Overview

About Mortgage Calculator


The QuickToolz Mortgage Calculator computes your monthly mortgage payment, total interest, and complete amortization schedule for any home loan. Enter the loan amount, annual interest rate, and term (typically 15, 20, or 30 years) and see exactly what you’ll pay each month and over the lifetime of the mortgage.

What the mortgage calculator shows

  • Monthly principal + interest payment

  • Total interest paid over the full term

  • Total cost of the home (principal + interest)

  • Amortization schedule — month-by-month split of principal vs interest

Plan smarter with scenarios

Compare a 15-year vs 30-year mortgage at the same rate to see how much interest you’d save with a shorter term. Try a 0.25% rate change to see lifetime cost impact. Model a larger down payment to lower the principal and monthly EMI.

FAQ

Frequently asked questions about Mortgage Calculator.

Got questions? We’ve got answers. Common questions about Mortgage Calculator.


M = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is loan amount, r is monthly rate, and n is number of monthly payments. Our calculator uses this standard formula.

No — it calculates principal and interest only (P&I). Property tax, homeowner’s insurance, and PMI vary by location and lender and should be added separately.

15-year mortgages have higher monthly payments but dramatically lower total interest. 30-year mortgages free up cash flow but cost more over time. Use the calculator to compare both at the same loan amount.
