Two layers most calculators skip
A freelancer's real take-home goes through two separate cuts: the platform fee (if you work through Upwork, Fiverr or a similar marketplace) and then tax on whatever's left after business expenses. Most calculators only handle one layer. This one runs both, in order, so the final number is what you'd actually see land in your bank account.
The order matters
- Platform fee comes off the gross first — it's not a tax-deductible reduction of your income, it just never reaches you.
- Business expenses reduce what's left to get your taxable net profit.
- Self-employment tax or Class 4 National Insurance applies to that net profit.
- Income tax applies last, after the relevant deductions.
Where this differs from the Creator Tax tool
The Creator Tax & Deduction Estimator is built around platform-paid content income (OnlyFans, Twitch, Patreon). This tool adds a proper platform-fee step for marketplace freelancers — Upwork and Fiverr — before applying the same tax logic.
The same $70,000 through three routes (US, single filer)
With $6,000 of business expenses, here is what $70,000 of gross income leaves you after platform fees, self-employment tax and federal income tax. State tax is not included.
- Direct clients (no platform fee): net profit $64,000, take-home about $50,000 a year, or $4,167 a month.
- Upwork at a 10% fee: net profit $57,000, take-home about $44,769 a year, or $3,731 a month.
- Fiverr at 20%: net profit $50,000, take-home about $39,539 a year, or $3,295 a month.
What a platform fee really costs after tax
A 10% Upwork fee on $70,000 is $7,000. But your take-home falls by only about $5,230, not $7,000, because the fee also reduces your taxable profit. On Fiverr at 20%, the headline cost is $14,000 and the take-home drop is about $10,461. This is why the calculator applies the platform fee first and the tax afterwards, and why comparing headline percentages alone is misleading.
A UK comparison
For a UK freelancer with £70,000 of gross income and £6,000 of expenses, direct clients leave about £48,431 after income tax and Class 4 National Insurance. Through Upwork at 10%, take-home is about £44,371. The same effect applies: the platform fee costs less after tax than its headline amount.
How much to set aside
In the US direct-client example, self-employment tax plus federal income tax comes to about 22% of net profit. Through Upwork at 10%, it is about 21%. Add your state tax on top, and a 25–30% set-aside is a sensible starting point. Move that money into a separate account whenever a payout arrives, so a tax bill never feels like a surprise.
Turning the result into a budget
- Take the monthly take-home figure from the calculator, not your gross income.
- Subtract fixed costs such as rent, food and insurance.
- Decide a monthly amount for savings, and keep an emergency fund of a few months of expenses.
- If what remains is too small, return to the hourly rate calculator and raise your rate rather than working more hours.
What this estimate leaves out
State tax, the US 20% qualified business income deduction, additional Medicare tax, credits, Scottish rates, student loans and pension contributions are not included, so your real figure may differ. The methodology page lists every formula and source, and the tax guide explains payment deadlines in both countries.
