These are guide ranges, not rules. Your category, stage, market and timing will move them, so use them to work out where to look, not to mark yourself pass or fail.
| Metric | Benchmark | Notes |
|---|---|---|
| How to calculate MER | Total revenue / total ad spend, across every channel | Measure both over the same period. MER reads higher than any single platform's attributed ROAS, so track your own trend monthly rather than comparing it with platform numbers. |
| MER at $1M-$5M | 1.5-2.5x | Most demand is still paid for at this stage. Healthy MER climbs with scale as brand demand compounds, so read the trend as well as the level. |
| MER at $5M-$10M | 2.5-3.5x | MER counts revenue the ads never bought, such as email, SMS, organic and repeat customers, so it rises as those grow. |
| MER at $10M-$25M | 3.0-4.5x | The soundbite: 3x+ once past about $10M, and 4x+ is strong. |
| MER past $25M | 3.5-6.0x+ | Brand demand is compounding by now, so a growing share of revenue arrives without a click to pay for. |
| Growing vs plateaued brands | ~3.8x for brands growing 30%+ a year, against ~2.1x for plateaued ones | Efficiency and growth move together: the brands compounding brand demand get more revenue from every ad dollar. |
| MER vs ROAS | MER is all revenue over all ad spend; ROAS is one platform's attributed revenue over its spend | Use ROAS to optimise within a channel, then judge the business on blended MER. Every platform claims the same sale, so platform ROAS never adds up. |
| MER vs break-even ROAS | It's not MER's test: break-even ROAS grades acquisition, MER is graded against the stage bands | Break-even ROAS (1 divided by contribution margin) is an acquisition test for campaigns that win new customers. MER blends in revenue the ads never bought, so clearing the bar on MER proves nothing about acquisition. Business-wide, though, an MER below 1 / contribution margin means total ad spend is bigger than the contribution it earns. |
| MER alongside other metrics | No: read it alongside nCAC, new-customer mix and contribution margin | MER is an efficiency ratio, not an attribution model. A 3x MER can be healthy at a 70% gross margin and a loss-maker at 35%. |
| Below $1M | No band below about $1M | Get the first-order economics right first, then let MER climb with scale. |
How to use these benchmarks
These ranges are guides, not guarantees or rules. They are drawn from The DTC Playbook and Rob Ward's experience taking Quad Lock from $0 to a $500M exit, cross-checked against widely cited DTC data. The point is not the exact number - it is whether you sit well above or below it, and what to do about the gap. Your category, stage, market and timing all move them, so judge yourself against your own trend as well.
