window increases the monthly payment due on loan. Short amortization mortgages are good options for borrowers who can handle higher monthly payments without hardship; they still involve making 180 sequential payments (15 years x 12 months).

It’s important to consider whether or not you can maintain that level of payment based on your current income and budget. A 15-year amortization calculator can help you compare loan payments against potential interest savings for a longer amortization to decide which option suits you best. The same $250,000 loan example mentioned earlier looks like, with a 15-year amortization instead.

Important –

Refinancing from a 30-year loan to a 15-year mortgage could save you Money on interest charges but whether it does or not depends on how much of the original loan’s interest you’ve already paid off.

The Bottom Line

Understanding the loan amortization schedule on loan you are considering, or a loan you already have can help you see the big picture. By comparing the amortization schedules on multiple options, you can decide what loan terms are right for your situation, the total cost of a loan, and whether or not a loan is right for you. If you are trying to pay down debt, comparing the amortization schedules on your existing loans can help you determine where to focus your payments.

Why Am I Using the Amortization Schedule Software?

Amortization schedule software is a popular software used by the general public to calculate the monthly payments of a mortgage. It is also used for calculating the amortization period of any other loan, such as car loans, credit cards, etc.

The software calculates the interest rates and principal amount paid each month based on certain parameters like the borrower’s age, credit score, etc. It also estimates how much Money will be available in case of emergencies and other expenses that may arise during repayment. The software will also provide how much Money will be needed to pay off the loan in years or months.

The Amortization Schedule Software generates the amortization schedule for a loan.
