Break-Even ROAS: Formula, Calculator and Examples for Indian D2C Brands

Most brands judge their ads by one number: ROAS. A 2x or 3x on the dashboard feels like a win. But ROAS only compares revenue with ad spend. It says nothing about what you spent to make, pack, ship and sometimes take back the product.

That is why every brand needs one more number before it spends another rupee on ads: break-even ROAS. This guide shows you how to calculate it the right way for a growing brand (GST in India, VAT in the UK, EU and Gulf), with a free calculator and a full worked example.

What is break-even ROAS?

Break-even ROAS is the return on ad spend at which a campaign makes exactly zero profit. Above it, every order makes you money. Below it, every order loses money - even if the ROAS still looks "positive" in Meta Ads Manager or Google Ads.

Think of it as the floor. Any campaign that sits below the floor for long is burning cash, no matter how good the revenue number looks.

Break-even ROAS vs target ROAS

The two are often mixed up, so here is the difference in one line each:

• Break-even ROAS - the ROAS where profit is zero. Your pause line.
• Target ROAS - the ROAS you want, so each order leaves a profit you are happy with. Your scaling line. It is always higher than break-even.

The break-even ROAS formula

The basic formula is simple:

"Profit per order before ad spend" is what is left from one order after every cost except ads. It is also your maximum CPA - the most you can pay in ads for one sale before you start losing money.

If you know your contribution margin as a percentage, there is an even quicker version: break-even ROAS = 1 ÷ margin. A 40% margin means a break-even ROAS of 1 ÷ 0.40 = 2.5x.

How to calculate break-even ROAS step by step

The formula is easy. Getting the inputs right is where most brands go wrong. Follow these four steps.

Step 1: Remove GST from your selling price

Meta and Google record the price your customer paid. In India that price includes GST, and in the UK, EU and Gulf it includes VAT. But that tax goes to the government, not to you. So when you work out profit, use the price without GST.

For a ₹999 product in the 18% GST slab, your real revenue is ₹999 ÷ 1.18 = ₹846.61. Check the GST rate for your product's HSN code - after the September 2025 GST changes most goods sit in the 5% or 18% slab.

Step 2: Add up every cost per order

List every cost that happens because one order happened. Leave out ads for now.

• Product cost - manufacturing or purchase cost of the item (COGS).
• Packaging - box, filler, labels, inserts.
• Payment cost - payment gateway fee on prepaid orders, or the COD fee your courier charges.
• Forward shipping - what you pay the courier to deliver.

Costs most brands forget

Discounts and coupon codes, free gifts in the box, marketplace or app fees per order, and customer support time all eat into the same margin. If you run a "flat 20% off" sale, your break-even ROAS for that period goes up - recalculate it before the sale starts.

Step 3: Adjust for returns and RTO

This is the step almost everyone skips. When a COD order is refused (RTO) or a product is returned, you usually pay forward shipping and reverse shipping, and you earn nothing. On COD-heavy stores in India and the Gulf, RTO rates of 15-25% are common, so ignoring them can make a losing campaign look profitable.

Use your real return/RTO rate from the last 60-90 days. If the product comes back resellable, you only lose the shipping. If it comes back damaged, add the product cost to your loss per return too.

Step 4: Divide your price by profit per order

Profit per order before ads = (delivered share of orders × margin on a delivered order) − forward shipping on every order − reverse shipping on returned orders. Then divide your full selling price (with GST, because that is what the ad platform reports) by this number.

Worked example: a ₹999 face serum

How forgotten costs change the answer

Now see how much each "forgotten" cost moves the answer for the same product:

The owner who thinks the break-even is 1.73x will happily run a campaign at 2.4x and believe it is profitable. In reality, every order from that campaign loses money. On ₹10,00,000 a month of spend, that campaign loses about ₹1,79,000 a month.

How to use break-even ROAS in your ad accounts

Set your pause rule on break-even, not on a round number

"Pause anything under 2x" sounds sensible, but if your break-even is 2.92x it lets losing campaigns run. Give a new campaign enough time and data to learn (usually 5-7 days), then pause or fix anything that stays below break-even.

Set your target ROAS for scaling

Decide how much profit you want per order. If you want ₹100 profit on the serum above, your max CPA drops to ₹341.62 − ₹100 = ₹241.62, and your target ROAS becomes ₹999 ÷ ₹241.62 = 4.13x. Scale campaigns that hold above this line.

Use max CPA inside Meta and Google

Your max CPA is useful on both platforms. In Google Ads it is the ceiling for a Target CPA bid. In Meta Ads you can use it as the upper limit for a cost-per-result goal. Never set a bid goal above your break-even max CPA.

Remember repeat customers - but carefully

If customers reorder, a first order at break-even can still be profitable over time. That is a valid strategy, but only if you have real repeat-rate data. Until then, judge first-order campaigns against break-even ROAS.

Common break-even ROAS mistakes

• Using the price with GST or VAT as revenue. It makes every margin look about 15% better than it is in the 18% slab.
• Ignoring RTO on COD orders. The single biggest reason "profitable" campaigns lose money in India and the Gulf.
• Calculating once and never again. Price changes, sales, courier rate hikes and new products all change the number.
• Using one blended number for very different products. A ₹499 product and a ₹2,499 bundle have very different break-even points. Calculate per product or per campaign.
