About this calculator

Estimate the monthly payment and total cost of a loan from the amount borrowed, annual rate and term. EMI means equated monthly installment, the scheduled payment before any extra payments.

Compare reducing-balance interest with a flat finance charge, then see how monthly overpayments or a one-time payment change the repayment schedule.

How to use this calculator

  1. Choose one currency and enter the amount borrowed, annual interest rate and loan term in months.
  2. Select reducing or flat interest to match the loan calculation you want to model.
  3. Enter any extra monthly payment, one-time payment and its month, plus an upfront origination fee.
  4. Calculate, then compare the scheduled payment, total interest, payoff month and downloadable schedule.

Understand your result

The headline payment excludes extra payments. The schedule includes them and may finish with a smaller final payment. Total paid includes the upfront origination fee.

Interest saved compares the selected interest method with the same loan without extra payments. Flat finance charges remain payable in full in this model, even if the balance is cleared early.

Questions about this calculator

What is the difference between flat and reducing interest?

Reducing interest is charged on the outstanding principal each month. Flat interest is calculated from the original principal for the whole term. The same quoted percentage therefore does not produce the same cost.

Does an extra payment reduce my scheduled monthly payment?

The calculator keeps the scheduled payment and uses extra payments to clear the balance sooner. It does not model a lender recalculating the installment after an overpayment.

Are loan fees and early-settlement rebates included?

The entered origination fee is paid upfront and included in total paid. No early-settlement rebate is assumed for a flat loan, and other charges are excluded unless represented by an available input.

Formula and assumptions

Reducing payment = P r / (1 - (1+r)^(-n)); flat finance charge = P APR n / 12.

  • APR is nominal and divided by 12 for reducing-balance interest.
  • Payments occur at month end; interest is retained at full precision until display.
  • Flat finance charges are owed in full with no early-settlement rebate; each payment allocates the original principal-to-charge ratio.
  • The origination fee is paid upfront and is not financed.
