Platform presets use the Feb 2026 SST-inclusive all-in rate card (commission + programme + transaction fees) and exclude the RM 0.54 per-order support fee. Estimates only — confirm your category's current rates on the official Seller Centre. Rates last verified: 2026-07-20.
Margin first, ROAS second
The single most expensive mistake in TikTok and Shopee advertising is scaling campaigns by ROAS without knowing the breakeven. ROAS compares revenue to ad spend; your P&L runs on profit. Once platform fees (~19–20% in Malaysia after the Feb 2026 update), COGS and affiliate commission come out, the margin left over is what your ads are allowed to consume. The breakeven ROAS in the calculator above is that line — computed as revenue ÷ profit-before-ads.
A worked example
Sell at RM 100 with RM 35 COGS on TikTok Shop: platform fees take ~RM 19, leaving RM 46 before ads — a 46% pre-ads margin and a breakeven ROAS of ~2.2. Add a 15% affiliate commission and the pre-ads margin drops to 31%, pushing breakeven ROAS to ~3.2. Same product, same ads — very different scaling decision. Full reasoning in ROAS vs profit: why a 5x ROAS can still lose money.
Where estimates stop being enough
This tool models one order. A real store has hundreds of orders across categories, payment methods and campaigns — each with different actual fees. Inseller does this math on every real order from your connected stores, so you see net profit per order, per SKU and per live session without a spreadsheet. Start with the fee calculators for TikTok Shop and Shopee, or read how to calculate your real profit.
FAQ
How do I calculate breakeven ROAS?
Breakeven ROAS = revenue ÷ profit-before-ads, which is the same as 1 ÷ your margin before ads. If your margin before ads is 25%, breakeven ROAS is 4.0 — any campaign below 4.0 loses money even though the platform dashboard looks healthy.
Why can a 5x ROAS still lose money?
Because ROAS compares revenue to ad spend, not profit to ad spend. With thin margins after fees, COGS and affiliate commission, a 5x ROAS can sit below your breakeven. Margin decides, not ROAS.
What margin is realistic for Malaysian Shopee / TikTok sellers?
After ~19–20% platform fees, typical COGS of 25–45% and ads or affiliate on top, strong operators land at 15–25% net margin, and many sit at 5–15%. Below 0 is common when ads and affiliate are never allocated per order.
Is this calculator using real platform rates?
The TikTok Shop and Shopee presets use the Feb 2026 SST-inclusive all-in rate card (the same constants our profit engine uses for estimates). Your actual settlement can differ — always reconcile.
This calculator shows an estimate. Inseller connects your actual Shopee and TikTok Shop stores and shows the real number — net profit per order, per SKU and per live session, reconciled against actual settlement. Built by a seller running a real Malaysian store.
