For each year t: Income(t) = Income(0) * (1 + Raise)^t; Expenses(t) = Expenses(0) * (1 + Inflation)^t. Annual Surplus(t) = (Income(t) - Expenses(t)) * 12. Cumulative Savings is the sum of annual surpluses compounded.
Because salary growth (4%) outpaces expense inflation (3%), annual cash surplus expands from $14,400 to $17,064 by year 3.

Most people plan only one month at a time, blinding them to future lifestyle creep or compounding surpluses that could accelerate financial independence.
Historically, consumer price index (CPI) inflation averages 2.5% to 3.5% per year over long horizons.
Lifestyle creep occurs when discretionary spending rises in lockstep with salary raises, preventing people from accumulating wealth despite higher pay.
This calculator focuses on raw cash flow accumulation. To model interest on this surplus, feed the results into our Compound Interest Calculator.
If inflation exceeds salary growth, your monthly surplus will shrink each year, signaling the need for career advancement or cost reductions.
