Reddit Ads Promoted Post ROAS Calculator: Measure Ad Profitability for 2026

Calculate your Reddit Ads return on ad spend (ROAS) from promoted posts, including clicks, conversions, and profit margin.

Mathematical Audit

How Reddit Ads ROAS Is Calculated

ROAS measures total revenue generated per dollar of ad spend.

Clicks = Ad Spend ÷ CPC
Conversions = Clicks × (Conversion Rate ÷ 100)
Revenue = Conversions × Average Order Value
ROAS = Revenue ÷ Ad Spend

A ROAS of 1.0x means break-even. Most e-commerce advertisers target a minimum 3x–4x ROAS on Reddit.
