Is there a calculator or standard method of computation where you could get the relative difference in spending power of X USD in a given city/year from a given city/year?

For example, what would be the relative increase/decrease in spending power of ($10,000 in San Francisco Ca, 2022) to (10,000 in Phoenix Az, 1999)?

There is a standard method. It is called Purchasing Power Parity (PPP) or in case it is for region it is sometimes called Regional Price Parity (RPP).

I found this dataset that has purchasing power index for some cities, but only largest cities are included.
