About Monthly Payment Calculator
The Monthly Payment Calculator answers one of the most common financial questions: "If I need to pay off a specific amount in N months, how much should I pay each month?" Enter the total amount, the number of months, and an optional interest rate to get your monthly payment.
Unlike the loan calculator which models a traditional amortizing loan, this tool is designed for simple payment plan scenarios — paying off a credit card balance, splitting a purchase into installments, or determining monthly contributions for a target total.

Troubleshooting
Entering a monthly interest rate instead of annual
Solution
Enter the annual interest rate (e.g., 18 for 18% APR). The calculator divides by 12 to get the monthly rate.
Confusing this with the loan calculator
Solution
The loan calculator models a new loan disbursed to you. This calculator is for paying off an existing total amount, such as clearing a balance or making installment payments on a purchase.
Setting too few months and getting an unexpectedly high payment
Solution
A shorter repayment period means higher monthly payments. If the monthly amount is too high, increase the number of months to find a more comfortable payment level.
Frequently Asked Questions
How is this different from the loan calculator?
The loan calculator models a new borrowing with standard amortization and shows a repayment schedule. This calculator focuses on paying off a fixed total over a specified number of months, with optional interest for financing scenarios.
What formula is used for interest-bearing plans?
The standard amortization formula is used: Payment = [Amount x r(1+r)^n] / [(1+r)^n - 1], where r is the monthly rate and n is the number of months.
Can I use this for a 0% interest payment plan?
Yes. Enter 0 as the interest rate and the monthly payment is simply the total amount divided by the number of months. Many retailer installment plans offer 0% financing.
How do I find out how many months it takes to pay off a debt?
Try different values in the months field while keeping the monthly payment in a range you can afford. Fewer months means higher payments but less total interest.
Does this show total interest paid?
Yes. When an interest rate is entered, the tool shows both the monthly payment and the total amount paid, letting you calculate the interest as the difference.
Can I plan credit card payoffs with this tool?
Yes. Enter your current balance as the total, your card's APR as the interest rate, and your desired payoff timeline in months. The monthly payment needed to achieve that goal will be displayed.
What if I want to pay off in one lump sum?
Enter 1 as the number of months. If there is an interest rate, one month of interest will be added to the total.
Is my data private?
Yes. All calculations run entirely in your browser. No financial data is transmitted or stored.
