What the result means
Inflation causes prices to rise over time, meaning the same amount of money buys less in the future. The future value shows how much the same goods will cost, while the purchasing power shows what your money will be worth in today's terms.
How to use this calculator
- 1Enter the amount of money in rupees.
- 2Enter the expected annual inflation rate.
- 3Enter the number of years.
- 4Press Calculate to see the future value and the purchasing power of your money.
- 5Use the result to understand how much more things will cost in the future.
The formula
The calculation uses a standard, verifiable formula. Here it is in its simplest form.
Future value = Amount × (1 + rate/100)^years
Purchasing power = Amount ÷ (1 + rate/100)^years
What each variable means
| Symbol | Name | Description |
|---|---|---|
| A | Amount | The amount of money you are considering. |
| R | Inflation rate | The expected annual inflation rate. |
| Y | Years | The number of years into the future. |
Step-by-step example
Example: ₹1,00,000 at 6% inflation for 10 years
Amount:₹1,00,000Inflation rate:6%Years:10
- 1Future value = 1,00,000 × (1.06)^10 ≈ ₹1,79,085
- 2Purchasing power = 1,00,000 ÷ (1.06)^10 ≈ ₹55,840
- 3Your ₹1,00,000 today will buy what ₹55,840 buys today in 10 years.
Result
Future value ≈ ₹1,79,085; purchasing power ≈ ₹55,840
What changes the result
- Higher inflation rates dramatically reduce purchasing power over time.
- Longer time horizons amplify the effect of inflation.
- Investment returns must exceed inflation to grow real wealth.
Edge cases to be aware of
Unusual situations handled correctly
- If inflation is 0%, future value equals the current amount.
- Negative inflation (deflation) would increase purchasing power.
- Very high inflation rates can make money nearly worthless over long periods.
Common mistakes
Avoid these errors
- Confusing future value with purchasing power.
- Ignoring inflation when planning long-term savings.
- Using nominal returns without adjusting for inflation.
Assumptions
- The inflation rate is constant over the period.
- Inflation compounds annually.
- The rate reflects general price increases, not specific goods.
Limitations
- Actual inflation varies year to year and by category.
- Does not account for taxes on investment returns.
- This is an estimate for planning, not a prediction.
Frequently asked questions
What is the difference between nominal and real returns?+
Nominal return is the raw percentage gain on an investment. Real return is the nominal return minus inflation, showing your actual increase in purchasing power.
How does inflation affect my savings?+
If your savings earn less than the inflation rate, their real value decreases over time. For example, money earning 4% while inflation is 6% loses 2% of its purchasing power each year.
What is a typical inflation rate?+
In India, inflation has historically ranged from 4–6% annually, though it can spike higher in some years. Central banks generally target around 4%.
