Quick guide
How to use this calculator
- Enter all amounts in one consistent currency.
- Use the rate and whole-period timing named by each visible label.
- Read the result together with its phase, fee, security, and contract exclusions.
Calculation method
Calculation method
Fee = principal × entered fee rate + fixed charge; net proceeds = principal − fee; financed balance alternative = principal + fee.
Entered monetary components use exact fixed-decimal arithmetic. Amortizing phases use the reviewed stable loan schedule and round only for presentation.
Worked example
Worked example
A 2% fee plus 100 on a 10,000 principal totals 300, leaving 9,700 if withheld or 10,300 if financed.
Fee = principal × entered fee rate + fixed charge; net proceeds = principal − fee; financed balance alternative = principal + fee.
Supported inputs

Estimate, not advice
The tools model only entered cash flows and contract components. They do not assess approval, legal enforceability, property value, future variable rates, or refinancing availability.
International scope
No currency, country, lender threshold, secured-credit law, tax treatment, fee rule, or consumer protection is assumed.
Calculator-specific assumptions
Withheld and financed results are alternative treatments. Confirm the contract treatment and do not add a charge already included elsewhere. This calculator does not produce an APR.
