About this calculator

Overview

This Loan Prepayment Calculator estimates loan prepayment for loan or credit planning under the rates and tenure you enter (loans).

When to use

Use it to compare payment, interest, or balance scenarios before speaking with a lender. It is an estimate, not a sanction letter.

Inputs explained

  • Loan Amount (₹) [required]
  • Annual Interest Rate (%) [required]
  • Original Tenure (months) [required]
  • Prepayment Amount (₹) [required]
  • Prepayment Month (months) [required]

Formula / method

New Tenure calculated from reduced principal | Interest Saved = Original Interest - New Interest — Prepayment reduces outstanding principal, which reduces tenure and total interest (as implemented for `loan-prepayment-calculator`).

Worked example

Example: Prepay ₹5L on ₹30L loan at 8.5% for 20 years, prepay in month 12 (inputs principal = 3000000, annualRate = 8.5, tenureMonths = 240, prepaymentAmount = 500000; outputs tenureReduced = 36).

Interpreting results

Read loan prepayment together with total interest and tenure trade-offs. Small rate or tenure changes can move total cost more than monthly payment alone suggests.

Assumptions

  • Rate, fees, and payment frequency follow the values you enter.
  • No undocumented charges are added beyond the model on this page.
  • Cash-flow timing matches the calculator’s period convention (usually monthly).

Limitations

  • Lender amortization grids and rounding rules can differ from this estimate.
  • Floating-rate resets, insurance add-ons, and prepayment penalties are not fully modeled unless exposed as inputs.
