  • Break-even: projects needed to cover annual marketing cost, converted to months at the estimated project rate
  • ROI: (annual project profit contribution − annual marketing cost) ÷ annual marketing cost
  • Cost per lead: monthly spend ÷ leads per month
  • Assumes consistent lead flow over 12 months

Construction Marketing ROI Calculator: FAQs

What does the Construction Marketing ROI Calculator measure?

The calculator estimates marketing return using the project revenue, profit margin, monthly spend, lead volume and conversion rate you enter. Project revenue is not profit: the entered margin converts it into an estimated project profit contribution, and annual marketing cost is then subtracted. This is not accounting net profit, cash flow or a forecast, and it does not use an assumed industry return.

How do I estimate projects per year for the calculator?

Use a lead volume and conversion rate that your delivery capacity can support. If you lack reliable historical data, start with a conservative scenario and compare it with a stronger scenario rather than treating the default inputs as forecasts.

What is a realistic cost-per-lead for construction marketing?

There is no reliable universal figure. Cost per lead varies by trade, geography, channel, competition, qualification standard and contract value. Use your actual channel spend divided by genuinely qualified enquiries, then compare that cost with your close rate and profit per project.

What is a typical ROI for construction marketing?

There is no single typical ROI for construction marketing. The result depends on contract value, margin, lead quality, win rate, sales cycle and repeat work. Use the calculator to test your own assumptions and compare the output with closed-won revenue.

How long does it take to break even on construction marketing?

Break-even depends on the sales cycle and when won work produces cash and profit. SEO, content and relationship-led activity usually build over time. Treat the calculated period as a simplified scenario based on your inputs, not a promised timescale.

What does profit per project mean in the calculator?

Use the profit left after direct costs and the overhead allocation you apply internally. Margins vary substantially by contractor and package, so replace the default input with a conservative figure from your own management accounts.

Is the ROI calculator specific to UK construction?

Yes. Its inputs use construction project value, margin, lead volume and conversion rate. The default values are examples for demonstrating the calculation, not UK construction benchmarks.

How should I use the calculator results when setting a marketing budget?

Use conservative inputs to identify the maximum acquisition cost your expected project profit can support. Then compare the result with the practical budgeting method in our construction marketing budget guide before committing spend.
