What is purchasing power?
Purchasing power is the amount of goods and services that a given amount of money can buy. When prices increase, the same amount of money buys fewer goods and services, meaning its real purchasing power declines.

Purchasing Power Calculator
Calculate how inflation affects the real value of money over time. Estimate future purchasing power, cumulative inflation, and the amount needed to maintain today’s standard of living.
Quick answer:Inflation compounds over time. The longer inflation continues, the less purchasing power the same amount of money generally has.

Purchasing power after 20 years约 55.37%
At an assumed average inflation rate of 3% per year, the purchasing power of 100,000 CNY after 20 years would be about 55.37% of today’s purchasing power. To maintain the same purchasing ability as 100,000 CNY today, approximately 180,611 CNY would be needed in 20 years.
Purchasing Power Formula
This calculator uses a compound inflation model, assuming prices increase each year based on the selected inflation rate.
Future purchasing power
Future purchasing power = Current amount ÷ (1 + inflation rate)ⁿ
Purchasing power retained
Purchasing power retained = 1 ÷ (1 + inflation rate)ⁿ
Future required amount
Future required amount = Current living cost × (1 + inflation rate)ⁿ
Direct answer
Purchasing power describes how many goods and services a given amount of money can buy. Higher inflation and longer periods generally reduce the purchasing power of the same amount of money.
Why does inflation reduce purchasing power?
Inflation means the overall price level increases over time. If income, savings, or asset growth does not keep pace with inflation, the same amount of money will buy fewer goods and services. Because inflation compounds, its effect is usually more significant over long periods.
How is purchasing power calculated?
Under a fixed inflation assumption, future purchasing power can be estimated by dividing the current amount by (1 + inflation rate) raised to the number of years. The future amount required to maintain the same standard of living can be calculated by multiplying the current cost by the same inflation factor.
How much will 100,000 CNY be worth in 20 years?
At an assumed average inflation rate of 3% per year, the purchasing power retained after 20 years is about 55.37%. In purchasing-power terms, 100,000 CNY today would be equivalent to roughly 55,367 CNY of today’s purchasing power after 20 years. To maintain the purchasing power of 100,000 CNY today, about 180,611 CNY would be required.
What does a 3% inflation rate mean?
If prices increase by an average of 3% per year, the price level compounds over time. A 3% annual increase may appear small in the short term, but its effect becomes much larger over 10, 20, or 30 years.
How much money will be needed to maintain the same standard of living?
If maintaining today’s lifestyle costs 100,000 CNY per year, the future cost will increase under a positive inflation assumption. At 3% annual inflation, the equivalent cost after 20 years would be approximately 180,611 CNY.

Purchasing Power Calculator FAQ
Common questions about purchasing power, inflation, and the future value of money.
What is purchasing power?
Purchasing power is the amount of goods and services that a given amount of money can buy. When prices increase, the same amount of money buys fewer goods and services.
How does inflation reduce purchasing power?
Inflation increases the general price level over time. As prices rise, the same amount of money can purchase fewer goods and services.
How much will 100,000 CNY be worth in 20 years?
At an assumed average inflation rate of 3% per year, 100,000 CNY would retain approximately 55.37% of its current purchasing power after 20 years.
What does a 3% inflation rate mean?
A 3% annual inflation rate means that, under a simplified constant-rate assumption, prices increase by approximately 3% each year. The effect compounds over time.
How do you calculate future purchasing power?
Future purchasing power can be estimated by dividing the current amount by (1 + inflation rate) raised to the number of years.
How much money will be needed in the future?
The future amount required to maintain the same purchasing ability can be estimated by multiplying the current amount by (1 + inflation rate) raised to the number of years.
