NerdWallet’s installment loan calculator shows you a monthly installment loan payment, total interest costs and payoff date based on the loan amount, rate and repayment term you enter.

Unlike credit cards or credit lines, you borrow an installment loan in a lump sum and repay it over months or years. These loans have fixed interest rates, meaning the monthly payment won’t change during repayment.

Use this installment loan calculator to estimate your monthly payments and help you decide if an installment loan is the right choice for you.

How to use this calculator

1. Enter your loan amount (\$): Enter the amount you want to borrow, up to \$100,000. Borrowers with strong credit, high incomes and low debt have the best chances of qualifying for a larger loan.

2. Enter your interest rate (%): Enter the interest rate you expect to receive. Most installment lenders consider your credit and financial profiles, in addition to any collateral, when deciding your rate.

3. Choose a loan term (months): Decide how long you’ll want to repay the loan. A longer repayment term will have lower monthly payments but cost more in total interest, so find a term that keeps payments low without inflating interest costs too much.

4. Add a repayment start date (mm/yyyy): Enter the date you expect to make your first loan payment. Many lenders require the first payment on an installment loan 30 to 60 days after you receive the funds.

How installment loan rates and terms affect monthly payments

Your interest rate and loan term directly affect how much you pay toward your loan each month. Here’s how:

Interest rate: A higher interest rate means your monthly payments will be higher and you’ll pay more in total interest. Many personal loan lenders let you pre-qualify online to find the lowest rate without affecting your credit score.

Term: Your term also affects the loan’s total interest costs and monthly payment. A shorter-term loan will cost more each month, but you’ll save on interest charges.

Modify the rate and term in this calculator to see how the loan costs change.

Types of installment loans and how to calculate payments

Any loan you get in a lump sum and repay in equal bi-weekly or monthly payments is an installment loan. The following loans are all examples of installment loans.

Personal loans

Unsecured personal loans are from \$1,000 to \$100,000 and have rates from about 6% to 36%. Loan terms are usually two to seven years, and payments are often made in monthly installments. Most personal loans don’t require collateral to secure the loan. Instead, the lender uses your credit and financial information to decide whether you qualify.

Auto loans

Auto loans are usually for the cost of the vehicle you’re purchasing, minus your down payment. Rates are generally lower than personal loans and repayment terms can reach seven years, but NerdWallet recommends a term no longer than three years for used cars and five years for new cars. With an auto loan, the vehicle is collateral, meaning the lender can take the car if you miss payments.

Home equity loans

A home equity loan is a second mortgage with a fixed interest rate. Loan amounts are usually up to 85% of your home’s value minus what you owe on the first mortgage. Repayment terms are typically five to 20 years. Your home is collateral for a home equity loan, meaning the lender can take it if you don’t make payments.

“Buy now, pay later” companies offer low- or no-interest financing on purchases made in-store or online. These payment plans are structured as installment loans. The BNPL app effectively provides a small, short-term loan that you repay in four equal, bi-weekly payments, the first of which is due at the time of purchase.

High-interest installment loans

Some installment loans can have triple-digit interest rates, which makes them expensive and difficult to repay. These high-interest loans can be a few hundred dollars, but some lenders offer as much as \$10,000 or \$15,000. Repayment terms span from six months to five years.

High-interest lenders may not check your credit or review your income and expenses to determine whether you can repay the loan. Consider this type of loan a last resort when you’ve exhausted all other options.
