What Moves the Needle Most
How much each factor changes your Future Cost across its full range. Inflation Rate has the biggest impact.
Focus your attention on Inflation Rate — getting it right matters most. Factors lower down move the result less, so rough estimates there are fine.
Confidence & Assumptions
The result swings widely between best and worst cases — it depends heavily on assumptions that are hard to predict.
Future Cost: €160,357 (worst) → €90,306 (expected) → €74,297 (best)
These are the estimates the result depends on. Adjust them (and the Advanced inputs) to match your real situation — the closer they are to reality, the more reliable your decision.

How This Calculator Works
What this calculator does
This calculator shows how prices increase over time due to inflation and how the purchasing power of your money decreases.
How the calculation works
Inflation compounds annually. An item costing €P today will cost P × (1 + r)^t after t years at inflation rate r. Conversely, €P today will only have the purchasing power of P / (1 + r)^t in the future.
Formula
Future Cost = Present Cost × (1 + r)^t Real Value = Present Amount / (1 + r)^t r = inflation rate, t = years
Sources & defaults
- Eurostat / national CPI
Default inflation ~2–3% unless you override it
Example
€50,000 at 3% inflation for 20 years: Future cost = €50,000 × 1.03^20 = €90,305. You need €90,305 to buy what €50,000 buys today.

Check metrics, cost breakdown, comparison tables, and best / expected / worst scenarios. Use sliders to stress-test assumptions.
- 4Decide with the verdict
Read the decision engine recommendation and FAQ. Example: €50,000 at 3% inflation for 20 years: Future cost = €50,000 × 1.03^20 = €90,305. You need €90,305 to buy what €50,000 buys today.
Factors to Consider
- General inflation averages 2-3% in developed economies
- Healthcare and education inflation often runs higher (5-8%)
- Wage growth should ideally outpace inflation
- Long-term financial plans must account for inflation
Common Mistakes
- Using today's prices for future financial planning
- Forgetting that wages also (usually) increase with inflation
- Not distinguishing between nominal and real returns
- Underestimating the cumulative effect of inflation over decades
Frequently Asked Questions
What is inflation?+
Inflation is the general increase in prices over time, which reduces the purchasing power of money. A euro today buys less than a euro did 10 years ago.
What is a normal inflation rate?+
Most developed economies target 2-3% annual inflation. Developing countries may see 4-6%. Hyperinflation (>10%) is rare but devastating.
How does inflation affect investments?+
Inflation erodes real returns. If your investment earns 7% and inflation is 3%, your real return is only ~4%. Always compare returns to inflation.
