New customer ROAS
Revenue from first-time buyers per rupee of ad spend. It separates ads that grow your customer base from ads that mostly sell to people who would have bought from you anyway.
A first-time buyer is someone whose first ever order with the brand is this one.
What is new customer ROAS?
Regular ROAS counts every order an ad is credited with, whether the buyer is brand new or has ordered ten times before. Existing customers are cheap to convert and buy more often, so ads that reach them tend to post flattering numbers.
New customer ROAS keeps only the revenue from people placing their first ever order. It answers the question growth depends on: is this ad bringing in customers you didn't have?
How it's calculated
Start with the same credited orders that make up true ROAS. For each one, check whether the customer has ever ordered before. Keep the first orders, drop the rest.

Worked examples
Example 1: A prospecting campaign quietly turning into retargeting
An illustrative prospecting campaign at ₹1,00,000 a week. Its true ROAS holds steady around 3.0 for a month. Its new customer ROAS doesn't.
| Week | Tracked revenue | New customer revenue | True ROAS | New customer ROAS | New share |
|---|---|---|---|---|---|
| Week 1 | ₹3,00,000 | ₹2,40,000 | 3.00 | 2.40 | 80% |
| Week 2 | ₹3,10,000 | ₹2,17,000 | 3.10 | 2.17 | 70% |
| Week 3 | ₹3,05,000 | ₹1,83,000 | 3.05 | 1.83 | 60% |
| Week 4 | ₹3,00,000 | ₹1,35,000 | 3.00 | 1.35 | 45% |
- On ROASNothing looks wrong. The campaign returns about ₹3 for every rupee, week after week.
- UnderneathIts new customer ROAS almost halves, from 2.40 to 1.35. By week 4, more than half its revenue is from people who already buy from you. It's drifting into retargeting.
Example 2: Two campaigns, same ROAS
Each spends ₹2,00,000 and is credited with ₹6,00,000 of revenue, a true ROAS of 3.00.
Using it to decide
Read new customer ROAS next to true ROAS, and judge it against the first-order value you can afford to pay for. These thresholds on new customer share are starting points for prospecting.
Common mistakes
- Trusting platform "new customer" flagsPlatforms only know who they've seen, not your full order history. Use your store's records.
- Expecting it to match ROASIt's always lower. Judge it against what a first order is worth to you, not against ROAS targets.
- Weak identity matchingMatching on email alone counts guest-checkout regulars as new.
- Ignoring what comes nextA low NC ROAS can still pay off if those buyers repeat. Pair it with LTV.
Frequently asked questions
How is new customer ROAS different from new customer CAC?
New customer CAC tells you what one new buyer costs. New customer ROAS tells you how much first-order revenue each rupee brings in. One is about cost per customer, the other about value per rupee.
Does it include the customer's later orders?
No. It counts only the first order. Later orders belong in LTV, which tells you whether a lower new customer ROAS is still worth paying.
What new customer share should a prospecting campaign have?
As a starting point, above 60% suggests it's genuinely acquiring. Below 40% for a couple of weeks suggests it's mostly reaching existing customers. Tune both to your brand's repeat rate.
