How to use this calculator
Each step names a control you will find on screen above.
- Loan amount, Interest rate and Tenure
The basic terms. Note how much total interest changes when you move tenure by five years — far more than most people expect.
- Read the early-years split
In the first years almost all of the EMI is interest and almost none is principal. This front-loading is why early prepayment is so much more powerful than late.
- Extra every month
Add a small regular amount and watch the tenure collapse. Every extra rupee goes entirely to principal.
- One-off prepayment and Made in year
A lumpsum, and when it lands. Move the same amount from year 12 to year 3 and compare the interest saved.
Worked example: ₹5,000 a month that removes four and a half years
A ₹50 lakh home loan at 8.5% over 20 years. You add ₹5,000 a month from the start.
