## How it works

Future cost = current amount × (1 + annual inflation rate)^years. Future purchasing power divides the current amount by the same cumulative factor.

## Worked example

$1,000 with constant 3% annual inflation for 10 years corresponds to about $1,343.92 in future cost and about $744.09 of future purchasing power.

## Assumptions

- The entered inflation rate remains constant for the entire period.
- The model describes a general price-level scenario; individual goods can move differently.
- Taxes, investment returns, income growth, and currency changes are excluded.

## Common questions

### Is this an inflation forecast?

No. It is constant-rate scenario arithmetic using your assumption.

### Why can my personal costs differ?

Households buy different baskets, and prices for individual goods do not move uniformly.

### What does purchasing power mean here?

It is the amount of future goods the current sum could buy if the selected general price level compounded consistently.
