Why you don't keep 100% of your raise

Your raise is taxed at your marginal rate — the rate applied to your highest dollars of income. Even though your effective rate (taxes ÷ total income) is lower, each new dollar from your raise is taxed at the top bracket you've reached. For example, if your marginal federal rate is 22.0%, every extra dollar of your raise loses that share to federal taxes alone — before state taxes and FICA. That's why raises always feel smaller than advertised.
