TikTok Shop Discount Profit Calculator

TikTok Shop vouchers reduce the buyer's final price. This model applies its selected referral-fee assumption to the resulting sale amount and does not add a separate processing rate. Voucher funding and fee basis can differ, so check Seller Center to confirm the promotion type before pricing.

Max safe discount = 1 − (break-even price / original price). Break-even = (product cost + shipping) / (1 − confirmed referral fee − affiliate commission%). A 6% referral assumption is only an example; use the account rate in Seller Center before approving a promotion.

Flash sales can drive volume and boost ranking, but consistently selling at thin margins trains the algorithm and buyers to expect low prices. Run flash sales on slow-moving inventory, not your best sellers. Always calculate post-discount profit before activating.

Original price $34.99, product cost $10, shipping $5, 10% affiliate commission. At full price: fees = $34.99 × 16% = $5.60, profit = $34.99 − $5.60 − $15 = $14.39 (41% margin). At 25% off ($26.24): fees = $26.24 × 16% = $4.20, profit = $26.24 − $4.20 − $15 = $7.04 (27% margin). The discount cuts profit per order by nearly half — worth it only if volume increases enough to offset.

It depends on the voucher type. Seller-funded vouchers reduce what you actually receive, and referral fees apply to the discounted amount. TikTok-funded vouchers (platform promotions) mean you're paid the full original price while TikTok absorbs the discount — check the voucher type in Seller Center before assuming a promotion is cutting into your margin.

On both platforms, transaction fees are typically calculated on the post-discount price the buyer actually pays. Etsy sellers face a higher fee floor (~9.5–10% combined) even before a discount, so the same percentage-off discount cuts more deeply into Etsy margins than into TikTok Shop's 6% base fee. TikTok Shop's affiliate commission is the bigger lever to watch when stacking a discount on top of creator-driven sales.
