MCLR vs EBLR vs Base Rate — which is your loan on?
If your rate barely moves when the RBI cuts, your loan is probably on an old benchmark. Here is how MCLR, EBLR and base rate differ — and how to stop overpaying.
If your home loan was sanctioned several years ago and your interest rate barely moves when the RBI cuts rates, the reason is almost certainly the benchmark your loan is linked to. Indian home loans have been priced against three different systems over the years, and the one you are on decides how quickly — or whether — you benefit when rates fall. This is one of the most consequential things to know about your loan, and most borrowers have never checked.
The three benchmarks, in order of age
Base Rate (2010–2016). The oldest system still in use. Each bank set its own base rate and could not lend below it. Base rates are slow to move and banks had little pressure to cut them, so loans stuck here are often the most overpriced today.
MCLR — Marginal Cost of Funds based Lending Rate (2016–2019). An improvement that tied lending rates to a bank's actual cost of funds. But MCLR loans reset only periodically (every 6 or 12 months), and the bank's internal cost calculation gives it room to pass on cuts slowly. When the RBI drops the repo rate, an MCLR borrower may wait two or three quarters to see any benefit — if at all.
EBLR / RLLR — External Benchmark / Repo-Linked Lending Rate (2019 onward). Since October 2019, the RBI has required banks to link new floating-rate retail loans to an external benchmark, almost always the repo rate. Your rate is simply the repo rate plus a fixed spread. When the RBI moves the repo rate, your rate moves with it, usually within the same quarter. This is the transparent, fast-passing system.
Why the difference matters in rupees
The repo rate today is around 5.25%. A modern EBLR home loan for a salaried borrower with good credit typically sits at roughly repo + 2.25% to 3.5%, putting it in the high-7s to high-8s. A loan still on MCLR or base rate from years ago can easily be running 1% or more above that — not because the borrower did anything wrong, but because the old benchmark never passed on the cuts.
On a ₹40,00,000 outstanding balance with 18 years left, paying 1% more than necessary costs several lakhs over the remaining tenure. That is the price of an outdated benchmark.
How to find out which one you are on
Check your loan sanction letter or your most recent statement — it will name the benchmark (Base Rate, MCLR, or EBLR/RLLR). If you cannot find it, ask your bank directly. As a rough guide: loans before 2016 are likely base rate, 2016–2019 likely MCLR, and 2019-onward likely EBLR. Our balance-transfer calculator includes a benchmark selector that diagnoses the gap for you.
What to do if you are on an old benchmark
You have two routes, and you should try them in order.
First, ask your existing bank to switch you to EBLR. Banks are permitted to move you from MCLR or base rate to a repo-linked rate, usually for a small conversion fee. This is the cheapest fix — no new paperwork, no new lender — and often closes most of the gap instantly.
Second, if your bank will not offer a competitive EBLR rate, transfer the loan. A balance transfer to a lender offering a genuine repo-linked rate can save lakhs, and because RBI bars foreclosure charges on floating-rate home loans, leaving costs only the new lender's processing fee. Use the balance-transfer calculator to confirm the switch pays off after costs.
The spread never changes — but the benchmark does
One subtlety worth understanding: under EBLR, the spread over the repo rate is fixed for the life of your loan. If you negotiated repo + 2.5% in a competitive year, that spread stays even if banks later offer new customers repo + 3%. This is why timing your loan — or your transfer — during a period of tight spreads is valuable. It is also why two EBLR borrowers can pay different rates: same benchmark, different spreads locked in at different times.
The honest takeaway
Your benchmark is not a technicality — it is the difference between a loan that tracks the RBI honestly and one that quietly overcharges you for years. Find out which one you are on today. If it is base rate or MCLR, ask to switch to EBLR, and if your bank resists, price a transfer. The rate-sensitivity calculator shows how a repo-linked loan responds to RBI moves, and the balance-transfer calculator tells you whether switching is worth it.
