Step-by-Step Instructions
Inspect Your Loan Amortization Schedule
Review your outstanding principal balance, current floating interest rate, remaining tenure in months, and current EMI amount from your bank statement.
Determine Your Annual Surplus Prepayment Capability
Assess how much extra annual cash flow (e.g., annual work bonuses, tax refunds, or savings surplus) you can dedicate to lump-sum prepayment.
Select Tenure Reduction vs. EMI Reduction Strategy
Input prepayment numbers into the Toolioz Loan Prepayment Calculator. Choose "Tenure Reduction" to maximize net interest compound savings.
Execute Partial Prepayment with Your Lenders
Submit partial prepayment instructions to your mortgage lender or bank, ensuring the payment is credited directly toward reducing outstanding principal.
The Mechanics of Amortization: Front-Loaded Interest Burden
During the first 5 to 10 years of a 20-year home loan, up to 70% to 80% of your monthly Equated Monthly Installment (EMI) goes toward paying interest charges, while only a small fraction pays down the principal balance.
Making a partial prepayment early in your loan tenure directly reduces the principal balance upon which future interest compound calculations are based, resulting in massive cumulative interest savings.
Tenure Reduction vs. EMI Reduction: Which Yields Higher Savings?
When you make a partial prepayment, banks offer two choices: keep tenure constant and lower your monthly EMI, or keep monthly EMI constant and shorten your loan tenure.
Choosing Tenure Reduction yields significantly higher interest savings. Keeping your EMI payment constant while principal shrinks accelerates compound interest savings, effectively cutting years off your mortgage.
Prepayment Penalties & Tax Deduction Realities
The prepayment calculator does not subtract a lender penalty and does not apply Section 24(b). Whether a bank charges a fee is not checked on the page.
The income-tax page and the prepayment page do not share inputs. A split between a loan payment and an investment is not calculated.

Frequently Asked Questions
Does the prepayment calculator choose an early lump sum?
No. It adds the same extra amount every month from the first month and keeps the EMI. A later lump sum is not compared.
Does the prepayment calculator report a credit score?
No. It reports interest saved and months removed. A credit-score change is not calculated.
