Budget calculator Meta Ads 2026
Enter your AOV, target ROAS and conversion volume. See an indicative budget scenario based on your selected assumptions, not a forecast or a performance guarantee.
Estimate for the chosen conversion cost and volume. Check the account's learning status and business results separately.
How the maths works
Meta's algorithm enters the "Learning Phase" for each new ad set. During this phase, it distributes ads across broad audiences to identify who converts. The interface may show learning statuses when volume is insufficient for the selected optimisation. Event counts, windows and effects vary by objective, account and changes made, so we do not treat a threshold as a universal rule.
Calculator formula
- Target CPA = AOV / Target ROAS (for ecommerce). Example: AOV of RON 250 with ROAS of 3 → target CPA of RON 83.
- Estimated daily budget = Target CPA × Conversions/week / 7 × Number of ad sets. For 50 conversions/week and a CPA of RON 83: 83 × 50 / 7 ≈ RON 593/day in this scenario.
- Monthly budget = Daily budget × 30.
What the calculator does not measure
The calculator shows the mathematical relationship between your inputs. It cannot predict actual ROAS. Results depend on the offer, margin, creative, audience, tracking, season and the business's ability to turn demand into sales.
Want us to check whether your assumptions are realistic?
We review the account or plan, product economics and available data. We identify what needs validating before turning the scenario into an actual budget.
