Floating Vs Fixed Calculator — Calculations & Slabs for FY 2026-27

Compare the total interest cost of a fixed-rate loan against a floating-rate scenario over your tenure to see which saves more at different rate-change assumptions.

Frequently Asked Questions (FAQ)

What is the difference between fixed and floating interest rates?

A fixed interest rate remains constant throughout the entire loan tenure, providing predictable monthly payments. A floating interest rate fluctuates in response to market dynamics and changes in benchmark lending rates (like Repo Linked Lending Rate - RLLR) set by the RBI.

Under what market conditions should I choose a fixed interest rate?

A fixed interest rate is beneficial when lending rates are historically low and are expected to rise in the future. It offers peace of mind by protecting you from future EMI hikes, though lenders typically charge a premium (1% to 2% higher) over floating rates.

Can I switch from a fixed rate to a floating rate loan later?

Yes, most banks and housing finance companies allow you to switch from a fixed rate to a floating rate (or vice versa). However, you will need to pay a nominal conversion fee or processing fee, and check if foreclosure penalties apply.

What is the reset period in floating rate home loans?

The reset period is the interval at which your floating loan's interest rate is updated according to changes in benchmark lending rates. Depending on the loan agreement, reset periods are typically monthly, quarterly, or semi-annually. This ensures full compliance with the latest regulations, allowing you to estimate values correctly and avoid common filing errors.

What Does This Calculator Do?

This calculator compares the financial cost of a fixed interest rate loan versus a floating interest rate loan. It simulates different scenarios (interest rates rising, staying flat, or falling) to help you choose the most cost-effective borrowing option.

How to Use It

  1. Loan Amount (₹): Enter the total loan amount you intend to borrow.
  2. Fixed Rate (%): Enter the interest rate offered for a fixed-rate loan.
  3. Current Floating Rate (%): Enter the starting interest rate for the floating option.
  4. Expected Rate Change (%): Enter the rate fluctuation you want to simulate (e.g. 0.5% per year).
  5. Tenure (Years): Enter the repayment tenure of the loan.

The Logic Explained Simply

  • The Concept: Fixed rate loans provide certainty because your EMI remains the same throughout the tenure, but they usually charge a premium over floating rates. Floating rate loans fluctuate with market rates. If rates rise, your floating EMI or tenure increases; if rates fall, your loan costs decrease.
  • The Formula:
  • EMI = [P × r × (1 + r)^n] / [(1 + r)^n - 1]
  • Fixed Cost: Calculated using the fixed rate for all months.
  • Floating Cost: Calculated in three scenarios:
  • Scenario 1 (Base): Rate remains flat at the current floating rate.
  • Scenario 2 (Up): Rate increases by the expected change (simulated as an immediate or gradual rate increase).
  • Scenario 3 (Down): Rate decreases by the expected change.

Real-World Calculation Breakdown

Consider a loan of ₹50,00,000 for 20 years:

  • Fixed rate option = 9.5% -> Monthly EMI = ₹46,607. Total 20-year cost = ₹1,11,85,680
  • Floating rate option = 8.5% (starting rate):
  • Scenario 1 (Rate stays at 8.5%): EMI = ₹43,391. Total cost = ₹1,04,13,840
  • Scenario 2 (Rate rises to 9.0%): EMI = ₹44,986. Total cost = ₹1,07,96,640
  • Scenario 3 (Rate falls to 8.0%): EMI = ₹41,822. Total cost = ₹1,00,37,280
  • Comparing Fixed (₹1.11 Cr) vs Floating Base (₹1.04 Cr) shows you save ₹7.7 Lakhs if rates stay flat.
