Salary Increase Calculator
Calculates your new salary after a percentage-based pay rise. Ideal for employees evaluating a raise offer or HR teams modeling payroll cost changes across a team.
About this calculator
A percentage salary increase applies a proportional uplift to current pay. The formula is: New Salary = current_salary × (1 + increase_percentage / 100). The term (1 + increase_percentage / 100) acts as a multiplier — a 5% raise uses a multiplier of 1.05, a 10% raise uses 1.10, and so on. This approach ensures the raise is compounded on the full base salary rather than calculated separately and added. Understanding this formula matters because a 3% cost-of-living adjustment on a $50,000 salary adds $1,500, but on a $120,000 salary it adds $3,600 — the same percentage delivers very different dollar outcomes. HR teams use this calculation to model total payroll impact when applying across-the-board raises, while employees use it to verify offer letters and negotiate informed counteroffers.
How to use
Suppose your current salary is $72,000 and your employer offers a 6% merit increase. Enter 72,000 in Current Salary and 6 in Increase Percentage. The calculator computes: New Salary = 72,000 × (1 + 6 / 100) = 72,000 × 1.06 = $76,320. Your annual pay rises by $4,320, which works out to $360 more per month before tax. If you then receive a further 4% raise the following year, you would enter 76,320 as your new current salary, and the process repeats — showing how raises compound over time.
Frequently asked questions
What is a good salary increase percentage for a merit raise in 2024?
Most organisations budget merit increases of 3–5% for solid performers in a typical year, with top performers receiving 6–10% or more. In high-inflation periods, cost-of-living adjustments (COLA) of 3–4% are added on top of merit increases. Industry and role matter significantly — tech and healthcare often see higher average increases than retail or non-profit sectors. Benchmarking your raise against published compensation surveys from sources like SHRM or Mercer helps you assess whether an offer is competitive or below market.
How does a salary increase affect take-home pay after taxes?
A salary increase raises your gross pay, but the net (take-home) gain is smaller because a larger portion of your income may be taxed at a higher marginal rate. In progressive tax systems like the US, only the income above each bracket threshold is taxed at the higher rate — a common misconception is that the entire salary is taxed at the new rate. For example, a $5,000 raise in the 22% federal bracket costs roughly $1,100 in additional federal tax, leaving about $3,900 more per year. State taxes, Social Security, and Medicare contributions further reduce the net amount.
How is a salary increase different from a cost-of-living adjustment?
A merit or performance-based salary increase rewards individual contribution and is typically discretionary, varying by employee based on performance reviews. A cost-of-living adjustment (COLA) is applied uniformly to all employees to offset inflation and maintain purchasing power — it is not tied to individual performance. Both use the same mathematical formula, but their purpose and negotiability differ. Employees should track both separately: a 3% COLA in a 4% inflation environment is effectively a pay cut in real terms, even though the nominal salary increased.
