UK workforce cost planner for Founders and Small and Medium-sized Enterprises (SMEs). Employer National Insurance (NI), Pension, Employment Allowance, Apprenticeship Levy — calculated correctly, not guessed in a spreadsheet.
The rate changed to 15% in April 2025 and the Secondary Threshold dropped to £5,000. Is your sheet current?
Someone joining in September costs 7/12ths of a full year — not full whack. Most sheets do not account for this.
Want to compare hiring 3 engineers vs 2 engineers + 1 contractor? That is a scenario, not another broken tab.
If you are budgeting workforce costs in a spreadsheet, this replaces it.
You are hiring fast and need to know what each role actually costs before you commit. You do not have an FP&A team — you are the FP&A team. You need a quick answer to "can we afford 3 more engineers this quarter?" without spending half a day in Excel.
You own the headcount budget and report to the board. You need scenario comparisons, multi-year projections, and PowerPoint-ready exports. You know the statutory rules but you are tired of maintaining the formulas. You want the NI, Pension, and Employment Allowance to just work.
The tool uses 2025/26 tax year rates, updated for 2026/27. Every calculation is transparent — click any employee to see the full working.

We were budgeting hires in a Google Sheet with hardcoded NI. The first time we used Headcount Agent we found we had been underestimating costs by 18%.
