ROAS & LTV Calculator
ROAS Reality Check
Drag your real numbers in. See day-one ROAS and whether your customers are worth acquiring once you factor in AOV and lifetime value — not just whether the first order "worked."
Illustrative tool — the numbers above are a sample. Plug in your own to see where you land.
How this is calculated
Day-one ROAS is revenue divided by spend — the number most dashboards lead with. This tool goes a step further: it calculates your break-even ROAS from gross margin (1 ÷ margin), then layers in customer lifetime value to show LTV:CAC — what a customer is actually worth once repeat purchases are factored in, not just their first order.
What counts as a "good" ROAS?
There isn't one number — it depends entirely on your gross margin. A 3× ROAS is losing money at a 20% margin but comfortably profitable at 40%. Your break-even ROAS (1 ÷ margin) is the real floor, not some industry-wide benchmark.
Why would I keep spending if day-one ROAS misses my target?
If LTV:CAC is strong — meaning customers come back and spend again — a weak first-order ROAS can still be a great investment. The real lever in that case is repeat purchase rate, not squeezing more out of the first click.
How is break-even ROAS calculated?
It is 1 divided by your gross margin. At a 42% margin, you need 2.38× just to cover the cost of the sale — anything above that is contributing profit, anything below it is losing money on that order.
What's the difference between ROAS and LTV:CAC?
ROAS looks at one transaction: revenue over spend. LTV:CAC compares what a customer is worth across their full relationship with you against what it cost to acquire them — a much better read on whether a channel is actually working.
