Loan Calculator FAQ

Enter your loan amount, interest rate, and loan term in years or months. The calculator uses the standard loan payment formula to compute your monthly payment, total interest, and amortization schedule.

Mortgages are secured by real estate (typically 15-30 years), auto loans are secured by vehicles (3-7 years), and personal loans are unsecured (2-7 years). Interest rates and terms vary by loan type and creditworthiness.

An amortization schedule shows how each payment is split between principal and interest, and how your loan balance decreases over time. Early payments are mostly interest; later payments are mostly principal.

Yes, extra principal payments reduce your loan balance and total interest paid. The calculator shows the impact of your regular payments, but you can manually calculate scenarios with additional payments.

Rates vary by credit score, loan type, and market conditions. Mortgages typically range from 3-7%, auto loans from 4-10%, and personal loans from 6-36%. Always shop around for the best rates.

The calculations use standard financial formulas and are mathematically accurate. However, actual loan terms may include additional fees, taxes, insurance, and variable rates that aren't included in basic calculations.
