Monthly Payment

Where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate, and n is the total number of payments.
M = P[r(1+r)^n] / [(1+r)^n - 1]

Variables:

MMonthly Payment
PPrincipal Loan Amount
rMonthly Interest Rate (Annual Rate / 12)
nTotal number of months

Example

  2. 2.Convert term to months: 5 * 12 = 60 months
  3. 3.Apply formula: M = 25000 * [0.005416(1.005416)^60] / [(1.005416)^60 - 1]
  4. 4.Calculate: M = $489.15

Frequently Asked Questions

Can I use this for an auto loan?

Yes, this payment calculator uses standard amortization math which works perfectly for auto loans, personal loans, and standard fixed-rate mortgages.

How does the loan term affect my payment?

A longer loan term will lower your monthly payment but increase the total amount of interest you pay over the life of the loan.
