EMI (Equated Monthly Instalment) is the fixed amount you pay monthly to repay a loan. In Nepal, most banks use the reducing-balance method.
What EMI includes
An EMI has two parts: interest on the outstanding balance and repayment of principal. In the early months, interest takes a larger share because the outstanding balance is high. As the loan is paid down, the interest portion falls and the principal portion rises. The EMI itself stays fixed under a standard reducing-balance loan, unless the rate changes or you make a prepayment.
This is why a loan can feel like it is barely moving in the first year. You are not doing anything wrong; that is how amortisation works.
EMI formula (reducing balance)
EMI = [P × r × (1+r)^n] / [(1+r)^n – 1]
Where:
- P = Principal loan amount
- r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
- n = Number of monthly installments
If rate is 0%, EMI = P/n.
Use the monthly rate, not the annual rate. For 10% annual, r = 10 ÷ 12 ÷ 100 = 0.008333. For 14%, r = 0.011667.
Example calculation
Example: Home loan of Rs 20,00,000 at 10% annual for 20 years (240 months)
- r = 10/12/100 = 0.008333…
- n = 240
- EMI ≈ Rs 19,300 (approximate; actual depends on bank rounding)
Total payment over 240 months is about Rs 46,32,000. Total interest is therefore roughly Rs 26,32,000 — more than the original loan. That number surprises many borrowers, which is why comparing total interest matters as much as comparing EMI.
Worked example: personal loan
Example: Personal loan of Rs 5,00,000 at 14% annual for 3 years (36 months)
- r = 14/12/100 = 0.011667
- n = 36
- EMI ≈ Rs 17,100
- Total payment ≈ Rs 6,15,600
- Total interest ≈ Rs 1,15,600
A personal loan is usually unsecured, so the rate is higher and the tenure shorter. The monthly burden is significant relative to the amount borrowed.
How tenure changes the numbers
Using the same Rs 20,00,000 home loan at 10%:
| Tenure | Approx. EMI | Total interest | Total payment |
|---|---|---|---|
| 10 years | Rs 26,400 | Rs 11,71,000 | Rs 31,71,000 |
| 15 years | Rs 21,500 | Rs 18,69,000 | Rs 38,69,000 |
| 20 years | Rs 19,300 | Rs 26,32,000 | Rs 46,32,000 |
A longer tenure lowers the monthly pressure but raises the total interest substantially. A shorter tenure does the opposite. The right choice depends on your cash flow and how much interest you are willing to pay for flexibility.
Calculate with our tool
Use the free Nepal EMI Calculator to:
- Get instant EMI
- See total interest and total payment
- View month-by-month amortization schedule
- Compare different tenures/rates
The amortisation schedule is the most useful part. It shows how much of each payment goes to interest and how the balance falls over time. Try one extra payment a year in the calculator to see the effect.
Factors to consider
| Factor | Impact |
|---|---|
| Interest rate | Higher rate = higher EMI and total interest |
| Tenure | Longer tenure = lower EMI, higher total interest |
| Processing fee | Upfront cost |
| Insurance | Often required, adds cost |
| Fixed vs floating | Floating rate can change over time |
| Prepayment | Can reduce interest significantly |
Fees beyond the interest rate
A low advertised rate can be less competitive once fees are included. Ask for the processing fee, valuation fee, legal fee, insurance premium, and any annual or renewal charges. Add these to the cost of borrowing and compare the effective cost, not just the headline rate.
Fixed vs floating
A fixed rate gives certainty but may start higher. A floating rate moves with the bank’s base rate, so your EMI or tenure can change. If you choose floating, stress-test the budget at two or three percentage points higher. If the higher payment would break your budget, the loan is too large.
Tips to save interest
- Choose shorter tenure if affordable
- Make prepayments when possible (bonus, extra income)
- Compare banks: Look at effective rate including fees
- Check prepayment charges: Some loans have fees
- Pay early: Early prepayments save more in reducing-balance loans
- Round up your EMI if the bank allows it
- Avoid extending tenure just to lower the monthly figure
Prepayments made early in the loan save more interest because the outstanding balance is still high. A prepayment in year two is worth much more than the same amount in year fifteen.
Home vs personal loan differences
- Home loan: Lower rates, longer tenure (up to 20+ years), often requires collateral
- Personal loan: Higher rates, shorter tenure (1-5 years), usually unsecured
- Home loan: Property valuation and insurance are part of the process
- Personal loan: Approval can be faster, but the rate reflects the lack of security
Do not use a short-term personal loan to cover a long-term asset purchase if a secured loan is available and affordable. The interest difference can be large.
Affordability check
A common guideline is to keep total EMIs below 40% of net monthly income, and preferably closer to 30-35% if you have variable income or dependants. Lenders may approve a higher ratio than is comfortable, so do your own budget.
Include rent, school fees, insurance, transport, and emergency savings before deciding what EMI you can carry. An emergency fund of at least three to six months of expenses makes a loan much safer.
Common mistakes
- Comparing only the EMI and ignoring total interest
- Forgetting processing fees, insurance, and valuation costs
- Assuming a quoted “flat rate” is the same as a reducing-balance rate
- Borrowing the maximum the bank offers rather than what the budget allows
- Not stress-testing a floating rate
- Failing to ask whether prepayment reduces tenure or EMI
Checklist before taking loan
- Calculate EMI and ensure affordable (ideally <40% of net income)
- Compare rates from multiple banks
- Check all fees (processing, insurance, valuation)
- Understand prepayment terms
- Read loan agreement carefully
- Confirm fixed or floating rate and the reset terms
- Keep an emergency fund after paying the down payment
Rates vary by bank and time. Use the calculator for estimation only.
