03 / THE METHOD
Transparent, by design.
Make every fee visible
Platform and affiliate rates vary by market, category and agreement. This calculator never silently claims a universal official TikTok fee.
Know your break-even
Profit equals net sale price minus fixed variable costs and percentage fees. Break-even is the price at which that contribution equals zero.
OUR CORE FORMULA
profit = price × (1 − total fee rate) − fixed variable costsThis is contribution profit, not business-wide net profit. Fixed overhead, business income taxes, tax remittance, financing and costs not entered are excluded.
04 / QUESTIONS ANSWERED
Clarity, not guesswork.
Does this use official live TikTok Shop fee rates?+
No. Fees shown on first load are illustrative demo inputs, not official rates. Enter rates from your Seller Center for your specific country, product category, seller status and agreement. TikTok Shop terms can change.
How is break-even price calculated?+
The calculator divides your total fixed per-order variable costs by (1 − the sum of percentage fees). If combined fees are 100% or more, no finite positive break-even price exists under this model.
Does this include VAT, sales tax or income tax?+
No. Start from a net sale price excluding tax collected on behalf of a tax authority. You remain responsible for your applicable tax treatment. For country-specific tax treatment, consult a qualified professional.
Will my product numbers be stored?+
No calculator inputs are sent to our server. Calculation and CSV export happen in your browser. Hosting infrastructure may process basic technical requests; see our privacy page.
How do I use it for another country?+
Choose a currency from the Market menu, then enter local prices, costs and actual seller fees. Switching markets does not automatically convert values using live exchange rates or select official commission rates.
