How this calculation works
This installment-loan model uses equal end-of-month payments and monthly interest. All payment periods must be whole months. Rate is the contract interest rate; APR can include fees. No daily accrual, balloon payment or variable rate.
Reference: method and limitations. Method reviewed October 22, 2026.
Check the assumptions
Use one currency consistently; financial outputs use that same currency, except the U.S. tax tool specifically uses USD. Financial models use your assumptions, not live rates or personalized financial advice. Check the result against your contract or the applicable tax rules.
