Developer Rates Calculator — FAQs
Contractor vs permanent — which is cheaper?
Short engagements (<9 months): contractor wins — no recruitment fee (~20% of salary), no on-costs. Long-term: permanent is cheaper per day.
Why are agency rates double?
You're buying bench strength, PM cover and replacement guarantees — and the agency's margin on top of the dev's rate.
