# Inflation Calculations

Soulver includes an inflation calculator based on the average yearly CPI change data published by the U.S. Bureau of Labor Statistics.

You can convert between currency amounts in various years, accounting for inflation, and predict the future value of an amount.

### Value of an amount from the past in today's dollars

```
what is $4.2k from 2003          | $6,795.58
$1 from 1997 is worth what today | $1.85
$10k from 1960 worth             | $102,877.00
value of $4.2k from 2003         | $6,795.58
```

### Today's dollars in a previous year

```
what was $500 worth in 1997 | $269.56
value of $500 in 1997       | $269.56
$500 is worth what in 1997  | $269.56
```

### Converting between two specific years

```
what is $285.44 in 1997 worth in 2022 | $519.80
$1 from 1997 is worth what in 2021    | $1.69
```

### Using "dollars" phrasing

```
$10 million in 1985 dollars | $27.668M
$90k in 1996 dollars        | ~$170k
```

### Predicting future value with an assumed inflation rate

```
value of $500 in 2028 assuming 5% inflation           | $411.35
what will $1M be worth in 2040 assuming 10% inflation | $217,629.00
purchasing power of $500 in 2028 at 5% inflation      | $411.35
```

Future inflation predictions require you to specify an assumed inflation rate (e.g. "assuming 5% inflation").
