Purchasing Power Calculator
An illustrative tool to help you understand how inflation affects the real value of a fixed income over time. For educational purposes only.
How much does inflation cost you?
This calculator uses the standard purchasing power formula. Enter a monthly income amount, an annual inflation rate, and a number of years to see how the real value changes over time.
How to read this
The formula used is: Real Value = Nominal Income / (1 + inflation rate)^years. This shows how many goods and services your income could buy in today's prices compared to the future.
What purchasing power actually means
Purchasing power refers to the quantity of goods or services that a unit of money can buy at a given point in time. When prices rise — that is, when inflation occurs — the same amount of money buys fewer goods and services. Your nominal income may stay the same, but your real income falls.
For microentrepreneurs and independent workers in Colombia, this matters in two directions. First, your own expenses become more costly over time if your income does not grow proportionally. Second, your customers face the same dynamic — their purchasing power also erodes, which affects how much they can spend at your business.
Understanding purchasing power is not just about your own money. It is about understanding the economic environment your customers live in.
Terms worth knowing
IPC (Índice de Precios al Consumidor)
Colombia's Consumer Price Index, published by DANE. It measures the average change in prices paid by urban consumers for a basket of goods and services over time.
Nominal vs. Real Income
Nominal income is the number on your paycheck or sales total. Real income is what that number actually buys — adjusted for inflation. The difference between the two is what purchasing power erosion looks like.
Inflation Rate
The percentage change in the general price level over a period, usually one year. In Colombia, the Banco de la República targets inflation within a defined range as part of its monetary policy.
Real Wage
Your wage or income adjusted for inflation. If your income grew by 5% but inflation was 9%, your real wage actually fell — you can buy less than before despite earning more in nominal terms.
