Monthly EMI: ₹21,494
Total interest: ₹2,89,634
Total repayment: ₹12,89,634
Formula
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P = principal amount, r = monthly interest rate (annual rate / 12 / 100), n = tenure in months.
Example calculation
Loan ₹10,00,000 at 10.5% p.a. for 60 months: r = 0.00875, EMI = 10,00,000 × 0.00875 × 1.00875^60 / (1.00875^60 − 1) ≈ ₹21,494/month. Total interest ≈ ₹2,89,645.
Engineering notes
This calculator uses the reducing (diminishing) balance method, which is standard for most bank loans. For flat-rate EMI, the effective interest rate is roughly double the quoted flat rate. Always compare APR across lenders. For equipment financing in industrial projects, factor in GST on interest and processing fees.
When to use this calculator
- Equipment loan planning — calculate monthly outgo before purchasing machinery, compressors, or vehicles
- Project financing — model repayment schedules for plant construction or expansion loans
- Vendor credit terms — compare cost of credit from multiple lenders or NBFCs
- Budget forecasting — include EMI as a fixed cost line in project cost estimates
- Home loan comparison — compare two offers side-by-side by running the calculator twice
Frequently asked questions
- What is the reducing balance method for EMI?
- In the reducing balance (diminishing balance) method, interest is charged only on the outstanding principal each month. As you pay EMIs, the principal decreases, so the interest component falls each month while the principal repayment component rises. This is the standard method used by banks in India for home loans, vehicle loans, and equipment financing.
- How is EMI different from flat-rate interest?
- In a flat-rate loan, interest is calculated on the original principal for the entire tenure. In a reducing balance loan, interest is calculated on the remaining principal each month. For the same quoted rate, the flat-rate method is significantly more expensive — the effective annual rate is roughly double the flat rate. Always confirm the method your lender uses.
- Can I use this calculator for equipment or machinery loans?
- Yes. This calculator works for any amortised loan — home loans, vehicle loans, machinery loans, and industrial equipment financing. Enter the loan amount (principal), the annual interest rate quoted by your bank or NBFC, and the tenure in months. The result is your monthly EMI and total interest outgo for the full tenure.
- What happens to EMI if I make a prepayment?
- Prepayments reduce the outstanding principal. Lenders typically either reduce the tenure (keeping EMI the same) or reduce the EMI (keeping tenure the same). Re-run this calculator with the new outstanding principal and remaining months to estimate the revised EMI after a prepayment.
- How do I include this EMI in a project cost estimate?
- In industrial project costing, the annual EMI amount (monthly EMI × 12) is added under the "Machinery & Equipment" or "Finance Cost" section of the cost estimate. The Concept Industrial Suite costing platform includes an integrated EMI calculator in the equipment costing tab so you can directly embed the EMI liability into your project budget.
