TikTok Shop Break-Even ROAS After the 6% Fee

A TikTok Ads dashboard ROAS is revenue ÷ ad spend. It is not profit. The number that decides whether you scale is break-even ROAS — selling price divided by what is left after the 6% US referral, creator commission, fulfillment, and COGS.

Those leftover dollars are the most you can spend to buy the order and still hit $0. The Break-Even ROAS Calculator is the same formula: set Platform Fee to 6.0%, Payment Processing to 0.0%, Payment Flat to $0.00, and Target Margin to 0. Fee dollars on this page come from the same tiktok-shop.ts file the TikTok Shop Fee Calculator already reads (defaults match SKU A).

The leftover is the ad budget

Break-even ROAS = price ÷ (price − referral − creator − fulfillment − COGS). Raise any of those four costs and the denominator shrinks, so the ROAS you must hold goes up. A 15% creator offer is 2.5× the 6% platform fee on the same paid price — it is not inside the referral line. For the rate ceiling itself, use the creator commission cost page. This page stops at what that leftover does to paid ads.

SKU A, self-ship, no creator. Scroll sideways on small screens. Add a creator % or swap ship for FBT and the right-hand number moves.

SKU A: $29.99, same defaults as the fee calculator

SKU A is $29.99 paid price, $8.00 COGS, $3.50 seller-fulfilled shipping. Referral is 6% = $1.80. Payment processing stays $0.00. Target margin is 0 — this table is true break-even, not a 10% profit overlay.

SKU A · $29.99 · $8.00 COGS · most-category 6%

Stack	Fulfillment	Creator	Leftover	BE ROAS	Max CPA
Self-ship, no creator	$3.50	$0.00	$16.69	1.80×	$16.69
Self-ship + 10% creator	$3.50	$3.00	$13.69	2.19×	$13.69
Self-ship + 15% creator	$3.50	$4.50	$12.19	2.46×	$12.19
FBT $3.58 + 15%	$3.58	$4.50	$12.11	2.48×	$12.11
FBT $8.00 + 15%	$8.00	$4.50	$7.69	3.90×	$7.69

Leftover = price − 6% referral − creator − fulfillment − COGS. BE ROAS = price ÷ leftover. FBT cells use fbtFeeRangeUsd ($3.58–$8.00), last verified 2026-10-01. Your rate-card tier may sit anywhere in that range — verify in Seller Center.

If the SKU is seller-fulfilled and you are not paying creators, the ads target is 1.80× — $16.69 of ad spend per order. If you add a 15% creator offer and land on the high FBT cell, leftover falls to $7.69 and the same ads now have to hold 3.90×. FBT alone (no creator) is 2.46× on this SKU; the creator line is what pushes the last row toward 4×.

SKU B: the $19.99 unit runs out of leftover

Same COGS band, more shipping drag, lower sticker. SKU B is $19.99, $8.00 COGS, $4.50 self-ship — the tighter pair from the creator-commission page.

SKU B · $19.99 · $8.00 COGS · $4.50 self-ship

Stack	Leftover	BE ROAS	Ads decision
Self-ship, no creator	$6.29	3.18×	Paid only if you can hold ~3.18×
Self-ship + 15%	$3.29	6.07×	Need efficient ads or cut the creator rate
FBT $8.00 + 15%	-$0.21	N/A	No room for ads — loss before spend

Same formula as SKU A. When leftover ≤ $0 the ROAS calculator prints “N/A (no room for ads)” — do not average that into a blended 3× target.

If A — $29.99, self-ship, no creator — the tool result tends toward 1.80× and you can test paid. If B — $19.99 plus a 15% creator offer plus high-end FBT — leftover is -$0.21 and the honest move is to raise price, cut the creator rate, or stay organic until the unit economics clear $0 before ads.

Reproduce both SKUs in the ROAS calculator

Open the Break-Even ROAS Calculator. Set Payment Processing to 0.0%, Payment Flat Fee to $0.00, Target Profit Margin to 0, Conversion Rate 2.5% if you want the CPC row.
SKU A: Selling Price $29.99, Product Cost $8.00, Shipping $3.50, Platform Fee 6.0%. Break-even ROAS should read 1.80×; Maximum CPA $16.69.
Add a creator offer by raising Platform Fee to 21.0% (6% + 15%). The hero should move to 2.46×. For FBT, leave that combined platform fee and set Shipping to $3.58 or $8.00 — 2.48× / 3.90×.

Frequently asked questions

How do I calculate break-even ROAS for TikTok Shop ads?

Break-even ROAS = selling price ÷ leftover dollars after every non-ad cost. Leftover = price − 6% US referral − creator commission − fulfillment − COGS. Payment processing is already inside the US referral (0.0% + $0.00 in this dataset), so do not add a second card fee. On the calculator-default $29.99 SKU with $8.00 COGS and $3.50 self-ship, leftover is $16.69 and break-even ROAS is 1.80×. Reproduce it in the Break-Even ROAS Calculator: Platform Fee 6.0%, Payment 0.0% + $0.00, Target Margin 0.

Does the 6% TikTok Shop referral fee include payment processing?

Yes for US sellers in this dataset. The official US schedule is a flat 6% on most categories (5% jewelry / pre-owned), and that line already includes payment processing. Set the ROAS calculator’s Payment Processing to 0.0% and Payment Flat Fee to $0.00. Adding a generic 2.9% + $0.30 on top double-counts a fee US Shop sellers do not pay separately. Confirm the live category rate in Seller Center — new-seller 30-day reductions are account-specific.

How do I add creator commission to the break-even ROAS calculator?

The ROAS tool has one Platform Fee field. Add the creator rate to the referral: 6% + a 15% creator offer = 21.0% in that box. On SKU A that moves leftover from $16.69 to $12.19 and break-even ROAS from 1.80× to 2.46×. Creator commission is a seller-set 1–80% input, not a TikTok fee-card line — verify the live Open / Target rate in Affiliate Center.

What break-even ROAS should I use if I fulfill with FBT?

Swap the shipping input for your FBT tier. This dataset’s FBT planning range is $3.58–$8.00 per unit. On SKU A with a 15% creator offer, the low FBT cell is 2.48×; the high cell is 3.90×. If leftover goes to $0 or below — SKU B at $19.99 + 15% + $8.00 FBT is -$0.21 before ads — the calculator should read N/A. Use the SKU’s rate-card tier from Seller Center, not the range midpoint.

Is jewelry / pre-owned a lower break-even ROAS than most categories?

Yes, by the referral gap only. Jewelry / pre-owned is 5% instead of 6%. On SKU A self-ship with no creator that is 1.77× versus 1.80×. FBT and creator commission still dominate the leftover. Confirm the product’s assigned category in Seller Center before you treat it as 5%.
