What your salary slip doesn't tell you about affordability

“I earn 8 lakhs a year” and “I have ₹55,000 to work with this month” are two completely different statements, and a lot of EMI decisions get made using the first number when only the second one matters.

CTC — cost to company — includes provident fund contributions, gratuity, insurance, and other components that never actually land in a bank account in a given month. What shows up for spending, saving, and paying EMIs is take-home pay, and it’s routinely 15–25% lower than the annual CTC divided by twelve would suggest.

Where the confusion creeps in

Affordability math done against CTC quietly overstates what’s available. Someone on a ₹9 lakh CTC might assume roughly ₹75,000 a month to work with, when actual take-home lands closer to ₹62,000 once deductions are out. Run a “40% of income” EMI ceiling against the wrong number, and the safe-looking limit is already off by a meaningful margin before a single EMI has been signed.

This isn’t a rare mistake — it’s an easy one, because CTC is the number that gets talked about, negotiated, and remembered. Take-home is the number that quietly does all the work.

The number that actually matters here

Whatever ratio or rule you’re using to judge if an EMI is comfortable, it needs to be run against what actually lands in the account each month — not the headline figure from an offer letter or appraisal conversation. It’s a small correction to make, and it changes the answer more often than people expect.

Dette’s Pre-Purchase Check and Debt Score both work off actual monthly income, exactly for this reason — the number that pays the EMI, not the number on the letterhead.
