What was happening in 1970
The 1970s opened calmly but turned into the most inflationary decade in independent India's history. Prices rose 17% in 1973 and almost 29% in 1974 as the global oil shock hit an economy already short of food and foreign exchange.
Inflation during 1970 itself was 5.1%. Across the 55 years since, prices have risen 50.7× in total, which works out to an average of 7.4% compounded annually. Put the other way round, a rupee from 1970 retains about 2% of its original buying power today.
Why this matters
Long-run numbers like these are the clearest argument against holding wealth in cash. Money left idle since 1970 would have lost roughly 98% of what it could buy, without a single rupee being spent. To merely stand still, savings had to earn 7.4% a year after tax — and to actually grow, more than that.
The same logic applies forwards. If you are planning for a goal decades away, the sum you need is not today's price but tomorrow's. Our inflation calculator projects that forward, and the FIRE calculator applies it to a full retirement corpus.
