Frequently Asked Questions

Q: What loan formula does the tool use?

The standard fixed-rate loan formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is principal, r is monthly rate, and n is number of payments.

Q: Does it account for variable interest rates?

No. This calculator is for fixed-rate loans. Variable rate loans require more complex modeling.

Q: Is my financial data sent to a server?

No. All calculations are done in your browser. Your financial information stays private.

Q: Can I use it for mortgages?

Yes. Enter the home loan amount, annual interest rate, and term (e.g. 30 years) to see monthly payments.

Q: Does the calculator include fees or insurance?

No. This calculator computes principal and interest only. Add any additional fees (origination, insurance) manually.
