What ROAS do I need just to break even on ads?

ROAS stands for return on ad spend. It is simply the sales you get divided by the rupees you spent on ads. If you spend Rs 1,000 and get Rs 3,000 of sales, your ROAS is 3. Ad dashboards love to show this number, but a ROAS of 3 can be wonderful for one seller and a disaster for another. What matters is whether it clears your own break-even ROAS.

The formula

Break-even ROAS = selling price divided by contribution before ads.

Contribution before ads is the price minus product cost, shipping, packing and payment fee. In other words, the money one order leaves you before you pay anything to Instagram or Google. If you want a step by step method for that figure, read how to calculate contribution per order.

A worked example

Say a face-oil sells for Rs 1,000 and after product, shipping, packing and payment fee you keep Rs 400 per order before ads (illustrative).

Break-even ROAS = 1,000 divided by 400 = 2.5.

That means for every Rs 1 of ads, you need Rs 2.50 of sales just to cover the cost of the ad and not lose money. At exactly 2.5, ad spend per order is Rs 400, which eats the whole contribution.

See what ROAS 2.0 and 3.0 do

Imagine you spend Rs 10,000 on ads.

• At ROAS 2.0, sales are Rs 20,000, which is 20 orders. Contribution before ads is 20 x 400 = Rs 8,000. After the Rs 10,000 ad spend, you are Rs 2,000 down.
• At ROAS 2.5, sales are Rs 25,000, which is 25 orders. Contribution is Rs 10,000. You are exactly even.
• At ROAS 3.0, sales are Rs 30,000, which is 30 orders. Contribution is Rs 12,000. After ads you keep Rs 2,000.

So a move from 2.0 to 3.0 swings you from losing Rs 2,000 to gaining Rs 2,000 on the same spend. Small changes in ROAS matter a lot.

Why higher-contribution products can run on lower ROAS

If the same oil had Rs 600 contribution before ads, break-even ROAS would be 1,000 divided by 600, about 1.67. So a seller with healthy margins can bid and spend more aggressively than one with thin margins. Check your contribution before you copy a ROAS target from a friend's screenshot. Their product, shipping and packing are not yours.

What the dashboard does not tell you

• COD orders that get refused still count as sales in many reports, so the real ROAS is lower than shown. See returns and RTO, the numbers nobody tells you.
• Discount codes reduce your sale value but not your costs, which pushes your break-even ROAS higher.
• Repeat orders might be credited to the ad, but you could have won them anyway.

Using the number

Write your break-even ROAS on a sticky note. When you review a campaign, ask three questions.

• Is this campaign above the line? If yes, consider a modest increase in budget.
• Is it below the line but close? Test a new creative or a new audience before giving up.
• Is it far below? Pause it and look at price, offer or product page before spending more.

A break-even ROAS is not a target to aim for. It is the floor. Your aim is a ROAS comfortably above it, and a buffer for refusals, returns and the occasional bad week.
