FAQ

Loan payment questions answered

What's the difference between interest rate and APR?+

Interest rate is the cost of borrowing principal. APR includes interest plus fees (origination, points, etc.). For accurate monthly payments, use the interest rate. For total loan cost comparison, use APR.

How does extra payment affect my loan?+

Extra payments go directly to principal, reducing future interest. Even $50/month can shave years off your mortgage and save tens of thousands in interest. Our tool shows exact impact.

Should I choose 15-year or 30-year mortgage?+

15-year has higher monthly payments but lower total interest. 30-year has lower payments but more interest. Use our comparison tool to see which fits your cash flow and long-term goals.

What is amortization?+

Amortization is the process of paying off a loan with regular payments. Early payments go mostly to interest; later payments go mostly to principal. Our schedule shows exact split each month.

Does this calculator work for existing loans?+

Yes — enter your current balance, remaining term, and interest rate. See payoff date and explore extra payment scenarios.

What's the formula for monthly payment?+

P = L × [r(1+r)^n] / [(1+r)^n - 1], where L = loan amount, r = monthly interest rate, n = total payments. Our calculator handles the math instantly.

How do I include property taxes and insurance?+

Toggle "Include Taxes & Insurance" in advanced options. Enter annual tax and insurance amounts — we'll add to monthly payment for full PITI estimate.

Is refinancing worth it?+

Use our refinance comparison tool. Enter current loan details and proposed new loan (rate, term, closing costs). We'll calculate monthly savings and breakeven months.
