The cumulative inflation rate in India between 1980 and 1987 was 84.66%, meaning that overall prices were 1.85 times higher than they were in 1980. In other words, the purchasing power of ₹100 in 1980 was equivalent to ₹184.66 in 1987. The average annual inflation rate over this period was 9.16%.
The chart below shows how the value of ₹100 changes over time when adjusted for inflation, based on Consumer Price Index (CPI) data. All values are equivalent in terms of purchasing power, indicating how much money would be needed each year to buy the same goods or services.
All calculations are performed in Indian rupees with six-decimal precision, though displayed values are rounded to two decimals for readability. Inflation figures are sourced from official government and international reports released monthly.
The following table contains relevant indicators:
| Indicator | Value |
|---|---|
| Cumulative inflation from 1980 to 1987 | 84.66% |
| Avg. Annual inflation from 1980 to 1987 | 9.16% |
| CPI 1980 | 6.55 |
| CPI 1987 | 12.1 |
There are several ways to calculate the time value of money. Depending on the data available, results can be obtained by using the Consumer Price Index (CPI) formula or the compound interest formula.
When we have both the start and end years, we can use the following formula:
To obtain the values equivalent in buying power between 1980 and 1987, use the corresponding CPI values:
Given that money changes with time as a result of an inflation rate that acts as compound interest, we can use the following formula: FV = PV × (1 + i)n, where:
In this case, the future value represents the final amount obtained after applying the inflation rate to our initial value. In other words, it indicates how much are ₹100 worth today. There are 7 years between 1980 and 1987 and the average inflation rate was 9.1574%. Therefore, we can resolve the formula like this:
