How to use the profit & ROAS calculator
Know your numbers before you spend another dollar on ads.
Enter your per-order costs

Add your ad cost per sale
Take it from Meta, Google or TikTok Ads Manager — total spend divided by purchases.
Read your break-even ROAS
If your ads return less than this, you're paying to make sales. Aim for your target ROAS instead.
What is break-even ROAS?
ROAS (return on ad spend) is the revenue you make for every $1 spent on ads. A ROAS of 3 means $3 of sales for every $1 of ads. Break-even ROAS is the point where your ads pay for themselves and nothing more — no profit, no loss.
The mistake most stores make is using a "good ROAS" number from someone else. A 2.5 ROAS can be very profitable for a store with high margins and a loss for a store with thin ones. Your break-even point depends on your costs.
The formulas this calculator uses
Price − product − shipping − fees − otherPrice ÷ profit before ads= profit before adsPrice ÷ (profit before ads − target profit)How to improve your break-even ROAS
- Raise your average order value with bundles, volume discounts or a free-shipping threshold.
- Lower product cost by negotiating with suppliers once you have steady volume.
- Improve your conversion rate — a faster, clearer store turns the same ad clicks into more sales.
- Sell to past customers through email and SMS, where each sale costs far less than a new-customer ad.
Frequently asked questions
Quick answers to what people ask most.
What is a good ROAS for Shopify?
There is no single good ROAS. It depends on your margins. Work out your break-even ROAS with this calculator, then aim comfortably above it — that is your real target.
How do you calculate break-even ROAS?
Divide your selling price by your profit per order before ads. For example, a 50 price with 25 profit before ads gives a break-even ROAS of 2.0.
What is the difference between ROAS and CPA?
ROAS is revenue divided by ad spend. CPA (cost per acquisition) is ad spend divided by the number of sales. Break-even CPA is the most you can pay for one sale without losing money.
Should I include shipping and payment fees?
Yes. Shipping you pay for, card processing fees and packaging all come out of every order. Leaving them out makes your break-even ROAS look lower than it really is.
Does this calculator work for dropshipping?
Yes. Enter the supplier price as product cost and the supplier shipping as your shipping cost.
Is my data saved?
No. Everything is calculated in your browser and nothing is stored or sent anywhere.
