Periodic Reducing Balance Method

Interest is calculated on the outstanding principal balance each period. As you repay:

The principal reduces with each payment
The interest charged per period reduces accordingly
A greater share of each repayment goes toward principal over time

Interest is calculated per payment period — not daily

The annual rate is divided by the number of periods per year (i = rate ÷ frequency). Interest accrues once per period on the outstanding balance, whether that's weekly, fortnightly, monthly, or annually.

The Formula

M = P × [i(1+i)ⁿ] / [(1+i)ⁿ − 1]
i = annual rate ÷ periods per year
n = (term in months ÷ 12) × periods per year

Beyond the Standard Calculator.

Most online calculators are built to sell you a specific loan. Our tool is built for transparency. It uses an "open variable" logic, allowing you to work backward or forward.

Solve for Anything

Input any three loan values to find the fourth. Use it to determine your total loan capacity, required interest rate, or exact time to payoff based on your current data.

Independent Logic

Enter any interest rate from any source. We provide the raw data so you can compare offers fairly.
