Strong True ROAS. Your ads are generating healthy profit after all fees.

Quick Answer

True ROAS measures your actual return on ad spend after all TikTok Shop fees — commission (5-9%), transaction fees (2%), VAT (19-27%), affiliate cuts, COGS, and shipping. A seller seeing 5.0x ROAS in TikTok Ads might actually have only 2.1x True ROAS. This calculator reveals the gap.

Why Your TikTok ROAS Is Misleading

TikTok Ads dashboard calculates ROAS as Revenue ÷ Ad Spend. Simple, clean, impressive. But this number is a fantasy — it ignores every fee TikTok charges you on those sales.

For EU sellers, the reality is harsh. Platform commission takes 5-9%, transaction fees take 2%, VAT eats 19-27% (pass-through that inflates revenue numbers), and affiliate payouts can consume another 10-20%. By the time all fees are deducted, your “5x ROAS” might actually be 1.5x.

True ROAS accounts for every deduction. It answers the only question that matters: for every euro I spent on ads, how many euros of actual profit did I generate?

How to Calculate True ROAS

1. Enter your campaign numbers

Start with your total ad spend and the revenue attributed to those ads. Add the number of orders for accurate per-order fee calculations.

2. Select category and country

Choose your product category (commission rate varies from 5% to 6%) and your primary EU selling country (VAT rates range from 17% to 27%).

3. Add optional costs for full picture

For the most accurate True ROAS, add your COGS per unit, affiliate commission rate, shipping costs, and expected return rate in the Advanced Options.

What Is a Good ROAS for TikTok Shop EU?

Most sellers consider a 3x-5x ROAS as “good” — but that's naive ROAS. After all EU fees, you need a True ROAS of at least 3.0x for healthy profitability, 1.5-3.0x is marginal (you're barely covering costs), and below 1.5x means you're losing money on every ad euro.

Break-even occurs at exactly 1.0x True ROAS. In naive terms, that typically requires 2.0-3.0x depending on your fee structure and margins.

Frequently Asked Questions

What is ROAS and how do you calculate it?
ROAS (Return on Ad Spend) measures how much revenue you earn for every euro spent on ads. Basic ROAS = Revenue / Ad Spend. True ROAS goes further by subtracting all platform fees, VAT, COGS, and shipping before dividing by ad spend — giving you the actual return, not the inflated number.
What is a good ROAS for TikTok Shop?
A naive ROAS of 3x-5x is often cited as 'good', but this ignores TikTok's fees. After accounting for 5-9% commission, 2% transaction fee, VAT, and other costs, a 5x naive ROAS might actually be only 2x True ROAS. Aim for a True ROAS of at least 3x for healthy profitability.
Why is my true ROAS lower than what TikTok shows?
TikTok Ads dashboard calculates ROAS as Revenue / Ad Spend, ignoring all platform fees. Your true ROAS is lower because it accounts for commission (5-9%), transaction fees (2%), VAT (19-27% in the EU), affiliate payouts, COGS, and shipping costs that eat into your actual returns.
How do TikTok Shop fees affect my ROAS?
TikTok Shop fees can reduce your effective ROAS by 30-50%. For example, on €500 revenue: platform commission takes €30-45, transaction fees take €10, VAT takes €80-100, and shipping/COGS consume the rest. A 5.0x naive ROAS can become 1.5-2.5x True ROAS after all deductions.
What ROAS do I need to break even on TikTok Shop?
Break-even occurs at a True ROAS of exactly 1.0x — meaning your true profit (after all fees) equals your ad spend. In naive ROAS terms, you typically need at least 2.0-3.0x depending on your fee structure, product margins, and country-specific VAT rate.
How does VAT affect ROAS for EU sellers?
VAT significantly impacts EU seller ROAS because EU prices are VAT-inclusive. In Germany (19% VAT), roughly €16 of every €100 in revenue goes to VAT. In Hungary (27%), it's €21. This VAT portion is pass-through money that never becomes profit, so it inflates naive ROAS calculations.
Should I include COGS in my ROAS calculation?
Yes, for a complete picture. ROAS without COGS tells you if ads cover platform fees, but not if you're actually profitable. True ROAS includes COGS because the goal is understanding real profit per euro spent on ads — not just revenue minus fees.
How can I improve my ROAS on TikTok Shop?
Focus on: 1) Products with lower commission categories (jewelry at 5% vs others at 6%), 2) Reducing return rates (each return costs 20% of commission as admin fee), 3) Optimizing ad targeting to improve conversion rates, 4) Negotiating lower COGS with suppliers, 5) Selling in lower-VAT countries when possible.
What is the difference between ROAS and ROI?
ROAS measures revenue per euro of ad spend (e.g. 3.0x means €3 revenue per €1 spent). ROI measures percentage profit: ((Profit - Investment) / Investment) × 100. A 3.0x ROAS doesn't mean 200% ROI because fees and costs eat into that revenue. True ROI can be negative even with a 'good' naive ROAS.
How do affiliate commissions impact my ROAS?
Affiliate commissions (typically 10-20% on TikTok Shop) are one of the largest fee components and dramatically reduce True ROAS. A product with 15% affiliate commission, 6% platform fee, and 2% transaction fee loses 23% of revenue to fees alone — before VAT, COGS, and shipping.
