Inflation timeline in Mexico (1981 - 2025)

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 Mexican pesos 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. To convert historical amounts into today's pesos, we use the most recent CPI data available and extrapolate it to estimate the CPI for today.

The following table contains relevant indicators:

Indicator Value
Cumulative inflation 1981-2024 184,528.11%
Cumulative inflation 1981-today 193,812.46%
Avg. Annual inflation 1981-2024 19.11%

CPI 2024 135.38
CPI 2025-10 (latest official data) 141.71
CPI today 142.19

How to calculate today's value of money after inflation?

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.

Using the CPI formula

When we have both the start and end years, we can use the following formula:

Valuet =Value0 ×
CPIt/CPI0

To obtain the values equivalent in buying power between 1981 and 2024, use the corresponding CPI values:

Value2024
=Value1981 ×
CPI2024/CPI1981
=$ 100 ×
135.38/0.07
$184,628.11

To obtain the equivalent value today (present value), plug in the CPI for today, which is estimated as 142.19:

Valuetoday
=Value1981 ×
CPItoday/CPI1981
=$ 100 ×
142.19/0.07
$193,912.46

Alternative: Using the compound interest formula

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:

  • FV: Future Value
  • PV: Present Value
  • i: Interest rate (inflation)
  • n: Number of times the interest is compounded (i.e. # of years)

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 43 years between 1981 and 2024 and the average inflation rate was 19.1133%. Therefore, we can resolve the formula like this:

Value2024
=PV × (1 + i)n
=$100 × (1 + 0.191133)43
$184,628.11
