The Five Numbers Every Home Improvement Contractor Should Know Before Spending Another Dollar on Leads

Most home improvement contractors make monthly marketing decisions with one number: cost-per-lead. That number is not enough. It never was.

There are five metrics that actually determine whether your marketing spend is working. If you do not know all five, you are making budget decisions with incomplete information. Here is what they are, how to calculate them, and why each one changes how you think about your lead sources.

1. Set Rate by Source

Set rate is the percentage of leads from a given source that convert into scheduled appointments.

To calculate it: divide the number of appointments set from a source by the total number of leads received from that source, then multiply by 100.

A lead platform delivering 100 leads per month with a 25% set rate is producing 25 appointments. The same spend on a source with a 55% set rate produces 55 appointments. That difference compounds through every stage of the funnel.

Most contractors know their overall set rate. Very few know it broken down by source. The overall number is almost meaningless for budget decisions. The source-level number tells you everything.

2. Demo Completion Rate by Source

Demo completion rate is the percentage of scheduled appointments that actually occur. A set appointment that does not show up costs you the same in sales time and overhead as one that does, with zero revenue potential.

To calculate it: divide completed demonstrations by scheduled appointments from a given source, then multiply by 100.

Cancellations and no-shows are not distributed evenly across lead sources. Some sources produce leads that set easily but cancel frequently. Others produce leads that are harder to set but show up consistently. If you are only tracking set rate, you are missing half the picture.

Contractors who track this number typically discover one or two sources with significantly higher no-show rates than the rest. Cutting or reducing spend on those sources often improves sales team efficiency more than any other single action.

3. Close Rate by Source

Close rate is the percentage of completed demonstrations that result in a signed contract.

To calculate it: divide closed jobs by completed demonstrations from a given source, then multiply by 100.

This is the metric that most directly reflects lead quality. A high-volume, low-cost source that closes at 8 percent is producing fundamentally different economics than a lower-volume, higher-cost source that closes at 30 percent. No CPL comparison between those two sources is meaningful without knowing the close rate.

Close rate is also the metric most influenced by lead intent. Leads generated through bottom-of-funnel intent signals, specific search queries, or direct referrals close at higher rates than leads generated through broad awareness campaigns or shared platforms. The cost difference between those sources rarely reflects the close rate difference.

4. Cancellation Rate by Source

Cancellation rate is the percentage of signed contracts that cancel before installation is complete.

To calculate it: divide cancelled jobs by total signed jobs from a given source, then multiply by 100.

This is the metric most contractors track too late. A cancellation after a contract is signed but before installation represents a full absorption of marketing cost, sales cost, and administrative cost with zero revenue offset. In high-cancellation environments, this single number can render a lead source unprofitable even when the close rate looks acceptable.

5. Cost-Per-Acquired-Revenue by Source

This is the metric that combines all four previous numbers into a single comparable figure. It tells you how much it costs to produce one dollar of revenue from each lead source.

To calculate it: take total spend on a source for a given period and divide it by the total revenue generated from jobs that originated from that source in the same period.

A source producing a $0.08 cost-per-acquired-revenue is generating $12.50 in revenue for every dollar spent. A source producing a $1.40 cost-per-acquired-revenue is generating $0.71 in revenue for every dollar spent. Those are not comparable sources and they should not receive comparable budget allocations.

This number requires connecting your lead source data to your closed job data, which most contractors have never done in a systematic way. But it is the only number that gives you a true apples-to-apples comparison across every source in your marketing mix.

How to Get These Numbers

The challenge with all five of these metrics is that they require data from multiple systems that do not naturally communicate with each other. Your lead platform knows how many leads it sent you. Your CRM knows how many appointments were set and what the outcome was. Your job management system knows what closed, what cancelled, and what the final job value was.

Connecting those three data sets, standardizing them, and running the right calculations against your specific business economics is the analysis most contractors have never had access to.

It is not because the analysis is impossible. It is because no one in the standard vendor ecosystem has any incentive to build it for you. Your lead vendor benefits when you do not know your close rate by source. Your agency benefits when you cannot see cancellation rates. The status quo of incomplete data serves everyone except you.

These five numbers exist in your business right now. The revenue intelligence to surface them clearly is what has been missing.
