Uitgebreide gids binnenkort beschikbaar
We werken aan een uitgebreide educatieve gids voor de Hourly to Project Rate Converter. Kom binnenkort terug voor stapsgewijze uitleg, formules, praktijkvoorbeelden en deskundige tips.
The Hourly to Project Rate Converter helps freelancers and consultants transition from time-based to value-based pricing by converting hourly rates into project-based fixed pricing that properly accounts for time buffer (project overrun risk), overhead (your business operating costs), and profit margin. Hourly billing has fundamentally limited upside — the only ways to increase income are working more hours or raising rates. Project-based pricing rewards efficiency: if you complete a project in 30 hours that you priced at 40 hours, you keep the savings as additional margin. The calculator outputs the recommended project rate and effective hourly rate. The pricing formula stacks three multipliers on top of base hours-times-rate. Time buffer (typically 20%) covers scope creep, communication overhead, and project overruns — without it, every unexpected complication eats into your margin. Overhead (typically 15%) covers your business operating costs: software subscriptions, tools, accounting, taxes, retirement contributions. Profit margin (typically 20%+) is the markup above costs that creates the wealth-building component of self-employment income. Without explicit profit margin, you're essentially working at break-even. Most beginning freelancers quote project rates equal to hourly × hours, leaving zero room for the inevitable overruns and overhead. This is why so many freelancers feel they're 'working too hard for too little money' — they're undercharging by 50-100% relative to the project rate that would actually compensate them fairly. The calculator helps make the math explicit and gives you confidence to quote rates that reflect true value delivery.
Project Rate = (Hourly × Hours) × (1 + Buffer%) × (1 + Overhead%) × (1 + Profit%)
- 1Step 1 — Enter your standard hourly rate
- 2Step 2 — Realistically estimate project hours (most underestimate by 30-50%)
- 3Step 3 — Set buffer percentage (20% covers typical scope creep)
- 4Step 4 — Set overhead percentage (15% covers tools, admin, taxes)
- 5Step 5 — Set profit margin (20%+ creates wealth-building component)
- 6Step 6 — Calculator outputs project rate and effective hourly rate

Should I always do project pricing?
Project pricing works best when scope is clear and you can deliver efficiently. Hourly works better for ongoing/unclear scope. Many freelancers offer both — project pricing for defined work, hourly for retainers and undefined consulting.
How do I know my real hourly rate?
Take desired annual income, divide by 1,000-1,200 billable hours (not 2,000 — freelancers have non-billable admin time). Example: $100k goal / 1,100 hours = $91/hr minimum hourly rate.
Pro Tip
For new project types, start with project pricing at 1.5-2× your hourly equivalent. As you learn actual time required, optimize. Most experienced freelancers earn 30-50% more on project pricing than equivalent hourly.
