About Amortization Calculator
The Amortization Calculator helps you understand how your loan payments are distributed between principal and interest over time. It generates a complete amortization schedule showing every payment's breakdown, helping you plan your finances better.
Our calculator uses the standard amortization formula to generate accurate schedules for any loan type - home loans, car loans, personal loans, or any other installment loan. You can also see the impact of extra payments on your total interest and loan tenure.
Understanding your amortization schedule helps you make informed decisions about prepayments, loan tenure, and interest rates. It's an essential tool for anyone with a long-term loan.

Amortization Formula
EMI = P × r × (1+r)^n / ((1+r)^n - 1)
Each month: Interest = Balance × r | Principal = EMI - Interest | New Balance = Balance - Principal
Amortization Example
| Month | EMI | Principal | Interest | Balance |
|---|---|---|---|---|
| 1 | $2,212 | $316 | $1,896 | $349,684 |
| 2 | $2,212 | $318 | $1,894 | $349,365 |
| 3 | $2,212 | $320 | $1,892 | $349,046 |
| ... | ... | ... | ... | ... |
| 240 | $44,986 | $44,653 | $333 | $0 |
* Example: $350,000 mortgage at 6.5% for 30 years (360 payments) — monthly payment $2,212
Impact of Extra Payments
| Extra Payment | Tenure Saved | Interest Saved | Total Savings |
|---|---|---|---|
| $0 | — | $0 | $0 |
| $100 | 3 years 6 months | $62,627 | $62,627 |
| $250 | 7 years 3 months | $126,604 | $126,604 |
| $500 | 11 years 5 months | $193,603 | $193,603 |
| $1,000 | 16 years 2 months | $265,954 | $265,954 |
* Based on a $350,000 mortgage at 6.5% for 30 years, with the extra amount paid every month
Tips for Using Amortization to Save Money
- 💡Make Extra Payments Early: Extra payments in the first few years save the most interest because interest is calculated on the outstanding balance.
- 💡Choose Shorter Tenure: While EMI is higher, total interest is significantly lower. Use the amortization schedule to see the difference.
- 💡Bi-Weekly Payments: Making half-payments every two weeks results in 13 full payments per year instead of 12, saving interest.
- 💡Refinance When Rates Drop: Even a 0.5% rate drop can save significant interest. Check your amortization schedule to see the impact.
- 💡Round Up Your EMI: Rounding up your EMI to the nearest hundred or thousand can shave months off your loan tenure.
Common Mistakes to Avoid When Using Amortization
- ⚠️Ignoring Extra Payment Impact: Even small extra payments can save thousands in interest. Always consider making extra payments when possible.
- ⚠️Not Understanding Early Payments: In early years, most of your payment goes toward interest. This is normal and part of the amortization process.
- ⚠️Overlooking Refinancing Opportunities: Regularly check if refinancing at lower rates can reduce your interest burden.
- ⚠️Choosing Longest Tenure: While it reduces EMI, it significantly increases total interest. Use amortization to see the difference.
- ⚠️Not Using Extra Payment Feature: Our calculator shows exactly how extra payments affect your loan. Use this to plan your prepayments effectively.
