Contract Inputs
Permanent Inputs
How this contract permanent calculator helps you decide
Choosing between contract work and a permanent role can feel confusing because each option pays differently and carries different risks. A contractor may earn a higher day rate, while a permanent employee often receives benefits, pension support, and more stability. This calculator gives you a practical, side-by-side annual comparison using your own assumptions.
What the calculator compares
The model estimates annual value for both paths:
- Contract path: day-rate revenue, minus business expenses, then adjusted by an effective tax rate.
- Permanent path: salary + bonus after tax, plus employer pension and non-cash benefits.
It also shows two useful conversion figures:
- The equivalent permanent salary needed to match your contract net value.
- The equivalent day rate required to match your permanent package value.
How to use it well
1) Be realistic about utilization
Contractors are rarely billable 52 weeks per year. Include expected gaps between clients, holidays, sick time, and training. For many professionals, 44–48 working weeks is more realistic than 50+.
2) Don’t ignore true contract costs
Expenses matter more than people think. Insurance, software licenses, accountants, equipment, commuting, and self-funded learning can reduce net income significantly.
3) Use effective tax rates, not headline rates
Effective tax rates are easier for planning. If you know your historical after-tax outcomes, use those percentages for better accuracy.
Important factors beyond the numbers
A purely financial answer is useful, but not complete. Your best choice also depends on lifestyle and career goals:
- Stability: permanent roles can reduce income volatility.
- Flexibility: contracting can provide more control over schedule and projects.
- Career growth: permanent roles may provide clearer promotion tracks and mentorship.
- Market risk: contractors may face tougher periods during hiring slowdowns.
- Personal preference: some people prefer variety; others prefer team continuity.
Quick interpretation guide
After calculating, focus on the annual difference and monthly difference. If one option is only slightly better financially, then quality-of-life factors may outweigh the money. If the difference is large, the financial case is much clearer.
As a rule of thumb, re-run this calculator every few months because rates, tax assumptions, and market demand can change quickly.
