FAQ
Frequently Asked Questions
How is the monthly payment calculated?
Monthly payment uses the standard amortization formula: P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. For interest-only loans, the payment is simply P × r.
What is an amortization schedule?
An amortization schedule is a month-by-month breakdown of each payment, showing how much goes toward reducing the principal balance versus paying interest, along with the remaining balance after each payment. Early payments are mostly interest; later payments are mostly principal.
Does it account for taxes and insurance?
No. The calculator computes principal and interest only. Property taxes, homeowner's insurance, PMI, and other escrow items must be added separately to determine your full monthly housing cost (PITI).
Can I use it for mortgages?
Yes. Enter your mortgage amount, annual interest rate, and loan term in years (e.g. 30 years). The calculator works for any fixed-rate loan — mortgages, auto loans, student loans, and personal loans alike.
