Two Incomes, One EMI: Stress-Testing a Rs 1 Crore Bengaluru Home Loan

36 per cent on a good month, 62 per cent on a bad one. Those are the two numbers a Bengaluru couple with a combined take-home pay of Rs 2.4 lakh a month would see if they took a Rs 1 crore, 20-year home loan at an illustrative 8.5 per cent, in our worked example. The first is the EMI's share of income with both salaries coming in. The second is its share if the partner earning Rs 1 lakh a month stopped working.

The RBI website lists the policy repo rate at 5.50 per cent, after the Monetary Policy Committee voted unanimously on 7 October 2026 to raise it by 25 basis points, according to the Governor's statement. Rate moves get attention. Income moves can matter as much for a two-earner household. This guide runs a simple stress test. It does not describe any lender's eligibility rules or recommend a loan size.

The short answer. In our example, a Rs 1 crore, 20-year loan at an illustrative 8.5 per cent has an EMI of about Rs 86,782. For a household taking home Rs 2.4 lakh a month, that is about 36 per cent of income. If the Rs 1 lakh earner stops, it is about 62 per cent of the remaining Rs 1.4 lakh; if the Rs 1.4 lakh earner stops, it is about 87 per cent of the remaining Rs 1 lakh. Six months of EMIs come to about Rs 5.21 lakh. The trade-off: two incomes let a household borrow more, but the larger the loan, the deeper the hole if one income pauses.

What does the EMI look like on two incomes?

Comfortable on paper. Using the standard reducing-balance formula with monthly compounding, and assuming the rate stays constant, a Rs 1 crore loan over 20 years at 8.5 per cent has an EMI of about Rs 86,782. Against a combined take-home pay of Rs 2.4 lakh a month, made up of Rs 1.4 lakh and Rs 1 lakh, that is about 36.2 per cent.

That leaves about Rs 1.53 lakh a month for everything else: household costs, school fees, insurance, maintenance charges, savings. The figures here are illustrative. The incomes, rate and loan size are not drawn from any real household or lender.

What happens if one income stops?

The EMI does not change, but its weight does. The table shows the same loan against three income situations.

In the second row, the household still pays the EMI but has about Rs 53,000 left for everything else. In the third, it has about Rs 13,000. That is the gap a buffer, insurance or a smaller loan has to fill.

Time makes the gap concrete. If the Rs 1 lakh earner's income stopped for three months, the household would pay about Rs 2.60 lakh in EMIs over that period out of about Rs 4.2 lakh of remaining take-home pay. Over six months, it would pay about Rs 5.21 lakh out of about Rs 8.4 lakh. Whatever is left has to cover every other household cost for those months.

How big a loan fits one income?

Smaller, on the same arithmetic. One way to stress-test is to ask what loan the higher single income could carry on its own if the EMI were held to a share the household is comfortable with.

At 8.5 per cent over 20 years, an EMI of Rs 56,000, which is 40 per cent of Rs 1.4 lakh, supports a loan of about Rs 64.5 lakh. An EMI of Rs 48,000 supports about Rs 55.3 lakh. On two incomes, an EMI of Rs 72,000, which is 30 per cent of Rs 2.4 lakh, supports about Rs 83 lakh.

These percentages are illustrations of a household's own comfort level, not lender rules. Lenders apply their own assessments, which you can ask about. The point is to see the distance between the loan two incomes can support and the loan one income can support, and to decide how much of that distance you are willing to bridge with savings or insurance.

Our stress test for Rs 50 lakh to Rs 1.5 crore loans shows how rate moves add to the picture.

What if a rate rise comes on top?

The two stresses stack. If the rate on the same Rs 1 crore, 20-year loan rose from 8.5 per cent to 9 per cent, the EMI would be about Rs 89,973; at 9.5 per cent, about Rs 93,213. With both incomes, those are about 37.5 per cent and 38.8 per cent of Rs 2.4 lakh, a modest change.

