Monthly Payment Calculator

Use this calculator to estimate the monthly payment on a loan from the loan amount, annual interest rate, and term in months. It is useful for quick payment planning across personal loans, auto loans, and other fixed-payment debt.

What this calculator does

The monthly payment calculator estimates a fixed loan payment.

It uses:

• loan amount
• annual interest rate
• loan term in months
• amortized payment formula

The result shows estimated monthly payment, total interest, and total paid over the full term.

How to use the monthly payment calculator

Enter the loan amount, interest rate, and number of months. The calculator assumes a fixed rate and equal monthly payments.

For a fuller payment schedule, use the Amortization Calculator. For broader loan planning, use the Loan Payment Calculator.

Monthly Payment Formula

Monthly payment = P x [r(1+r)^n] / [(1+r)^n - 1]

Where P is loan amount, r is monthly interest rate, and n is total months.

Example calculation

If:

• Loan amount = 15,000
• Annual interest rate = 6%
• Term = 48 months
• Monthly rate = 0.5%

Then:

Monthly payment = 15,000 x [0.005(1.005)^48] / [(1.005)^48 - 1]

The estimated payment is about 352.28 per month.

What is a monthly payment?

A monthly payment is the regular amount paid each month toward a loan. For amortized loans, each payment includes interest and principal.

Early payments usually contain more interest, while later payments reduce more principal.

Interpreting your result

The payment helps with affordability, but total interest shows the full cost of the loan. A longer term can lower the payment while increasing interest.

When to use this calculator

Use this calculator when you want to:

• estimate loan payment
• compare repayment terms
• check affordability
• understand total interest

Common mistakes

Common mistakes include:

• using years instead of months
