Mortgage Refinance Savings Calculator

Calculate monthly EMI savings and total interest saved by refinancing home loan.

Overview

Calculates monthly EMI savings, total interest saved, and break-even timelines when transferring a home loan to a lower interest rate lender.

Formula & Calculation Method

Monthly Savings = Old EMI - New EMI | Break-Even Months = Refinancing Costs / Monthly Savings

Accounts for processing fees, valuation charges, legal stamp fees, and foreclosure terms against cumulative interest savings.

Worked Example: Refinancing ₹35 Lakh Loan from 9.25% to 8.40% with 18 Years Left

Inputs: Loan Balance = ₹35,00,000 | Current Rate = 9.25% | New Rate = 8.40% | Remaining Term = 216 Months | Switching Cost = ₹18,000

  • Current Monthly EMI at 9.25% = ₹33,745 per month
  • New Monthly EMI at 8.40% = ₹31,880 per month
  • Monthly cash savings = ₹33,745 - ₹31,880 = ₹1,865 per month
  • Break-even timeline on ₹18,000 fees = ₹18,000 / ₹1,865 = 9.6 months

Summary: Monthly Savings = ₹1,865/mo | Lifetime Interest Saved = ₹3,84,840 | Break-Even Period = 10 Months

Common Use Cases

  • Home Loan Balance Transfer: Determine if moving a loan to another commercial bank offsets switching processing charges.
  • Tenure Reset Negotiation: Use competitive refinance quotes to negotiate an internal rate reduction with your existing lender.
  • Cash-Out Refinancing: Evaluate equity cash-out options to fund major home renovations.

Frequently Asked Questions

Can I reduce my interest rate without switching banks?

Yes, most banks offer an internal rate conversion (switching from an old benchmark to current RBLR) for a small processing fee (₹1,000 to ₹5,000).

What is MODT in home loan balance transfer?

Memorandum of Deposit of Title Deed: a statutory stamp duty (0.1% to 0.5%) charged by state governments when registering mortgages.

When is refinancing not recommended?

If you plan to sell the property or close the loan within 1-2 years, switching fees will outweigh interest savings.
