How do I calculate percentage increase in salary?

Subtract your original salary from your new salary to find your total dollar increase. Then divide that dollar increase by your original salary and multiply by 100. Formula: ((New Salary - Old Salary) / Old Salary) × 100.

What is a typical percentage increase for a pay raise?

Annual cost-of-living adjustments (COLA) typically range between 2% and 3.5%. Performance raises generally fall between 4% and 7%, while internal promotions usually yield an 8% to 15% salary increase.

How are taxes calculated on a percentage salary increase?

Any income earned through a salary increase sits in your highest federal income tax bracket. Your employer calculates automated withholding formulas that apply marginal tax rates plus standard Social Security and Medicare FICA deductions.

Does a 10% salary increase equal a 10% increase in take-home pay?

No. Because incremental earnings are taxed at top marginal rates, your net take-home pay percentage increase will almost always be slightly lower than your gross salary percentage increase.

How to Evaluate Your Salary Increase Percentage

Whether you received a standard 3% cost-of-living bump or negotiated a 12% promotion raise, translating that percentage into actual paycheck dollars requires looking at marginal tax rates.

Compute Gross Difference

An 8% raise on a $70,000 salary equals a $5,600 annual gross boost ($215.38 per bi-weekly paycheck).

Deduct Marginal Taxes

Marginal federal brackets (e.g. 22%) and FICA (7.65%) immediately deduct roughly 30% of that new cash boost.

Verify Checking Deposit

Your actual net checking deposit bump will likely be around $150 bi-weekly rather than the gross $215.
