  • Enter spend, leads, and jobs won

    Add what you spent on a channel or campaign, the leads it produced, the jobs you won, and your average job value. The calculator returns cost per lead, cost per acquisition (CAC), and lead-to-job conversion rate.

  • See ROAS and true profit ROI

    Your gross margin turns revenue ROI into profit ROI (ROMI): revenue ÷ spend gives ROAS, while (gross profit − spend) ÷ spend shows the profit each marketing dollar actually earns, with a break-even ROAS line so you know when a channel is losing money.

  • Check lifetime value against acquisition cost

    Add repeat jobs per customer to see customer lifetime value and your LTV:CAC ratio, the 3:1 rule of thumb, then compare every metric to typical home-service benchmarks before you scale or cut spend.

How plumbing contractors measure marketing ROI

Revenue is not proof a channel works. A campaign can post a 3× return on ad spend and still lose money once cost of delivery is subtracted, or win on the first job but only pay off across a customer's lifetime. Marketing ROI analysis separates the two by running spend, leads, and won jobs through the standard metrics, cost per lead, cost per acquisition, conversion rate, ROAS, and gross-profit ROI, so you can compare Google Ads, Local Service Ads, mailers, and referrals on the same footing.

This calculator uses the industry-standard definitions: ROAS is revenue ÷ ad spend, CAC is spend ÷ customers acquired, and profit ROI (ROMI) is (revenue × gross margin − spend) ÷ spend. It also derives your break-even ROAS (1 ÷ gross margin), the point where a channel stops covering its own cost, and an LTV:CAC ratio against the 3:1 benchmark. Pair it with the Profit Margin and Break-Even calculators so the leads you buy clear both your job margin and your overhead.

Marketing ROI Calculator FAQs

Track the spend on one channel and the jobs it won over the same period. Revenue = jobs won × average job value. For true profit ROI, multiply revenue by your gross margin to get gross profit, then use (gross profit − spend) ÷ spend × 100. Example: $5,000 spend produces $15,000 revenue at 40% margin = $6,000 gross profit, so ROI = ($6,000 − $5,000) ÷ $5,000 = 20%.
ROAS (return on ad spend) is revenue ÷ ad spend, a $15,000/$5,000 campaign is 3× ROAS. It ignores what it costs to deliver the work. Marketing ROI applies your gross margin first, so it reflects the actual profit each marketing dollar earns. A channel can look great on ROAS and still lose money on profit ROI if your margins are thin.
A healthy marketing ROAS is generally 4× or higher, and home-service Local Service Ads often run 6-9×. Cost per lead varies by trade and channel, roughly $40-$165, and cost per booked job (CAC) commonly lands $130-$400. Your break-even ROAS is 1 ÷ your gross margin: at 50% margin you need at least a 2× ROAS just to cover the cost of the work.
