Inflation vs Raise Calculator

How inflation creates paycheck friction

A raise advertised in nominal dollars can still lose purchasing power if prices rise faster. Headline CPI is one path; rent-heavy personal inflation can diverge.

Taxes complicate “keeping up.” Bracket dynamics and higher nominal income can increase tax drag even when real income is flat — pair this tool with paycheck take-home.

How to use this calculator

Enter starting pay, an assumed annual raise path, and an inflation assumption. Stay consistent with one BLS CPI series across years in your scenario.

Interpret “today dollars” as purchasing power relative to the starting year, not as a promise of future cash on a stub.

Worked example

Start at $70,000. Assume 3% raises for five years and 3% inflation each year. Roughly, real pay treads water before tax — the nominal paycheck grows while purchasing power barely moves.

Shift inflation to 4% with the same 3% raises and real pay erodes each year. The gap compounds quietly the same way fee drag compounds in a 401(k).

After the real-pay result, open paycheck take-home with the new nominal salary and your state rate scenario. Net cash is what funds rent and debt payments — not the gross raise announcement.

Using CPI responsibly

BLS publishes multiple CPI series. Pick one and stay consistent. This is not a Social Security COLA calculator and not advice to demand a specific raise.

Assumptions

• Constant raise and inflation percentages you enter — simplified compounding.
• “Today dollars” purchasing-power frame versus starting year.
• No taxes, benefits, or hours changes unless you adjust outside the tool.
• Not a COLA, union COLA, or Social Security calculator.
• Educational macro scenario — not a forecast of your employer’s budget.
