Raise Calculator Widget

Embed a pay raise calculator for salary negotiations and review season. Readers enter their current salary or hourly rate and a raise as a percentage or an amount, and see the new pay, how much more arrives each year, month and paycheck, and whether the raise beats inflation.

Recommended. A small script (what it does) sizes the widget to fit its content, loads it lazily and keeps it isolated in its own frame. Works in WordPress (Custom HTML block), Squarespace, Webflow, Shopify, Blogger, React / Next.js and plain HTML - anywhere a <script> tag is allowed.

How it works

A percentage raise multiplies current pay by one plus the rate; a fixed raise is added, per year for a salary or per hour for an hourly wage. Hourly pay is annualised at hours per week x 52 so the yearly difference is comparable: 1.50 more an hour at 40 hours is 3,120 a year. The yearly difference is divided by 12 for the monthly figure and by the number of paychecks - 12, 24, 26 or 52 - for the paycheck figure, all before tax. Inflation is handled with the exact relation real = (1 + raise) / (1 + inflation) - 1, not by subtracting one percentage from the other: a 5% raise in a year of 3% inflation is a 1.94% real increase, and a 2% raise against 4% inflation is a 1.92% cut in buying power, which the widget flags.

Calculation method

  • New pay = current x (1 + raise %), or current + raise amount
  • Yearly difference = raise x (1 for salary, or hours a week x 52 for hourly)
  • Per month = yearly / 12; per paycheck = yearly / paychecks a year
  • Real raise = (1 + nominal raise) / (1 + inflation) - 1

Worked examples

Annual review

Inputs: Salary 60,000; raise 5%; 26 paychecks; inflation 3%

Result: New pay 63,000.00 a year; 250.00 more a month; 115.38 per paycheck; real raise 1.94%

1.05 / 1.03 - 1.

Hourly raise

Inputs: 20.00 an hour; 40 h a week; raise amount 1.50; 52 paychecks; inflation 7.5%

Result: New pay 21.50 an hour; 3,120.00 a year more; new annual equivalent 44,720; real raise 0%

A 7.5% raise that only matches inflation.

Raise below inflation

Inputs: Salary 50,000; raise 2%; inflation 4%

Result: New pay 51,000.00; real raise -1.92%

Buying power falls despite the raise.

Limitations

  • Gross pay only - a raise can move you into a higher tax bracket or change benefit eligibility.
  • Uses one inflation rate for the whole year; your own cost of living may rise faster or slower.

Where publishers use it

  • Salary-negotiation guides showing what a 3% versus 5% offer is worth
  • Payroll and HR blogs during annual review season
  • Personal-finance sites explaining real versus nominal pay growth
  • Union pages comparing a pay offer with the latest inflation figure
  • Job boards helping hourly workers compare a raise with a new job
  • Teachers, nurses and civil servants checking a negotiated pay-scale uplift against inflation
  • Freelancers and contractors deciding how much to increase an hourly rate in January

Questions

Is a 5% raise with 3% inflation a 2% real raise?

Nearly: the exact figure is 1.05 / 1.03 - 1 = 1.94%. Simple subtraction overstates real gains slightly, and the gap grows with high inflation.

Which inflation rate should I enter?

Usually the latest 12-month consumer price index change for your country, such as the US CPI-U or the UK CPIH. The widget uses whatever rate you type.

How much more per paycheck is a 3,000 raise?

Before tax: 250 a month, 125 semi-monthly, 115.38 biweekly or 57.69 weekly. Take-home pay rises by less after income tax and contributions.

How is an hourly raise turned into a yearly figure?

Raise per hour x hours per week x 52. A 1.50 raise at 40 hours is 3,120 a year; at 25 hours it is 1,950.

Can I enter a pay cut?

Yes - a negative percentage or amount shows the reduction, as long as the new pay stays above zero.

Is it better to negotiate a percentage or an amount?

Employers budget merit increases as percentages, but an amount is concrete: on a 48,000 salary, a 4% merit increase is 1,920 a year or 73.85 per biweekly paycheck. Promotion bumps of 10-15% usually exceed the standard merit pool, and cost-of-living adjustments (COLA) track a price index instead.

How do raises compound over the years?

Successive raises multiply rather than add: three yearly 4% raises lift pay by 12.49% (1.04 cubed), not 12%, and a decade of 3% annual increments grows a salary by 34.39%.

Does a raise change retirement contributions?

Usually yes: pension or 401(k) contributions set as a percentage of salary rise with it. At a 6% contribution, a 3,000 raise adds 180 a year of saving, and any employer match grows too.

Why do raises vary between employees?

Many employers use a merit matrix: the raise depends on the performance rating and on where pay sits within the salary band, so someone already near the top of their range (a high compa-ratio) often gets a smaller percentage.
