The most expensive mistake in freelancing is made on day one: taking your old salary, dividing by 2,080 hours, and quoting that. It feels rigorous. It's actually a ~50% pay cut with extra paperwork. This guide walks the real formula, the billable-hours reality that drives it, a worked example, and how to translate the result into day and project rates.
Key Takeaways
- Rate = (income + overhead + benefits + tax buffer) ÷ billable hours — every term matters.
- Billable hours ≈ 50–60% of your time. Plan on ~1,000/year full-time, not 2,080.
- You inherited your employer's costs: their tax share, your health insurance, equipment, software, and every unpaid vacation day.
- Quote project prices from your hourly floor, padded 20–50% for revisions and scope creep.
- Raise rates on new clients first — it's the zero-risk way to test the market.
The formula, term by term
1. Target income. What you want to keep before income tax — usually your old salary or better. Freelancers taking client risk, feast-famine cycles, and zero paid leave for their old salary are subsidizing their clients.
2. Overhead. Software subscriptions, equipment and its replacement cycle, insurance (liability, and health if you're in the US), accounting, coworking or home-office costs, marketing. For solo knowledge workers this typically runs $5,000–$15,000/year — small individually, rate-moving in total.
3. The employer costs you inherited. In the US, self-employment tax means you now pay both halves of Social Security/Medicare — an extra ~7.65% your employer used to cover, part of the full ~15.3% SE tax on net earnings. Add retirement matching you now fund yourself and the gap between employer-group and individual health premiums. The Quarterly Tax Calculator turns this into the four estimated payments the IRS expects.
4. Billable hours — the term everyone gets wrong. A 40-hour week does not produce 40 billable hours. Prospecting, proposals, calls that don't convert, invoicing, bookkeeping, learning, and the gaps between projects are real working time that no one pays for. Established-freelancer surveys put billable share at 50–60%; new freelancers run lower while building pipeline. With four weeks off across holidays and life: 48 weeks × 40 hours × 55% ≈ 1,050 billable hours.
Worked example: replacing an $80,000 salary
| Line | Amount |
|---|---|
| Target income | $80,000 |
| Overhead (software, gear, insurance, accounting) | $9,000 |
| Health insurance gap + self-funded retirement | $12,000 |
| Extra employer-side tax you now pay (~7.65%) | $6,100 |
| Total to earn | $107,100 |
| ÷ billable hours | 1,050 |
| Hourly floor | ≈ $102/hour |
That's the floor — the rate at which you match your old package. Market positioning, specialization, and demand sit on top of it. And two deductions still come off every invoice before the money is yours: payment processing (PayPal's Goods & Services fee is 2.99% + $0.49 — the G&S calculator shows exactly what you keep, and how to gross-up invoices so you net a clean number) and the 25–30% you should be setting aside for taxes.
Run your own numbers — the Freelance Rate Calculator does this full computation with your figures, including utilization and weeks off.
Hourly vs day rate vs project pricing
Derive everything from the hourly floor, then pick the packaging per engagement:
- Hourly — best while you're learning to estimate scope, and for open-ended maintenance/advisory work. Weakness: it punishes you for getting faster.
- Day rate — hourly × 7–8, standard for on-site work, workshops, and consulting blocks. Clients like the budget certainty; you like the guaranteed block.
- Project — estimated hours × hourly × 1.2–1.5 (the multiplier is revisions, scope creep, and estimation error — you will use it). This is where experienced freelancers out-earn their hourly rate, because efficiency becomes margin instead of a discount. Invoice cleanly with the Invoice Generator, and put payment terms and a revision cap in writing every time.
Raising your rate (you'll need this sooner than you think)
The market signal is simple: if every prospect says yes, you're underpriced. A healthy close rate on proposals is well under 100%. The low-risk playbook: quote the new, higher rate to all new clients first; after it's proven, move existing clients with 30–60 days' notice — attrition is usually far lower than feared, and losing the most price-sensitive client at a 20% higher rate is typically a raise, not a loss. Revisit the whole calculation yearly: overhead creeps, insurance rises, and your floor moves with them.
Frequently Asked Questions
What is the formula for a freelance hourly rate?
(Target annual income + business overhead + self-funded benefits + self-employment tax buffer) ÷ realistic billable hours. For most full-time freelancers billable hours land around 1,000–1,200 per year — roughly half a salaried year — which is why freelance rates look 'high' next to salaries but aren't.
Why can't I just divide my old salary by 2,080 hours?
Because as an employee, roughly 2,080 hours were all paid; as a freelancer only billable hours earn. Admin, marketing, proposals, invoicing, gaps between clients, holidays, and sick days now come out of your time unpaid — and your employer's share of taxes, insurance, and equipment comes out of your rate.
How many billable hours does a freelancer really have per year?
Surveys and time-tracking data consistently land at 50–60% of working time being billable for established freelancers. Working a normal 48-week year, that's about 960–1,200 billable hours — use 1,000 for planning and be pleasantly surprised, not underwater.
Should I charge hourly, daily, or per project?
Start hourly until you can predict scope, then move repeatable work to project pricing — it rewards you for being fast instead of penalizing you. Day rates suit on-site and consulting work. Whatever you quote, derive it from your hourly floor: a day = 7–8 hours, a project = estimated hours × 1.2–1.5 for revisions and scope creep.
How do payment fees and taxes change what I should charge?
US self-employment tax adds ~15.3% on net earnings on top of income tax, and payment processing (e.g. PayPal Goods & Services at 2.99% + $0.49) comes off every invoice. Build both into the rate — the calculator does — and set aside 25–30% of each payment for quarterly estimated taxes.
