How to read your result
Actual ROAS reports past performance. It does not show whether that performance was profitable.
Break-even ROAS is your minimum before overhead. A campaign below it loses contribution profit on the first order.
Target ROAS includes your chosen net margin, giving your media team a more useful operating target.
ROAS formulas
ROAS = ad revenue ÷ ad spend
Break-even ROAS = 1 ÷ contribution margin rate
Max CPA = contribution/order − target profit/order
For business decisions, also account for salaries, tools, warehousing, taxes, returns, and repeat purchase value.
ROAS calculator FAQs
How is ROAS calculated?
ROAS equals revenue attributed to advertising divided by advertising spend. If ads generate ₹400,000 from ₹100,000 of spend, ROAS is 4.0x or 400%.
What is break-even ROAS?
Break-even ROAS is the revenue-to-ad-spend ratio at which contribution profit after product, fulfillment, payment, and advertising costs is zero. It is calculated as 1 divided by contribution margin rate.
What is a good ROAS for ecommerce?
A good ROAS is one that exceeds your break-even ROAS and leaves your required profit. The right number depends on gross margin, average order value, returns, overhead, and customer lifetime value.
Does this calculator include GST and returns?
Not automatically. Enter revenue net of taxes and refunds, or include expected return and tax impact in your costs for a more conservative result.
