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.

STEP 01

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.

STEP 02

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.

STEP 03

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.

STEP 04

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.

STEP 05

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.

STEP 06

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.
