Facebook Ads Cost Calculator
Model your full Facebook Ads funnel — from clicks to qualified leads, sequence completions, sales, gross profit, ROAS, and true net ROI.
How to Use This Calculator
Model your complete Facebook Ads funnel in minutes. Go from ad spend to true net ROI using your real funnel conversion rates and unit economics.
Enter your Facebook Ad Spend and CPC
Pull total monthly ad spend from Meta Ads Manager. Average CPC is shown in the campaign or ad set view. Add agency/management fees separately to get an accurate total cost picture.
Set your funnel conversion rates
Lead Conversion Rate = % of clicks that become inquiries. Qualified Lead % = % of inquiries that pass screening. Sequence Completion Rate = % that finish your nurture flow. Up-Sell Take Rate = % that convert to sale.
Enter your business economics
Avg. Revenue Per Sale is your average transaction value. Product Cost is your direct COGS per unit — the variable cost to deliver one sale. These drive gross profit per sale.
Read your lead and conversion metrics
The calculator shows total sessions, raw inquiries, cost per inquiry, qualified leads, sequence completions, and total monthly sales — your full funnel at a glance.
Analyse your business metrics
Gross Revenue, CPA, Gross Profit per Sale, Gross Profit per Month, ROAS, and true Net ROI are all derived automatically from your inputs — no spreadsheet needed.
Use ROAS and Net ROI to make decisions
ROAS > 6× = scale aggressively. 2.5–6× = healthy, optimise funnel. 1–2.5× = marginal, improve conversion rates. Below 1× = loss-making, pause and diagnose before increasing spend.
