Enter your ad spend and the revenue it brought in to get your return on ad spend (ROAS). Add your profit margin to see your break-even ROAS, your real profit after costs and ads, and the ad budget you need for a revenue goal. Works for affiliate commissions and your own products.
Margin helper: if your revenue is affiliate commission, use 100% — you have no product cost, so the whole commission is yours before ads. For your own product, use your real margin. Tap an example, then replace it with your own numbers.
Planning estimate only. Assumes your ROAS stays the same as you spend more, which often isn’t true at larger budgets. Use revenue after refunds, and check ad-platform revenue against your own sales records.
Quick answer: Divide the revenue your ads brought in by your ad spend. For example, $2,000 of revenue from $500 of ads is a 4:1 ROAS (400%): every $1 spent brought back $4 in revenue — before product costs. To know if that’s profitable, compare it with your break-even ROAS: 1 ÷ your profit margin.
ROAS measures revenue, not profit. The calculator uses only the numbers you enter — no generic “good ROAS” targets.
ROAS = revenue ÷ ad spend
Break-even ROAS = 1 ÷ profit margin (as a decimal)
Profit = revenue × margin − ad spend
ROI = profit ÷ ad spend × 100
Most you can spend and break even = revenue × margin
Ad spend for revenue goal = goal ÷ ROAS
ROAS is often written as a ratio (4:1), a multiple (4×) or a percentage (400%). They all mean the same thing.
If you sell your own product with a 40% margin, you only keep $0.40 of each $1 of revenue before ads, so you need a ROAS of 2.5 just to break even. As an affiliate, the commission is already your share — there’s no product cost — so your margin is 100% and your break-even ROAS is 1.0. That’s why the same ROAS can be profitable for an affiliate and a loss for a store.
| Metric | Formula | What it tells you |
|---|---|---|
| ROAS | Revenue ÷ ad spend | How much revenue each $1 of ads brings in |
| ROI | Profit ÷ ad spend × 100 | How much profit each $1 of ads leaves you after costs |
Example values are only placeholders. Your result is only as accurate as the numbers you put in:
| Input | Where to find it | Tip |
|---|---|---|
| Ad spend | Meta Ads Manager, Google Ads, Pinterest Ads, TikTok Ads | Use the same dates as your revenue. |
| Revenue | Your affiliate dashboard, store or payment provider | Use revenue after refunds, and only from this campaign. |
| Profit margin | (Revenue − product, delivery and payment costs) ÷ revenue | Affiliates: use 100% if your revenue is commission. |
Ad platforms can count sales they only partly influenced. Check the revenue they report against your own sales records before trusting a ROAS figure.
$500 of ads brought $2,000 of revenue: a 4.00 ROAS. At a 40% margin your break-even ROAS is 2.50, and you keep $800 before ads — a $300 profit. You could have spent up to $800 on ads and still broken even.
$500 of ads earned $900 in commission: a 1.80 ROAS. The commission is all yours, so your margin is 100% and break-even ROAS is 1.00. Profit: $400, an 80% ROI.
If that $900 were sales of your own product at a 40% margin, you’d keep only $360 — a $140 loss at the same 1.80 ROAS. You’d need a ROAS of at least 2.50 to break even.
For $10,000 of revenue at a 4.00 ROAS, you’d need about $2,500 of ad spend. At a 40% margin that leaves $1,500 profit — if your ROAS holds as you scale.
Any ROAS above your break-even ROAS is profitable, and how far above it you need to be depends on the profit you want. Break-even ROAS is 1 ÷ your margin, so it varies a lot: 1.0 for affiliate commissions, 2.5 for a 40% margin product. There’s no single “good” number for everyone.
No. ROAS compares revenue with ad spend. ROI compares profit — after product and other costs — with ad spend.
Divide 1 by your profit margin as a decimal. A 40% margin gives 1 ÷ 0.40 = 2.5. A 100% margin (affiliate commission) gives 1.0.
100%, if the revenue you enter is your commission. The merchant has already taken their costs out, so the commission is yours before ad spend.
Standard ROAS only counts sales credited to the ads. Ads can also lead to later searches or visits that aren’t credited, so treat ROAS as an estimate and look at your total sales too.
No. It only changes the symbol shown. Enter all your amounts in the currency you choose.
