Calculation method
Calculation method
Financed balance = principal + fee; payment uses the entered nominal annual rate divided by 12.
The calculator keeps full binary floating-point precision through the calculation and rounds only for display. It rejects non-amortizing payments, invalid rates, and schedules beyond the disclosed work limits.
Worked example
Practical example
Estimate the monthly cost of a 36-month equipment or working-capital loan.
Financed balance = principal + fee; payment uses the entered nominal annual rate divided by 12.

Precision and limits
Visible input limits

Estimate, not an offer
Results model only the values entered. Lenders may use different compounding, day counts, fees, payment allocation, or rounding.
International scope
No country, tax system, government benefit, regulated disclosure, or currency is assumed. Enter one consistent currency and verify local terms separately.
Calculator-specific assumptions
The fee is financed, payments are monthly, and the entered annual rate is divided by 12. Do not add fees already embedded in an effective disclosed rate.
