Inflation & Purchasing Power Calculator

Inflation reduces money's purchasing power over time. This calculator shows that effect for an inflation rate you provide.

How we calculate

Divides the amount by the accumulated inflation factor to show today's equivalent purchasing power in the future.

Future purchasing power = amount ÷ (1 + annual inflation)^years.

Poder de compra futuro = valor ÷ (1 + inflação)ⁿ

R$ 10,000 today, at 4.5% annual inflation, is worth about R$ 6,439 in purchasing power in 10 years.

The higher the inflation rate and term, the greater the loss in purchasing power.

This site does not automatically fetch official inflation indexes — you must supply the rate. Assumes a constant rate.
