FAQ
Tap a question to expand.
Does total interest include fees?
No. This estimates contractual interest only. Processing fees, insurance, GST on fees, and penalties are excluded.
Does loan type change the interest math?
For standard EMI loans, no — longer tenure and higher rate mean more total interest. Enter your product’s actual rate and tenure whether personal, auto, home, or other.
Floating rate total interest?
Switch to floating, add rate resets, and interest is summed along that path. Compare with fixed at the start rate to see the impact of changes.
How do I model an education loan (simple interest during study, then EMI)?
During course / moratorium, many education loans use simple interest on the disbursed amount. Use the Simple Interest calculator for that phase. If interest is unpaid and added to the loan, new principal ≈ original principal + unpaid simple interest. Then use the EMI or amortization calculators on that outstanding for the repayment period.
Which loans can I use these calculators for?
Any standard reducing-balance EMI loan in ₹ — personal loan, home / housing loan, car / auto loan, two-wheeler loan, business loan, loan against property (LAP), gold loan (EMI stage), education loan once repayment has started, and similar products. Enter principal, annual rate, and tenure from your agreement. The math is the same; only your inputs change.
