Raise Calculator

A percentage raise multiplies your current base salary by (1 + raise ÷ 100) to produce the new annual figure. The difference between new and old salary is your gross annual increase — divide by 12 for the monthly bump before any taxes or deductions. This covers base salary only; bonuses, equity grants, and one-time awards are separate line items on total compensation statements.

Employers express raises differently. Some quote a flat percentage of base pay effective on a specific date; others give dollar amounts ("$4,000 increase") that you can convert to a percentage by dividing the increase by current salary. Cost-of-living adjustments (COLAs) tied to CPI work the same mathematically but may apply across an entire workforce on a fixed schedule. Merit pools sometimes cap individual raises even when company performance is strong.

The gross increase overstates what you feel in your wallet. Federal and state taxes, FICA, and benefit contributions all apply to the higher salary — so a 5% raise rarely produces a 5% jump in take-home pay. Use our paycheck calculator with an updated gross and your typical deduction percentage to estimate net impact. Pre-tax 401(k) contributions absorb part of a raise before it hits taxable income, further shrinking visible net gains.

Promotion raises often combine a title change with a larger percentage than annual merit increases. When comparing an internal promotion to an external offer, convert both to total compensation including bonus targets, equity, and benefits — not just base salary after raise. External offers may include signing bonuses that a simple percentage raise on current base does not capture.

Negotiation context matters. Knowing that a 5% raise on $72,000 adds $3,600 annually ($300 per month gross) gives you a concrete anchor when discussing counteroffers. If inflation runs higher than your raise percentage, real purchasing power may still decline even though nominal salary rose. BLS Consumer Price Index data helps compare your raise to broad inflation trends, though personal inflation depends on your spending mix.

Mid-year effective dates prorate the first-year cash impact. A 5% raise starting July 1 on a calendar-year salary means half the year at the old rate and half at the new — first-year gain is roughly half the full annual increase shown here. HR systems usually adjust per-paycheck amounts automatically, but annual planning should use prorated figures when the raise is not January-effective.

Worked example with defaults: current salary $72,000 with a 5% raise. New salary = $72,000 × 1.05 = $75,600. Annual increase = $3,600. Monthly gross increase = $3,600 ÷ 12 = $300 before withholding. At a 25% all-in deduction rate, net monthly gain is about $225 — useful when comparing the raise to a $250/month subscription or childcare cost increase.

Results are planning estimates, not guarantees of future pay or tax advice. Employers may prorate raises mid-year, cap merit pools, or adjust benefits simultaneously. Confirm final numbers with HR and refer to IRS guidance on updating Form W-4 when salary changes materially. Stock compensation and deferred bonuses follow separate vesting schedules not reflected in base-salary raise math.
