See how much a rupee amount will be worth in the future, or find out what an old amount would be worth today, adjusted for inflation.
Future value uses the formula: Amount × (1 + inflation rate)^years — showing how many rupees you'd need in the future to buy what today's amount buys now. Past value works in reverse: Amount ÷ (1 + inflation rate)^years — showing what today's amount would have been worth (in purchasing power) a number of years ago.
This is the same underlying math used to explain why "my salary went up but I don't feel richer" — if your income grows slower than inflation, your real purchasing power is actually shrinking even as the number on your payslip grows.
India's long-term average CPI inflation has generally been in the 5-7% range over the past decade, though it fluctuates year to year. For future planning, 6% is a commonly used assumption.
If your salary hike is lower than the inflation rate, your real purchasing power actually decreases even though your nominal salary went up. For example, a 5% raise during 7% inflation means you can buy less than before, in real terms.
