Start with commission per sale, not the headline percentage
A high commission percentage does not automatically make a product worth filming. Compare the amount you might receive per qualifying sale with the money and time you would spend testing it. The calculation below is a planning tool, not a prediction that you will get those sales.
For example, a fictional £20 commissionable order at 10% produces a £2 estimate before adjustments. If your sample and delivery cost £24, you would need 12 such sales with commission retained to cover that £24 cash outlay. That does not yet cover your time, other expenses or tax.
Check your own current TikTok Shop offer
TikTok’s UK Affiliate Commission and Payout Rules distinguish estimated commission from the final payout. Discounts and refunds can affect the final amount. Check the current offer and settlement details in your own creator account; a rate shown in a research snapshot is not a promise of what your next order will earn.
These examples use simplified, fictional commissionable amounts. Do not assume the displayed retail price is always the commission base. US creators should check their own market’s rules rather than apply UK payout conditions.
The simple sample-cost formula
Estimated commission per qualifying sale = commissionable amount × commission rate. Turn 10% into 0.10 before multiplying.
Sales to cover the planned cash cost = planned cash cost ÷ commission retained per sale, rounded up to a whole sale. If the commission per sale is zero, this calculation cannot produce a break-even target. If orders earn different amounts, add their actual retained commissions until they cover the cost instead.
| Fictional example | Calculation | Result |
|---|---|---|
| Sample plus delivery | £20 + £4 | £24 cash outlay |
| Commission per qualifying sale | £20 × 10% | £2 before adjustments |
| Sales to cover the sample | £24 ÷ £2 | 12 sales with £2 retained each |
| Lower commission scenario | £24 ÷ £1.50 | 16 sales with £1.50 retained each |
| Include £36 of time and other costs | (£24 + £36) ÷ £2 | 30 sales with £2 retained each |
A lower percentage can still mean more money per sale
Compare amounts as well as rates. In the fictional cases below, the product with the higher percentage earns less per qualifying order. This is not enough to choose a winner: price, audience fit, evidence, availability and the demonstration you can make still matter.
| Fictional offer | Commissionable amount | Rate | Estimated commission |
|---|---|---|---|
| Product A | £12 | 20% | £2.40 |
| Product B | £35 | 10% | £3.50 |
Write down the full cost before ordering
Use a small note or spreadsheet. Keep cash costs separate from your chosen value for your time, so you can see both the cash recovery target and the fuller cost of the test.
- Sample price and delivery you actually pay.
- Props, consumables or extra delivery needed for the demonstration.
- Any production or editing costs you choose to incur.
- Your time, if you want to include it in your decision.
- The current commission offer, its date and the exact product variant.
- Any sample-offer conditions; do not assume a sample will be refunded or that you will qualify for a free one.
Track settled results, not just views
After posting, record your own qualifying orders and commissions as they settle. Keep pending estimates separate from retained earnings. A refund or a changed order value may leave your estimate different from the final result.
A video’s views and a product’s total GMV cannot tell you whether you recovered your sample cost. Your own retained commissions and costs answer that question. For instance, eight retained commissions of £2 total £16: against a £24 sample outlay you are still £8 short, even if the video attracted plenty of attention.
Make the number a decision aid, not a sales target you must chase
Before spending, ask whether you can afford the sample even if the video generates no commission. A product that requires a high number of sales to recover its cost may be a poor first test for your budget. Do not spend more just to recover an earlier purchase.
Shortlist a product with a buyer question you can answer honestly in your own footage.

Research helps you decide what to investigate; it cannot guarantee orders.
