MCLR vs Repo-Linked Home Loan: Which Is Cheaper?

The RBI cuts the repo rate. The news celebrates “cheaper home loans.” And then you check your own statement — and your EMI hasn’t moved a paisa. If that’s ever happened to you, the culprit is almost certainly the benchmark your floating-rate loan is tied to. Two borrowers with identical loans can experience the same rate cut completely differently, purely because one is on MCLR and the other is repo-linked. That single design choice can cost or save you lakhs over twenty years.

Here’s how the two work, and why the faster one wins.

The two benchmarks, plainly

Every floating-rate home loan is priced as a benchmark + a spread. When the benchmark moves, your interest rate moves with it. The question is which benchmark, and how quickly it reacts.

• MCLR (Marginal Cost of Funds based Lending Rate) is an internal benchmark — each bank calculates its own, based largely on its cost of funds. Banks revise it on their own cycle, and crucially, they tend to be quick to raise it when rates climb and slow to lower it when rates fall.
• Repo-linked / EBLR (External Benchmark Lending Rate) ties your loan directly to the RBI’s repo rate. Since October 2019, the RBI has required new floating retail loans (home, auto, personal) to be linked to an external benchmark. Because it’s external and rule-bound, it resets transparently and on a fixed schedule — usually quarterly — passing RBI changes through quickly.

The phrase that matters here is monetary transmission — how fast a central bank’s rate decision actually reaches your EMI. Repo-linked loans transmit fast. MCLR loans lag. And in a falling-rate environment, that lag is money straight out of your pocket.

Why the lag costs real money

It’s tempting to think “a few months of delay, what’s the harm?” But a rate difference isn’t a one-month event — it compounds across the entire outstanding balance for as long as you carry the gap. To see the scale, here’s what half a percentage point does on a ₹50,00,000 loan over 20 years (240 months).

Interest rate	Total interest over the loan
8.5%	≈ ₹54,13,879
9.0%	≈ ₹57,96,711

That 0.5% difference is worth about ₹3,82,832 over the life of the loan, and roughly ₹1,595 a month on the EMI.

Now connect that to benchmarks. If the RBI cuts rates and your repo-linked loan passes the cut on within a quarter, you start saving almost immediately. If you’re on MCLR and your bank drags its feet for several reset cycles — or barely moves the rate at all — you keep paying the higher rate on your full balance the whole time. You’re effectively sitting on the wrong side of that ₹3.83 lakh gap, not because of your credit or your negotiation, but because of which benchmark you happen to be on.

If you want to internalise just how powerful small rate changes are, our piece on how a half-percent rate difference changes total interest makes it vivid — and how interest rate affects EMI shows the mechanics.

So is repo-linked always cheaper?

Not automatically — and this is where honesty matters. A repo-linked loan isn’t magically a lower rate than MCLR on day one; the spread your lender adds can differ. What repo-linked loans reliably give you is faster, more transparent transmission: when the RBI moves, you find out where you stand quickly, in both directions.

That cuts both ways. Repo-linked loans pass on cuts faster (good for you), but they also pass on hikes faster (less comfortable when rates are rising). MCLR smooths the ride a little. For most borrowers, though, the transparency and the benefit of quick rate-cut transmission make repo-linked the better structure over a long tenure — you always know your rate is genuinely tracking the market rather than your bank’s internal discretion.

How to check — and switch — your benchmark

You can find your benchmark in minutes:

• Read your loan agreement or latest statement. It will say whether your rate is linked to MCLR, EBLR/RLLR (repo-linked), or an older base rate.
• Check your reset frequency. Repo-linked loans typically reset quarterly. If you’re on MCLR, note the reset period — that’s how long you can be stuck after a rate change.
• Ask your lender about switching. Banks generally allow existing borrowers to move from MCLR (or an older base-rate loan) to a repo-linked structure, often for a small conversion or administrative fee.

Two practical cautions. First, weigh the conversion cost against the saving — on a large, long loan the saving usually dwarfs a one-time fee, but run the numbers. Second, switching within your own bank is different from a full balance transfer to another lender; if you’re chasing a materially lower spread, a transfer might serve you better, and our guide on home loan balance transfer — when is it worth it covers exactly that calculation.

All of this is general information. The exact options, fees, and spreads vary by lender and by your loan vintage, so confirm the specifics with your bank before you decide.

The takeaway

The benchmark isn’t fine print — it’s the dial that decides how quickly an RBI rate cut becomes your saving. On a ₹50 lakh, 20-year loan, being on the wrong side of just 0.5% is about ₹3.83 lakh over the term. Repo-linked loans don’t guarantee a lower starting rate, but they guarantee you won’t be quietly left behind when rates fall.

Pull out your loan statement today and find your benchmark. If you’re still on MCLR or an old base rate and rates are easing, ask your lender about moving to repo-linked. Then model your own scenario on the home loan calculator — a few minutes of checking can be worth several lakh over the years you’ll hold the loan.
