I was trying to calculate how much a certain amount of fiat would be worth in 10 years and I came across [this gem](https://smartasset.com/investing/inflation-calculator). Anyone know how they can come up with this shit?

Also, if I want to orange pill someone by telling them their fiat is worth less in buying power over time just by holding on to it, does anyone know how to calculate the number over multiple years?
