Understanding the True Cost of Pay Decisions

Salary cost vs total employer cost

The salary you offer is only part of what it costs to employ someone. Employer National Insurance contributions, and any pension contributions, sit on top of gross salary and change the real cost of a hire or a pay decision. The Employer Cost Calculator estimates total annual employment cost from a gross salary, so you can see the full figure before deciding.

Employer NIC and other employment-cost considerations

Employer National Insurance contributions are calculated separately from employee deductions and add a real cost on top of gross salary that's easy to overlook when comparing offers or pay rises. Use the Employer Cost Calculator to see this alongside the salary itself, rather than working it out manually.

Comparing salary increases

A pay rise costs more to give than the headline increase suggests, once Employer NIC and any pension contribution on the extra salary are included. The Pay Rise & Salary Comparison Calculator compares a current salary against a new one, and the Employer Cost Calculator shows the total employment-cost effect of the increase.

Overtime and bonus cost considerations

Overtime and bonus payments also carry Employer NIC on top of the amount paid to the employee, so the cost of a bonus scheme or regular overtime is higher than the gross payments alone. Try the Overtime Calculator or the Bonus Calculator to see the employee's take-home effect, and read How Is Overtime Taxed? and How Is a Bonus Taxed? for the underlying rules.

Hourly versus annual pay

Roles paid by the hour and roles paid an annual salary aren't always easy to compare directly, especially across different contracted hours. The Hourly Wage Calculator converts between an hourly rate and an annual equivalent; see the Hourly Pay vs Annual Salary guide for where these comparisons can mislead.

Using WageOra's Employer Cost calculator

The Employer Cost Calculator brings the considerations above together in one place — enter a gross salary and it estimates the total annual cost of employing someone, including Employer NIC. The Salary & Take-Home Pay Calculator can show the employee side of the same figure, so you can see both views of one pay decision.

Pay decisions beyond salary

Salary and Employer NIC are only part of a pay decision. Pension contributions, other benefits, and working patterns such as full-time, part-time or flexible hours all affect what a role costs and how attractive it is. Where WageOra has verified salary information for an occupation, sourced from the Office for National Statistics, it's shown on that occupation's page — not every occupation has a published figure yet, so WageOra doesn't offer employer benchmarking across pay bands. See Salaries for what's covered so far, and Sources for where the underlying data comes from.

What WageOra doesn't provide

WageOra's calculators produce general estimates to help you understand the cost of a pay decision — they are not payroll, tax, legal or HR advice, and they don't replace professional payroll software, an accountant, or specific advice for your business. See How WageOra Works for how WageOra's figures are calculated.
