Calculate monthly repayments, total interest and full amortization. Works for US, UK, Australia, Canada and India.
Select your country to load the correct currency and local defaults, then enter your home price, down payment, loan term and interest rate. The calculator instantly shows your monthly principal and interest repayment, total interest paid over the life of the loan, and a full year-by-year amortization breakdown.
Monthly repayments use the standard amortization formula: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] — P = principal loan amount, r = monthly interest rate (annual ÷ 12), n = total number of payments (years × 12).
United States: The 30-year fixed-rate mortgage covers 70–90% of US home loans. FHA loans allow 3.5% down. PMI is required below 20% down. Current 30-year average rate: ~6.16% (April 2026).
United Kingdom: Most UK mortgages are 25-year repayment loans with a 2–5 year fixed period before reverting to SVR. First-time buyers are exempt from Stamp Duty on homes up to £500,000 (from April 2025).
Australia: 30-year terms are standard. Variable rates most common. A 20% deposit avoids Lenders Mortgage Insurance (LMI). The RBA cash rate directly influences mortgage rates.
Canada: Maximum amortization is 25 years for insured mortgages. The mortgage stress test requires qualifying at 2% above your contract rate. 5-year fixed rates are most popular.
India: Home loans typically run 20–30 years at floating rates linked to the RBI Repo Rate. Banks finance 75–90% of property value. Monthly repayments are called EMI (Equated Monthly Instalment).
On a $400,000 loan at 6.5%, a 30-year mortgage costs approximately $511,000 in total interest. A 15-year mortgage costs around $221,000 — a saving of $290,000. However your monthly payment is roughly 44% higher on the 15-year term. Use the calculator to model both scenarios for your exact numbers.
Amortization describes how a fixed-rate loan is paid off through equal regular payments over time. In early years, most of each payment goes toward interest. Over time, more goes toward principal. The table in this calculator shows the exact year-by-year split from start to payoff.
