Marketing ROI & Customer Acquisition Cost Calculator

Turn door-hanger or flyer campaign mechanics into cost per new customer (CAC), campaign ROI, LTV:CAC, and a profitability verdict — with recurring lifetime-value modeling.

Campaign reach & cost

Pieces distributed

Door hangers, flyers, or mailers dropped.

Printing & design

Distribution / labor

Other cost

Research, permits, list. Set 0 to omit.

Conversion

Response rate

Typical door-hanger response is about 2% (range 0.5%–5%). This is a guess — adjust to your market.

Close rate

Of the people who respond, how many actually buy. 40% is a common starting point.

Job economics

Net profit per job

Net profit per job — what's left after costs, NOT the price you charge. Using revenue here inflates ROI.

Recurring service (model lifetime value)

Jobs per customer

How many jobs a recurring customer buys (e.g. mows in a season). A rough lifetime estimate — churn isn't modeled, so keep it conservative.

Cost per new customer (CAC)

—

Export

CAC = total cost ÷ new customers; ROI = (value − cost) ÷ cost; LTV:CAC ≥ 3:1 is healthy How?

How this is calculated

The calculator works forward from your campaign mechanics to the headline metrics, instead of asking you for the answers it should be computing.

leads             = pieces × responseRate
new customers     = leads × closeRate
value per customer = profitPerJob × jobsPerCustomer   (×1 if not recurring)
total value       = newCustomers × valuePerCustomer
total cost        = printing/design + distribution + other
CAC               = totalCost ÷ newCustomers
ROI %             = (totalValue − totalCost) ÷ totalCost × 100
LTV:CAC           = valuePerCustomer ÷ CAC
break-even response = (totalCost ÷ valuePerCustomer) ÷ (pieces × closeRate)

CAC is cost ÷ customers (the canonical definition). A healthy LTV:CAC is 3:1 or better — that floor drives the verdict and the "Healthy" badge. The verdict is Profitable when ROI is positive and LTV:CAC ≥ 3, Marginal when ROI is positive but the ratio is thin, and Underwater when the campaign lost money.

The recurring multiplier is the point. A $25 single mow can look marginal at a $44 CAC; the same customer over a 20-visit season is worth $500, which flips the verdict to Profitable. Churn is not modeled, so keep jobs-per-customer conservative.

The benchmark line cites Focus Digital's lawn-care channel figures (door hangers average ~$86 CAC). It is advisory context, not a verdict.

Formula: CAC = total cost ÷ new customers; ROI = (value − cost) ÷ cost; LTV:CAC ≥ 3:1 is healthy
