Why "Rate Γ— Hours" Alone Underprices Your Work

The most common freelance pricing mistake is stopping at quote = hourly rate Γ— estimated hours. Real projects almost always include revision requests, extra communication, and surprises, so this calculator adds two layers. β‘  Revision/risk buffer: multiplies estimated hours by a cushion (typically 15–30%). β‘‘ Margin: covers business overhead β€” equipment, software, insurance, unbilled gaps between projects β€” plus profit (typically 10–30%). For example, at $50/hour for a 40-hour project, base labor is $2,000; a 20% buffer brings it to $2,400; a 15% margin makes the final quote $2,760. That looks 38% above base, but once two revision rounds and extra meetings land, this is what actually preserves your intended hourly rate.

Quoting Net vs Gross, and the Korean 3.3% Reference

Some freelancers think in take-home terms: "I want to net a specific amount." Withholding rules vary by country β€” in Korea, payers withhold 3.3% (3% income tax + 0.3% local tax) from individual freelance business income, so a β‚©2,760,000 quote pays out β‚©2,668,920; in the US there is typically no withholding on 1099 income but you owe quarterly estimated taxes including self-employment tax. Two things matter regardless of country: withholding is a prepayment, not your final tax β€” it reconciles at annual filing β€” and quotes should be set in gross terms with your local withholding treated as a cash-flow reference. To reverse a target net amount into a gross quote under a flat assumed rate, use the Gross-up Calculator alongside this tool.

Frequently asked questions

What revision buffer percentage should I use?
With a tight scope and contractually limited revision rounds, 10–15% is common; with fluid scope or many stakeholders, 25–30% is safer. Tracking the ratio of actual hours to quoted hours across past projects gives you a personal buffer rate that beats any rule of thumb.
Why add a separate margin β€” isn't it already in my hourly rate?
If your rate reflects pure working time, it excludes business overhead: equipment, software subscriptions, insurance, training, and unbilled time between projects. Margin recovers those costs plus profit at the project level. If you already built everything into your rate, simply set margin to 0%.
Is the 3.3% withholding my final tax?
No. It is a Korean prepayment mechanism for individual freelance business income; the actual tax is settled at the annual comprehensive income-tax filing (May), where deductible expenses may produce an additional payment or a refund. Other countries have entirely different rules β€” treat this line as a reference only.
