CA explains home buying math: How much money do you need to earn for a dream house?

Buying a home continues to be one of the biggest aspirations for Indian families. An advertised price often creates the impression that ownership is within reach. However, a closer look at the numbers tells a very different story. Chartered Accountant Nitin Kaushik recently broke down the real financial impact of buying a house in an X post, explaining why many buyers underestimate both the upfront burden and the long-term monthly strain.

Kaushik pointed out that most homebuyers focus only on the headline cost of a property. In his example, an ₹80 lakh house appears manageable at first glance. But once additional expenses are added, the entry barrier rises sharply. Beyond the agreement value, buyers must account for stamp duty, registration charges, and other fees, which typically add another 8 to 10 percent. This alone can push costs up by roughly ₹8 lakh.

On top of that comes the mandatory down payment. With banks usually requiring at least 20 percent upfront, a buyer needs another ₹16 lakh before the loan even begins. Taken together, the actual cash needed at the start comes close to ₹24 lakh. Kaushik stressed that this initial outflow often catches first-time buyers off guard and can drain years of savings in one stroke.

Monthly commitment goes beyond the EMI

The financial pressure does not end once the keys are handed over. Kaushik explained that a home loan of ₹64 lakh, taken at around 9 percent interest for 20 years, would result in a monthly EMI of about ₹57,500. However, the EMI is only part of the story.

Regular expenses such as society maintenance charges, property tax, and insurance also need to be factored in. When these are added, the total monthly outflow climbs to around ₹64,000. According to Kaushik, this figure represents the real “monthly reality” of homeownership, not just the loan repayment.

How much income is actually needed

To assess whether this burden is sustainable, Kaushik applied the commonly accepted 30 percent rule. This guideline suggests that housing costs should ideally remain below 30 percent of take-home income to allow room for savings and daily expenses. Based on this logic, a monthly housing outflow of ₹64,000 would require a post-tax income of roughly ₹2.1 lakh.

In salary terms, this translates to an annual cost-to-company figure of around ₹30 to ₹33 lakh. Kaushik highlighted that many buyers earning significantly less still take on similar loans, which pushes their housing costs to nearly half their monthly income.

When EMIs start controlling your life

Kaushik warned that once EMIs consume 50 percent or more of a salary, financial stability becomes fragile. Long-term investments such as SIPs are often the first to be paused and eventually stopped. Lifestyle upgrades, emergency buffers, and even routine repairs begin to feel like luxuries. In such situations, a single job loss or corporate restructuring can trigger a serious financial crisis.

While a house is technically an asset, Kaushik emphasised that an oversized EMI can quickly turn it into a source of constant anxiety. He cautioned buyers against letting emotional decisions override financial logic, noting that mental stress is an invisible but very real cost of overborrowing.
