How to Use This Calculator

Enter your annual income, which stays constant after a move.
Set the cost of living (COL) index for your current city (100 is the national baseline; cities like San Francisco or New York are 150-200+).
Enter the COL index for your destination city.
Review the equivalent lifestyle spending in the new location and the annual cash flow freed up by the move.
Use this to evaluate whether relocating to a lower-cost city could significantly accelerate your savings.

How this is calculated

Worked example, using the default values

Identify Input Parameters
Annual income = 120000, COL index (from) = 150, COL index (to) = 95 = 3 input(s) provided
Calculate Maintained lifestyle spend
Maintained lifestyle spend = income * ratio
76000 = $76,000
Calculate Cash flow freed
Cash flow freed = income - impliedSpend
44000 = $44,000
Calculate COL ratio
COL ratio = idxTo / idxFrom
0.633 = 0.633
