Loan Prepayment Calculator
Home loan feeling heavy? See exactly what a one-time prepayment does. Two options side-by-side: finish faster, or pay less monthly.
A single lump payment towards principal
How much MORE than the scheduled EMI you can pay each month
Amortization schedule
See if refinancing beats prepaying at your current rate.
The main NetCorpus India planner rolls this into a 50-year retirement plan alongside your loans, EPF, taxes, trips, and life goals.
Shows exactly how much interest a lump-sum prepayment saves and how many months it shortens your loan by — since banks apply prepayments to principal first, and every rupee off principal stops earning interest immediately.
A prepayment reduces the outstanding principal on the date it's made; interest for every subsequent month is then calculated on that lower balance. Since the EMI itself typically stays fixed (unless you request re-amortization), the loan simply finishes earlier — the calculator recomputes the full remaining schedule with and without the prepayment to show the exact interest saved and months shaved off.
On a ₹40L loan at 8.5% with 15 years remaining, a ₹5L lump-sum prepayment plus an extra ₹5,000/month typically saves several lakh in interest and shortens the tenure by multiple years — the exact figures depend on when in the tenure the prepayment happens, since earlier prepayments compound the savings for longer.
Is it always better to prepay than invest the same amount?▾
Not automatically. Compare your loan's after-tax interest rate against your realistic after-tax investment return. A home loan at 8.5% with no interest deduction (new tax regime) is a guaranteed 8.5% 'return' from prepaying; an equity SIP at 12% pre-tax is roughly 10.4% after LTCG — a real but modest edge, not a guarantee.
Does prepaying always reduce my EMI?▾
Only if you ask the bank to re-amortize. By default, most banks keep your EMI the same and simply shorten the tenure — which saves more total interest than reducing the EMI would, since the loan closes sooner.
