A pay raise increases your compensation by a percentage of your current salary. Whether it comes from an annual review, promotion, or job change, understanding the full impact of a raise helps you make informed career and financial decisions. Even small percentage differences compound significantly over a career.

The formula is: New Salary = Current Salary x (1 + Raise% / 100), or equivalently, Raise Amount = Current Salary x Raise% / 100. To convert to an hourly rate: Hourly Rate = Annual Salary / (Hours per Week x Weeks per Year). The standard denominator for full-time work is 2,080 hours (40 hours x 52 weeks).

For example, an 8% raise on a $65,000 salary produces a raise amount of $5,200, bringing the new salary to $70,200. Monthly pay increases from $5,416.67 to $5,850, a gain of $433.33 per month. The hourly rate rises from $31.25 to $33.75 based on a 2,080-hour work year. When negotiating, remember that this higher base also increases future percentage raises and retirement contributions.