With one income of Rs 1.4 lakh, they are about 64.3 per cent and 66.6 per cent. With one income of Rs 1 lakh, they would be about 90 per cent and 93 per cent, leaving very little for anything else. A rate rise that looks small for a two-income household becomes much heavier once one income has paused.

That is why a stress test that only looks at rates, or only at incomes, can understate the risk. Running the two together, even roughly, shows the combinations that would strain the budget most, and helps a household decide how large a buffer, and how large a loan, it is comfortable with.

How can a household build a buffer?

By deciding in advance how long a gap it wants to cover. In our example, six months of EMIs is about Rs 5.21 lakh, before any other living costs. A household might choose more or fewer months depending on how quickly an income could be replaced and what other savings it has.

One approach is to set the buffer aside before booking, alongside the down payment, stamp duty and registration costs. Another is to build it in the first year after taking the loan. Either way, it helps to keep it separate from the down payment so it is not spent on the purchase itself.

The size of the buffer also interacts with the loan. A larger down payment reduces the EMI and so reduces the buffer needed for each month of cover. Our guide to down payment choices on a Rs 1.25 crore flat shows how each extra slice of down payment changes the EMI.

What should joint borrowers check in their loan papers?

How the loan treats each of you. Each borrower's obligations are set out in the loan documents, so read them rather than assuming they follow who earns more. Read the sanction letter and agreement for who is a borrower, who is a co-borrower, and what happens to repayment if one person's income changes.

Ask the lender, in writing, how it would handle a temporary income gap, and whether any insurance offered with the loan covers loss of income or only death or disability. Insurance terms vary, so read the policy wording rather than relying on a summary.

It also helps to agree, as a household, what you would cut first if one income paused: discretionary spending, a planned purchase, or contributions to other savings. Writing that down before signing makes the plan easier to follow if it is ever needed.

This is a budgeting exercise, not advice to buy or not to buy. Its value is in making a hard conversation concrete before the agreement is signed.

How should a two-income Bengaluru household stress-test a loan?

By running the numbers for each earner, not only for the household.

1. Write down each earner's monthly take-home pay separately, and the combined figure.
2. Calculate the EMI on the loan you are considering, at the quoted rate and at 50 and 100 basis points higher.
3. Work out the EMI as a share of combined pay, and as a share of each single income.
4. List your other fixed monthly costs and see what is left in each scenario.
5. Decide how many months of EMIs and living costs you want in a separate buffer, and how you will build it.
6. Read the loan agreement for each borrower's obligations, and ask what insurance offered with the loan actually covers.
7. If the single-income scenarios leave too little, consider a smaller loan, a larger down payment or a longer saving period before booking.

Frequently asked questions

What is the EMI on a Rs 1 crore home loan over 20 years?

In our worked example at an illustrative 8.5 per cent, the EMI is about Rs 86,782 a month, using the standard reducing-balance formula and assuming the rate stays constant. Your own EMI depends on the rate, tenure and terms in your sanction letter.

What happens to my EMI share if one earner loses income?

In our example of a household earning Rs 2.4 lakh a month after tax, the Rs 86,782 EMI is about 36 per cent of income. If an earner taking home Rs 1 lakh stops, it becomes about 62 per cent of the remaining Rs 1.4 lakh.

How big an emergency fund should cover a home loan EMI?

This guide does not set a figure. In our example, six months of a Rs 86,782 EMI comes to about Rs 5.21 lakh. A household can decide how many months of EMI and living costs it wants to cover, based on how quickly it could replace a lost income.

Can a joint home loan be repaid by one borrower?

The loan terms decide each borrower's obligations, so read your sanction letter and loan agreement. In our arithmetic, a Rs 1 crore loan's EMI of about Rs 86,782 is roughly 62 per cent of a Rs 1.4 lakh single take-home income, which leaves little room for other costs.
