SIP Calculator — Future Value & Returns
Estimate SIP maturity value, total investment, and wealth gained — standard future-value math with step-by-step breakdown.
Formula: EMI = P × r × (1+r)^n / ((1+r)^n − 1) · 3 inputs · step-by-step working
EMI fixes your monthly repayment across the loan tenure. Early payments contribute more to interest; later ones reduce principal faster.
Enter loan amount, annual rate (percent), and tenure in years.
An Equated Monthly Instalment (EMI) is the same payment every month until the loan is repaid. Each EMI covers that month’s interest on the outstanding balance, and the rest reduces the principal. Because the balance is highest at the start, early EMIs are mostly interest; as the balance falls, more of each EMI goes to principal.
The calculator converts your annual rate to a monthly rate (annual rate ÷ 12 ÷ 100) and your tenure to months (years × 12), then applies EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1). It shows the number of months, the monthly rate, the EMI, total interest and total payable, followed by a year-by-year repayment schedule of principal repaid, interest paid and the balance left at the end of each year. For a month-by-month schedule, ask your bank.
Example: NPR 25,00,000 at 10% for 10 years. The monthly rate is 0.8333% over 120 months, giving an EMI of NPR 33,037.68. Total payable is NPR 39,64,522.11, of which NPR 14,64,522.11 is interest. In the first month, interest is NPR 20,833.33 (25,00,000 × 10 ÷ 1,200), so only about NPR 12,204 of that first EMI reduces the principal.
On the 20-year home loan, the interest alone is about 1.4 times the amount borrowed, so you repay roughly 2.4 times the principal in total. Personal loans are unsecured and usually carry a higher rate than home or vehicle loans, which is why a much smaller loan still costs close to NPR 2 lakh in interest over five years.
| Loan | Amount | Rate | Tenure | EMI | Total interest | Total payable |
|---|---|---|---|---|---|---|
| Home loan | NPR 50,00,000 | 10.5% | 20 years | NPR 49,919 | NPR 69,80,559 | NPR 1,19,80,559 |
| Motorcycle loan | NPR 3,00,000 | 12% | 3 years | NPR 9,964 | NPR 58,715 | NPR 3,58,715 |
| Personal loan | NPR 5,00,000 | 14% | 5 years | NPR 11,634 | NPR 1,98,048 | NPR 6,98,048 |
Rates are illustrative, not quotes. Figures are rounded to the nearest rupee.
Half a percentage point matters: moving from 10% to 10.5% on this loan adds about NPR 1,334 a month and about NPR 3.2 lakh of interest over 20 years. That is worth negotiating before you sign.
Tenure works the other way. Stretching from 20 to 25 years cuts the EMI by only about NPR 2,253 but adds about NPR 16.4 lakh of interest. Choosing 10 years instead of 20 raises the EMI by about NPR 14,259 but saves about NPR 29.2 lakh. Pick the shortest tenure whose EMI you can pay comfortably every month.
