Free marketing ROI & ROAS calculator

This free tool — built by a Singapore digital marketing agency — turns your spend and revenue into the four numbers that actually decide whether a campaign is working: ROAS, marketing ROI, cost per acquisition and, if you add your margin, your true gross profit and break-even ROAS. It runs entirely in your browser, and it’s currency-agnostic — enter figures in SGD or any currency.

ROAS vs ROI — what’s the difference?

ROAS (return on ad spend) is revenue divided by spend, expressed as a multiple — a 5x ROAS means every dollar of spend returned five dollars of revenue. Marketing ROI is the profit relative to spend, expressed as a percentage. ROAS is the quick campaign-health metric; ROI (especially margin-adjusted) tells you whether you actually made money. A campaign can post a healthy ROAS and still lose money if the margin is thin — which is exactly why the break-even ROAS figure matters.

Why break-even ROAS is the number most marketers miss

Break-even ROAS is simply 1 ÷ gross margin. If your gross margin is 50%, you need a 2.0x ROAS just to cover the product cost and the ad spend; at 25% margin you need 4.0x. Any ROAS above break-even is profit; below it, you’re paying to lose money. Knowing your break-even ROAS turns “is 4x good?” from a guess into a decision — and it’s the single most useful figure to set targets and bids against.

Benchmarks and context for Singapore businesses

“Good” ROAS varies enormously by industry, margin and funnel stage — a high-margin SaaS business and a low-margin retailer should chase very different targets. Rather than anchor on a generic benchmark, calculate your own break-even ROAS from your margin, then aim comfortably above it. Also remember that ROAS on paid channels ignores the compounding value of organic SEO and AI-search visibility, which keep returning long after the ad spend stops.

Frequently asked questions

What is a good ROAS?

It depends on your margin. Calculate your break-even ROAS (1 ÷ gross margin) and treat anything comfortably above it as good. A 4x ROAS is excellent at 25% margin (break-even) versus merely fine at 60% margin.

Should I include my product/service costs in ROAS?

Standard ROAS is just revenue ÷ ad spend and ignores product cost. That’s why this tool also shows margin-adjusted gross profit and break-even ROAS — so you see whether the campaign is actually profitable, not just high-revenue.

How is marketing ROI different from ROAS?

ROAS is a revenue multiple (5x); marketing ROI is a profit percentage ((revenue − spend) ÷ spend). ROI is the truer measure of whether the marketing paid off, especially once you factor in margin.

Does this include the value of SEO and organic traffic?

No — this calculates the ROI of a specific spend and its revenue. Organic SEO and AI-search visibility compound over time and aren’t captured in a single ROAS figure, which is one reason they often deliver the best long-run marketing ROI of all.
