glowSeeding calculator: from samples to forecast GMV
Enter samples, post rate, views, CTR and conversion to see forecast GMV, seeding cost and return. Or start from a GMV goal and find how many samples to send.
Calculated for TikTok Shop Brazil: amounts in R$ (Brazilian format, comma as decimal separator).
What to expect
The math behind it
| Step | Formula | Example |
|---|---|---|
| Creators who post | samples × post rate | 100 × 20% = 20 |
| Attributed orders | posters × views × CTR × conversion | 20 × 3.000 × 1% × 3% = 18 |
| GMV | orders × average ticket | 18 × R$ 80 = R$ 1.440 |
| Return | (GMV − commission − seeding cost) ÷ seeding cost | (1.440 − 144 − 3.000) ÷ 3.000 = −0,57 |
The post rate, views, CTR and conversion defaults are examples with no published source. Use your real numbers: the result changes a lot with them.
How to use it
Pick “forecast GMV” to see what a batch of samples should return. Pick “find how many samples” to start from a GMV goal. Samples are rounded up.
What the calculator does not do
It ignores time to post, creators who post more than once, returns and TikTok Shop fees. For profit per sale, use the fee calculator. To choose who gets a sample, see Samples and shipping.
Formulas: creators who post = samples × post rate; orders = posters × views × CTR × conversion; GMV = orders × ticket. The post rate, views, CTR and conversion defaults are examples with no published source: use your own numbers.
Notice: Estimate, not a sales guarantee. The result changes with the numbers you enter.
