Use contribution adjusted CAC payback to test customer acquisition economics after onboarding, servicing, payment timing, and retention, then see when cumulative customer cash contribution recovers the acquisition commitment under the entered assumptions.
About this interactive
This interactive tests when customer cash contribution recovers acquisition cost after onboarding, servicing, collection timing, gross margin, and retention are considered together. It supports customer-economics decisions within our FP&A for Startups practice.
Interactive view
The curve follows expected cash contribution after acquisition cost, onboarding, servicing, collection timing, and retention.
What the interactive shows
CONTRIBUTION-ADJUSTED CAC PAYBACK ANALYZER — ILLUSTRATIVE RECORD City Shift Finance CURRENT INPUTS Customer acquisition cost: $9,000 Monthly customer revenue: $2,500 Gross margin: 78% Onboarding cost: $1,800 Servicing cost: $220 / month Payment timing: Monthly, one month lag Retention: 98% Contribution margin target: 65% SUMMARY Contribution payback: 8 months Initial commitment: $10,800 12-month contribution: $17,061 12-month contribution margin: 68.5% Contribution margin target: 65% FINDING After acquisition and onboarding, expected customer cash contribution recovers the initial $10,800 commitment in month 8 under the entered gross margin, servicing cost, retention, and payment timing. The 12-month contribution margin meets or exceeds the entered 65% target, while payment timing and recurring servicing cost determine the cash recovery path. METHOD STATUS The analysis begins with acquisition cost plus onboarding cost as the initial customer commitment. Monthly expected collections are adjusted for the entered payment timing and retention. Gross contribution equals expected collections multiplied by gross margin, less expected servicing cost for the retained customer. Cumulative contribution is tracked for 36 months to identify when the initial commitment is recovered. Planning analysis only.
