What was happening in 1980
By 1980 India had absorbed the oil shocks and inflation had settled into high single digits, where it would broadly remain until liberalisation. A rupee saved in 1980 has since lost the large majority of its purchasing power.
Inflation during 1980 itself was 11.3%. Across the 45 years since, prices have risen 23.9× in total, which works out to an average of 7.3% compounded annually. Put the other way round, a rupee from 1980 retains about 4.2% 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 1980 would have lost roughly 95.8% of what it could buy, without a single rupee being spent. To merely stand still, savings had to earn 7.3% 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.
