You get a 5% raise from $70,000 to $73,500. You expect 5% more take-home pay. Your next paycheck is 3.8% higher. Where did the other 1.2% go?
Marginal tax rates eat raises
Your raise is taxed at your marginal rate, not your effective rate. If you're in the 22% federal bracket, 6.2% Social Security, 1.45% Medicare, and 5% state tax, your marginal rate is 34.65%.
A $3,500 raise produces:
- Federal tax: $3,500 * 22% = $770
- Social Security: $3,500 * 6.2% = $217
- Medicare: $3,500 * 1.45% = $50.75
- State tax: $3,500 * 5% = $175
- Total additional tax: $1,212.75
- Net increase: $2,287.25
Your take-home increases by $2,287 / $52,850 (original net) = 4.33%, not 5%.
The bracket boundary effect
If a raise pushes you into a higher federal bracket, the marginal rate on the portion in the new bracket is higher. But only that portion. Going from $95,000 to $105,000 means the first $5,375 (up to the bracket threshold at $100,525 for 2024) is taxed at 22%, and the remaining $4,625 is taxed at 24%.
The weighted marginal rate for the full raise: ($5,375 * 22% + $4,625 * 24%) / $10,000 = 22.93%. This is barely higher than 22%. Bracket transitions are gradual, not cliff edges.
Inflation-adjusted raises
A 3% raise when inflation is 3.5% is a pay cut. Your nominal salary increased, but your purchasing power decreased. The real raise is:
real_increase = ((1 + nominal_raise) / (1 + inflation)) - 1
real_increase = (1.03 / 1.035) - 1 = -0.48%
You're earning 0.48% less in real terms despite the "raise."
From 2020 to 2023, cumulative inflation was approximately 18%. Someone who received 3% annual raises over that period got about 9.3% in cumulative raises against 18% inflation, a real income loss of approximately 7.5%.
Negotiation math
Knowing the actual take-home impact helps in negotiation. When negotiating between a $90,000 and $95,000 offer, the real difference is:
$5,000 gross * (1 - 0.3465 marginal rate) = $3,268/year net = $272/month = $126/biweekly paycheck.
That's real money but might change how hard you push. Alternatively, negotiating for benefits that aren't taxed (additional PTO, remote work flexibility, education budget) can provide more value per dollar of employer cost.
I built a salary raise calculator at zovo.one/free-tools/salary-raise-calculator that shows the actual net impact of a raise after federal, state, and payroll taxes. It also compares your raise against inflation to show the real purchasing power change.
