What this free calculator shows you

Most paid media conversations stop at ROAS. That number tells you how much revenue came back, but it does not tell you how much of that revenue is actually profit after fulfillment costs, or how much of your budget was spent on clicks that never converted.

This simulator runs your numbers through three scenarios at once: conservative, baseline, and aggressive. You set your monthly ad budget, cost per click or CPM, conversion rate, order value or client lifetime value, and gross margin. The output shows gross profit, break-even ROAS, net yield, and pipeline waste side by side.

The profit curve below the cards shows what happens when you scale spend up or down. Past a certain point, platforms charge more per click and audiences get harder to convert. The curve accounts for that so you are not planning growth on a straight line that does not exist in the real world.

Use it before you raise budget, pitch a CFO, or walk into a QBR. It is free, runs in your browser, and does not require an account.

Who this calculator is for

We built this for the same people we work with on paid accounts: in-house media leads, agency buyers, and founders who need to defend budget decisions with math, not optimism. If you run Google Ads, Meta, LinkedIn, or CTV and want to know whether scaling spend actually makes money, start here.

Common questions about ROAS and paid media profit

Straight answers on break-even ROAS, pipeline waste, and how to read the numbers this calculator produces.

Is there a free ROAS calculator for Google Ads?
Yes. This tool is free and runs in your browser with no account required. Enter your monthly ad budget, cost per click or CPM, conversion rate, and gross margin. It calculates ROAS, gross profit, break-even ROAS, and pipeline waste across three performance scenarios so you can see a realistic range before you commit more budget.
How do I calculate break-even ROAS?
Divide 1 by your gross margin. If your gross margin is 40%, your break-even ROAS is 2.5x. That is the minimum return on ad spend required to cover fulfillment costs before you lose money on the campaign. Anything above that number is profit. Anything below it means you are paying to lose margin.
What is pipeline waste in paid media?
Pipeline waste is the portion of your ad budget spent on clicks that did not convert. Every campaign has it. Even profitable accounts lose money on traffic that bounces, compares, or leaves before buying. Knowing that number tells you whether your problem is traffic cost, conversion rate, or both.
What is a good ROAS for paid search?
It depends on your gross margin and what you are selling. A 3x ROAS sounds strong until your margin is 25%, which means you need 4x just to break even. High-ticket B2B with long sales cycles often accepts a lower front-end ROAS because lifetime value carries the account. Low-margin ecommerce needs a higher ROAS to stay profitable. Use break-even ROAS as your floor, not industry averages.
What is net yield on ad spend?
Net yield is gross profit divided by total ad spend, expressed as a percentage. ROAS measures revenue against spend. Net yield measures actual profit against spend. A campaign can show strong ROAS and still lose money if margin is thin. Net yield above 100% means your ad spend is fully recovered in profit with money left over.
Why does profit drop when I increase ad spend?
Platforms do not sell unlimited high-intent traffic at a fixed price. As spend rises, you exhaust your best audiences first. Cost per click goes up, click quality drops, and conversion rates fall. The profit curve in this simulator models that pressure so you can see where scaling stops making financial sense instead of assuming linear growth.
Can I use this for Meta, LinkedIn, or CTV campaigns?
Yes. Switch between cost per click and CPM cost basis depending on how you buy media. Enter your click-through rate when using CPM. The math works the same: budget divided by traffic cost gives you clicks, clicks times conversion rate gives you conversions, conversions times order value or lifetime value gives you revenue.

How the calculator works

This calculator projects how paid media profit changes as budget, traffic cost, and conversion rate move. It is built for operators who need numbers before a budget meeting, not a sales pitch.

  1. Enter your monthly ad budget, unit value, cost basis, conversion rate, and gross margin.
  2. The calculator runs three scenarios at once: conservative, baseline, and aggressive conversion assumptions.
  3. Review gross profit, ROAS, break-even ROAS, net yield, and pipeline waste in each scenario.
  4. Use the profit curve to see how returns change as spend scales up or down from your current budget.

Key formulas

Break-even ROAS equals 1 divided by gross margin. Pipeline waste is ad spend consumed by clicks that did not convert. Net yield equals gross profit divided by monthly ad spend. ROAS equals gross revenue divided by monthly ad allocation. The profit curve applies scaling pressure to conversion rate and cost per click as budget moves above or below the current allocation.
