Debt & EMIs

An EMI is the one financial decision that is genuinely hard to reverse. Once it is signed, a fixed share of every future salary is spoken for before any of it reaches a savings goal — and because each individual EMI is affordable in isolation, they stack until the total is not.

These posts work the arithmetic that decides those calls: what share of take-home pay is already committed, what a loan actually costs once interest is counted against what the same money could have earned invested, and whether buying a flat beats renting one over twenty years. The numbers are run on Indian salaries, Indian interest rates and Indian tax treatment, because the answers change materially when they are not.

Three questions come up more than any others, and they are the ones these posts answer in full. How much debt is too much, which is a question about the share of take-home pay going out as EMIs rather than about the size of any one loan. Whether to prepay a loan or invest the same money, which turns on the gap between the interest rate you are paying and the return you can reasonably expect. And where an EMI actually goes in the early years, which surprises most borrowers the first time they see the split between interest and principal.

Each answer is worked in rupees rather than left as a principle, because the arithmetic is where the intuition breaks. A rate that sounds small compounds over twenty years into a number most people would not have agreed to upfront. Every figure quoted here is tied to a named source — RBI data, lender disclosures, published studies — and the calculators linked from these posts run the same maths on your own numbers instead of the illustrative ones.
