This tool is useful to calculate the time value of money based on historical inflation and CPI values. To start, select an amount and two years, or browse the default calculation results.
The cumulative inflation rate in Bulgaria between December 1996 and May 2026 was 2,168.57%, meaning that overall prices were 22.7 times higher than they were in December 1996. In other words, the purchasing power of лв100 in Dec 1996 was equivalent to лв2,268.57 in May 2026. The average annual inflation rate over this period was 0.89%.
The chart below shows how the value of лв100 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 Bulgarian leva 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 1996-12 to 2026-05 | 2,168.57% |
| Avg. Monthly inflation from 1996-12 to 2026-05 | 0.89% |
| CPI 1996-12 | 7.08 |
| CPI 2026-05 | 160.71 |
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 months, we can use the following formula:
To obtain the values equivalent in buying power between December 1996 and May 2026, 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 лв100 worth today. There are 353 months between December 1996 and May 2026 and the average inflation rate was 0.8883%. Therefore, we can resolve the formula like this:

| лв5 leva in 1996-12 | → | лв113.43 leva in 2026-05 |
