Cost assumptions
TeamCalc uses UK 2025/26 tax rates and sensible defaults for overhead costs. You can customise these to match your organisation's actual figures.
Default assumptions
| Parameter | Default | Notes | |---|---|---| | Employer NI rate | 15% | Above secondary threshold (£5,000 for 25/26) | | Employer NI threshold | £5,000 | Annual secondary threshold | | Pension contribution | 5% | Employer contribution rate | | Benefits allowance | £2,000/year | Health, L&D, perks | | Equipment cost | £1,500/year | Amortised hardware cost | | Office cost | £4,000/year | Per-desk cost (set to £0 for remote) | | Recruitment fee | 15% of salary | Amortised over expected tenure | | Average tenure | 2.5 years | Used for recruitment amortisation | | Management overhead | 10% | Manager time per report | | Working days | 230/year | Used for contractor day rate calculation |
Customising assumptions
Visit Scenarios → Assumptions to adjust any parameter. Changes apply globally to all cost calculations in your workspace.
Common adjustments:
- Set office cost to £0 if your team is fully remote
- Increase pension to 8–10% if you offer enhanced contributions
- Adjust recruitment fee based on whether you use agencies (20%+) or hire directly (5–10%)
- Lower management overhead for senior/staff roles who need less oversight
Per-scenario assumptions
When building custom scenarios, you can override assumptions for that specific scenario without affecting your base team calculations.
