About Work, Salary, and Time Tools

Understanding your real pay - and what employers are actually paying for your time - requires more than dividing an annual salary by 52. These work and salary tools handle the calculations that matter to workers, contractors, and employers alike: converting between hourly and annual rates, calculating overtime at 1.5x or 2x rates, working out the true cost of an employee including payroll taxes and benefits, and comparing pay across different contract types. Whether you are negotiating a job offer, setting a freelance rate, or checking whether a pay rise actually keeps up with inflation, fast and accurate numbers make a real difference.

Who uses these tools?

  • Job seekers comparing a salaried offer to their current hourly rate on an apples-to-apples basis
  • Freelancers and contractors setting a day rate that covers taxes, pension, and unpaid time
  • Employers calculating the true total cost of hiring a new employee including on-costs
  • Workers checking overtime entitlements and confirming payslip accuracy
  • HR teams comparing pay across part-time and full-time roles fairly

Frequently asked questions

How do I convert an hourly rate to an annual salary?
Multiply the hourly rate by the number of hours worked per week, then multiply by the number of working weeks in the year. For a standard full-time schedule: hourly rate x 40 hours x 52 weeks = annual salary. If you take unpaid holiday, subtract those weeks. A 25/hour rate equals roughly 52,000 per year at 40 hours per week with no unpaid time.
How is overtime pay calculated?
Most jurisdictions and employment contracts pay overtime at a premium rate - commonly 1.5x (time and a half) or 2x (double time) the regular hourly rate. The overtime threshold (the number of hours after which the premium kicks in) is typically 40 hours per week under US federal law, or 8 hours per day in some states and countries. Always check the rules specific to your employment contract and location.
What is the true cost of an employee beyond their salary?
Employers typically pay 20-30% more than an employee's base salary in additional costs: employer payroll taxes (Social Security and Medicare in the US, National Insurance in the UK), pension or retirement contributions, health insurance, paid holiday, and equipment. A 50,000 salary employee may cost 60,000-65,000 per year in total. This is why the true cost of employment matters for hiring decisions.
