Calculate Your Campaign Break-Even Point
Enter your advertising spend, average revenue per sale and profit per sale. Add optional campaign costs, expected sales or a profit target for a fuller profitability picture.
What Is a Campaign Break-Even Point?
A campaign break-even point is the moment a campaign has generated exactly enough profit from sales to cover everything it cost to run. It is expressed as a number of sales, the revenue those sales represent, and the ROAS required to get there.
Break-even is the honest floor for campaign performance. Anything below it is a subsidised campaign; anything above it contributes real profit to the business.
How to Calculate Campaign Break-Even
Start by totalling your fixed campaign costs: advertising spend plus any campaign-specific costs such as agency fees or creative production. Then work out how much profit one sale contributes, either from your gross margin percentage or from your variable cost per sale.
Divide total fixed campaign cost by contribution per sale and round up to the next whole sale. Multiply that by your average revenue per sale for break-even revenue, and divide break-even revenue by advertising spend for break-even ROAS.
Campaign Break-Even Formula
Core Break-Even Formulas
Total Fixed Campaign Cost
Advertising Spend + Other Campaign Costs
Contribution per Sale (Gross Margin)
Revenue per Sale × Gross Margin %
Contribution per Sale (Variable Cost)
Revenue per Sale − Variable Cost per Sale
Break-Even Sales
Total Fixed Campaign Cost ÷ Contribution per Sale
Break-Even Revenue
Break-Even Sales × Revenue per Sale
Break-Even ROAS
Break-Even Revenue ÷ Advertising Spend
Break-even sales are always rounded up to the next whole sale, because a partial sale is not possible. Variable costs are never added to fixed costs — they are already reflected in contribution per sale.

Campaign Break-Even Calculation Example
- Advertising Spend: ₹1,00,000
- Other Campaign Costs: ₹20,000
- Average Revenue per Sale: ₹5,000
- Gross Margin: 50%
- Expected Sales: 70
- Desired Profit: ₹1,00,000
- Total Fixed Campaign Cost: ₹1,00,000 + ₹20,000 = ₹1,20,000
- Contribution per Sale: ₹5,000 × 50% = ₹2,500
- Break-Even Sales: ₹1,20,000 ÷ ₹2,500 = 48 sales
- Break-Even Revenue: 48 × ₹5,000 = ₹2,40,000
- Break-Even ROAS: ₹2,40,000 ÷ ₹1,00,000 = 2.40x
- Profit at 70 Sales: 70 × ₹2,500 = ₹1,75,000 contribution, minus ₹1,20,000 = ₹55,000 estimated profit
- Sales Required for ₹1,00,000 Profit: (₹1,20,000 + ₹1,00,000) ÷ ₹2,500 = 88 sales
- Revenue Required: 88 × ₹5,000 = ₹4,40,000, a 4.40x ROAS

What Is Contribution per Sale?
Contribution per sale is the amount of money one sale leaves behind after its direct delivery costs. On a ₹5,000 order with a 50% gross margin, ₹2,500 is available to pay down advertising and other campaign costs.
It is the single most important number in break-even planning: the larger the contribution per sale, the fewer sales the campaign needs before it turns profitable.
What Is Break-Even ROAS?
Break-even ROAS is the return on ad spend at which a campaign stops losing money. It compares the revenue required to break even with your advertising spend, so it translates margin economics into a number you can set as a campaign target.
Other campaign costs are included when working out the required break-even revenue, but the ROAS denominator stays advertising spend, because ROAS conventionally measures revenue against media investment.
Break-Even ROAS vs Target ROAS
Break-even ROAS is the floor. Target ROAS is the goal you set above that floor to deliver a specific campaign profit — which is exactly what the target-profit section of this calculator produces.
Running campaigns at break-even ROAS is sometimes deliberate, for example when you are acquiring customers you expect to buy again. Doing it accidentally is how campaigns quietly consume budget.
How Gross Margin Affects Campaign Profitability
Margin decides how much of every sale is actually available to fund advertising. At a 50% margin, a ₹5,000 sale contributes ₹2,500. At a 25% margin it contributes ₹1,250 — so the same campaign costs require twice as many sales to break even.
This is why two businesses can report identical ROAS with completely different outcomes: one is profitable and the other is not.
How to Lower Your Campaign Break-Even Point
Increase average order value
Bundles, upsells and higher-value packages raise revenue and contribution per sale, which lowers the number of sales needed to break even.
Improve gross margin
Reducing product, fulfilment, shipping or payment costs increases contribution per sale without needing any extra traffic.
Reduce fixed campaign costs
Trimming avoidable production, tooling or setup costs directly reduces the total that sales have to cover.
Lift conversion rate
More sales from the same spend reduce the effective cost of each sale and move the campaign past break-even faster.
Cut wasted ad spend
Pausing non-converting placements, keywords and audiences lowers spend while keeping the sales that matter.

What is a campaign break-even point?
A campaign break-even point is the number of sales — and the revenue those sales represent — needed for a campaign to cover its costs. Below that point the campaign loses money; above it, every additional sale contributes profit.
How do you calculate break-even sales for a marketing campaign?
Add your advertising spend and any other fixed campaign costs, then divide that total by your contribution per sale. For example, ₹120,000 in campaign costs divided by ₹2,500 contribution per sale is approximately 48 sales. Always round up, because a partial sale is not possible.
What is contribution per sale?
Contribution per sale is the money left from one sale after the direct costs of delivering it. Using gross margin it is revenue per sale × gross margin percentage; using variable costs it is revenue per sale − variable cost per sale. That amount is what pays down your fixed campaign costs.
What is break-even ROAS?
Break-even ROAS is the required break-even revenue divided by advertising spend. It tells you the minimum return on ad spend needed before the campaign stops losing money based on your own cost and margin assumptions.
Why does gross margin affect break-even ROAS?
A lower gross margin leaves less contribution per sale, so more sales and more revenue are needed to cover the same campaign costs — which raises the break-even ROAS. High-margin businesses can be profitable at a much lower ROAS than low-margin ones.
Should I use gross margin or variable cost per sale?
Use gross margin when you already track it as a percentage across products. Use variable cost per sale when you know the specific per-order costs such as product cost, shipping, payment fees or commission. Both methods produce the same contribution per sale when they describe the same economics.
Can a campaign have a positive ROAS but still lose money?
Yes. ROAS compares revenue with ad spend and ignores product costs, fulfilment and other campaign costs. A 2x ROAS on a 30% margin product usually loses money, because the revenue generated does not cover the cost of goods plus the media spend.
How many sales do I need to reach a target profit?
Add your desired campaign profit to your total fixed campaign cost and divide by contribution per sale. For example, (₹120,000 + ₹100,000) ÷ ₹2,500 is approximately 88 sales, rounded up to the next whole sale.
What costs should I include in campaign break-even calculations?
Include advertising spend plus campaign-specific fixed costs such as agency fees, creative production, landing page development or campaign software. Per-sale costs such as product cost, shipping and payment fees belong in variable cost per sale or in your gross margin, not in fixed costs.
Why can actual campaign profitability differ from this estimate?
Real campaigns are affected by refunds, discounts, taxes, attribution gaps, changing acquisition costs, delivery and overhead costs not entered here. The output is an estimate based only on the values you provide.
