This calculator helps you quickly determine the impact of a pay rate increase. Whether you've received a raise, are negotiating a new salary, or are simply curious about the financial implications of a higher hourly wage, this tool provides clear insights. It calculates both the absolute increase in your hourly pay and the percentage boost to your income, as well as projecting your new annual earnings based on a standard full-time work schedule.
How the Calculation Works
The calculator uses straightforward formulas to provide accurate results:
Increase Amount Per Hour: This is the simple difference between your new hourly rate and your current hourly rate.
Increase Amount = New Hourly Rate - Current Hourly Rate
Percentage Increase: This shows how much your pay has increased relative to your original rate, expressed as a percentage.
Percentage Increase = (Increase Amount / Current Hourly Rate) * 100
New Annual Income: This estimates your yearly earnings by multiplying your new hourly rate by the standard number of working hours in a year (typically 40 hours/week * 52 weeks/year = 2080 hours).
New Annual Income = New Hourly Rate * 2080
