The number that decides it
- Break-even ROAS
- 2.22x
- Target ROAS (50% margin of safety)
- 3.33x
- Most you can pay per customer
- ₹1,500
At a 45% margin you need 2.22x just to stand still. Any agency quoting a ROAS target without asking your margin is quoting a number that cannot mean anything.
Projected — profitable

Assumptions behind this+
- — Reels typically run 25–40% below feed CPM. Tier-2/3 geos cut CPM 30–50%.
- — Meta CPC range used: ₹2–₹25, India.
- — Revenue counts first purchase only — repeat orders make the real picture better.
- — Platform-reported ROAS usually flatters this by counting returning customers and view-through conversions.
- — Below roughly ₹1.5–2L a month on one channel, results are mostly noise rather than signal.
- — Management fees, creative production and GST sit outside this number.
How to read it
Figures are computed in INR and converted at indicative rates, August 2026. Good for comparison, not for invoicing.
- 01
Break-even ROAS is 1 ÷ gross margin. At 40% margin you need 2.5x just to stand still.
- 02
Landing page conversion rate is usually the cheapest lever on this page, and the one nobody touches.
- 03
Platform-reported ROAS runs higher than this because it counts returning customers and view-through conversions.
