Minor nit about math in some previous posts: inflation is multiplicative, not additive, because the effects compound year over year.
If you buy something for $10k, and experience three years of 2%, one of 8%, one 7%, don't add, instead you do this math:
Total inflation = 1.02*1.02*1.02*1.08*1.07
= 1.2263319648
This tells you there's been 22.6% inflation, not the 21% you'd get from adding, so your five-years-ago $10k would now be $12,260 rather than $12,100 (huge difference lol)
If you don't think this is a big deal, consider 8% inflation over 10 years. Adding, you'd get 80%. Compounded correctly gets you 116%.
