Personal Loan Calculator

A personal loan calculator helps you understand how much you’ll pay for a personal loan over time, given certain conditions. If you’re unsure about the numbers, a calculator is an excellent tool for figuring out how certain variables like loan amount, estimated interest rate and loan term affect the overall cost of a personal loan.

Let’s explore common personal loan calculator parameters, how these calculators work and how they may help you find a personal loan.  

Understanding personal loan calculator parameters

Personal loan calculators typically use 3 key parameters: loan amount, estimated interest rate and loan term. These variables combine to calculate your specific estimated personal loan payment.

1. Personal loan amount

This section is where you enter your loan amount. Some personal loan calculators have a default number, which could serve as a good starting point if you're unsure exactly how much you need to borrow. However, be sure to input whatever loan amount you're looking for if you're certain.

2. Personal loan interest rate

In this field, you input whatever interest rate you estimate the loan will have. If possible, try to enter your expected annual percentage rate (APR), which accounts for your interest rate and fees. The APR may better determine your total loan cost than the interest rate alone.

3. Personal loan term

The loan term field lets you choose the duration of time the lender will give you to repay the loan. A longer term tends to mean lower monthly payments but may lead to more interest and a higher overall loan cost. A shorter term may lead to higher monthly payments but can offer savings on interest, compared to a loan with a longer term.

How do you calculate a personal loan payment?

After you input all the numbers, a personal loan calculator may display a monthly payment amount, the total interest paid, and the overall repayment needed.

Let’s say, say you need a $20,000 loan, and your estimated APR is 12%. Here’s what you would pay with a 3-year repayment term compared to a 5-year term:

Monthly loan payment calculator: 3-year term

Loan Amount $20,000
Loan Term (years) 3
APR 12%
Total Interest Paid $3,914.30
Total Repayment $23,914.30
Monthly Payment $664.29


With this plan, you would pay $23,914.30 on a $20,000 loan. Your monthly payment estimate would be approximately $664, and you would pay $3,914.30 in interest over the life of the loan.

Monthly loan payment calculator: 5-year term

Loan Amount $20,000
Loan Term (yrs) 5
APR 12%
Total Interest Paid $6,693.34
Total Repayment $26,693.34
Monthly Payment $444.89

With this plan, you would pay $26,693.34 on a $20,000 loan. Your monthly payment estimate would reduce to approximately $445, but you would pay more in interest, totaling $6,693.34, by the end of the loan term.

After your personal loan calculation

After calculating your personal loan payment and understanding your desired terms, it's time to find a personal loan. You can apply for a personal loan with traditional banks, online lenders or credit unions. Once you pick a lender, you typically need to provide basic information like your name, address and Social Security number, as well as documents showing your income. If you’re approved, the amount of time it takes to get your funds can vary by lender.
