Plumbing Customer Acquisition Cost Calculator
Work out what winning one customer costs and whether the first job covers it.
Result
Sales time is included because it is a real cost of winning work even though it never appears on an advertising invoice. Recovering under 100% on the first job is normal in the trades, provided customers come back.

- All acquisition spend, including the quoting time usually left out.
- Close rate, since unconverted leads are paid for too.
- Whether the first job covers the cost or the relationship has to.
Where this one goes wrong
Counting advertising only. Time spent quoting, travelling to quote and following up is a real acquisition cost, and omitting it makes every channel look cheaper than it is.
Questions
About this calculator
What should acquisition cost include?
Advertising and directory fees plus the sales and admin time spent converting. The second is frequently the larger and is almost never counted.
Should the first job cover it?
Ideally, because it removes the risk. Where it does not, the business is betting on retention and that bet needs measured evidence behind it.
How does it compare to lifetime value?
The ratio between them is the number that matters. A narrow ratio means you are buying customers you barely profit from.
The formula
acquisition cost = (marketing + sales cost) / customers won

| Marketing spend per month | $3,200 |
| Sales time and tools | $900 |

| Cost per lead | $58.57 |
| Customers per month | 22 |
| Gross profit on the first job | $240 |

How sensitive the answer is
Holding everything else steady and changing only marketing spend per month, this is what happens to cost to win one customer. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Marketing spend per month ($) | Cost to win one customer |
|---|---|
| $1,600 | $111.61 |
| $2,400 | $147.32 |
| $3,200 example above | $183.04 |
| $4,800 | $254.46 |
| $6,400 | $325.89 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.

Before you rely on this number
Pipe sizing, flow and pressure figures depend on the actual fittings, the run, the material and local code. Code requirements vary by jurisdiction and override any general calculation, so check what applies where the work is happening.
Estimating is the easy part
The jobs you never hear about cost more than the ones you mis-measure. BDEVY builds the marketing, systems and automation that bring them in.
