About This Calculator
A mortgage amortization schedule shows every monthly payment over the life of your loan, breaking each payment into the portion that goes toward interest and the portion that reduces your principal balance. This mortgage amortization calculator helps homeowners, homebuyers, and real estate investors understand how their monthly payments are applied and how the loan balance decreases over time.
The calculator uses the standard amortization formula: monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. The schedule then tracks each payment's interest and principal components along with the remaining balance after each month.
Regional Notes
India: Home loans typically range from 10 to 30 years with monthly reducing balance. Interest rates can be fixed or floating (linked to RBI repo rate). Many Indian banks offer home loans up to 80-90% of property value. Principal repayments on home loans qualify for tax deduction under Section 80C (up to ₹1.5 lakh) and interest payments under Section 24(b) (up to ₹2 lakh for self-occupied property).
United States: The 30-year fixed-rate mortgage is the most common, with 15-year terms also popular. Mortgage interest is tax-deductible for itemized deductions on loans up to $750,000. Many US mortgages include escrow for property taxes and homeowners insurance. PMI (Private Mortgage Insurance) is required when down payment is less than 20%.
United Kingdom: Repayment mortgages with 25-year terms are standard. Fixed-rate deals typically last 2-5 years before reverting to a standard variable rate (SVR). UK borrowers can use ISAs to save for a deposit. Stamp duty applies to property purchases above £250,000 (first-time buyers have relief up to £425,000).
Frequently Asked Questions
What is a mortgage amortization schedule?
A mortgage amortization schedule is a detailed table showing each monthly payment broken down into principal and interest portions, along with the remaining loan balance after each payment. It helps you understand how your loan is paid down over time, with more interest paid in early years and more principal paid in later years.
How is the monthly mortgage payment calculated?
The monthly payment is calculated using the standard amortization formula: EMI = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments. This ensures each payment is equal throughout the loan term.

Can I see the amortization schedule for my entire loan term?
Yes, the calculator shows the first 12 months of the amortization schedule in a detailed breakdown table. The interactive charts display yearly trends for the full loan term, including the remaining balance over time and the principal vs interest breakdown for each year.
How does mortgage amortization work in India, the US, and the UK?
In India, home loans typically use monthly reducing balance with floating or fixed rates over 10-30 years. In the US, 30-year fixed-rate mortgages are common with monthly payments, and interest may be tax-deductible. In the UK, repayment mortgages with 25-year terms are standard, and lenders use monthly or annual interest calculations. This calculator supports all regions with appropriate currency symbols and number formatting.
Why does more interest go to the lender in the early years?
In an amortized loan, interest is calculated on the outstanding principal balance. Early in the loan term, the principal balance is highest, so the interest portion of each payment is larger. As you make payments, the principal decreases, so less interest accrues and more of your payment goes toward reducing the principal.
What is the difference between EMI and amortization?
EMI (Equated Monthly Installment) is the fixed monthly payment you make. Amortization is the process of spreading out the loan into equal payments over time, where each payment covers both interest and principal. The amortization schedule shows how each EMI is split between interest and principal over the entire loan term.
