Interest calculator

Calculate simple interest using annual, monthly or daily rates and multiple principal periods, with explicit date and year conventions.

Simple interest, without automatic compounding. Add a period when the rate or outstanding principal changes; periods must not overlap.

Period 1

Use the contract, judgment and enforcement determination for date conventions, year basis and remaining balances. Gaps accrue no interest; repayments are not allocated automatically.

Calculation result

Enter the parameters to see interest by period.

Monthly rates are annualized ×12 and prorated by actual days; this is not whole-month charging.
