On 2026 benchmarks, consulting / professional services leads run $60 to $190, with a median around $110 and a typical lead-to-customer close rate near 20%. What your business can afford is a separate number: gross profit per customer, times your close rate, divided by a profit factor. The calculator below runs that math with consulting / professional services defaults loaded.
You can pay up to $240 per lead at your target profitability, and even expensive consulting / professional services leads run about $190. That $50 of headroom is what funds testing: it buys the imperfect first month every new lead source has, without putting the account underwater.
Two readings from the same dataset: the band above is the blended cost-per-lead row; paid search alone implies $65 / $107 / $258 per lead (Google cost per click divided by landing-page conversion at each quantile). Search-only leads usually cost more than the blend.
| Gross profit per customer | $3,600 |
| Value per leadusing the 20% industry benchmark close rate | $720 |
| Breakeven lead cost | $720 |
| Your ceiling | $240 |
Balanced: a lead may cost up to a third of the money it brings in. A sensible default for most businesses.

Consulting leads carry the longest consideration cycles in this dataset, and the math has to respect that. Engagements run from $5,000 project work to six-figure retainers, buyers compare providers over weeks, and a lead that closes in month three is normal. The band prices reflect a market where the payoff justifies patience: professional-services leads sell at premium prices because a single engagement repays a quarter of spend.
Close rates here depend on qualification more than persuasion. The band runs 10 to 30 percent, and the difference between those numbers is usually a scoping call that disqualifies bad-fit inquiries early. Firms that put a partner on first calls close at the top of the band; firms that route leads to a contact form and wait sit at the bottom. The calculator's close input should reflect qualified-opportunity close, with the qualification screen counted as part of lead cost.
Authority assets change this vertical's economics in a way no other input does. A firm with published work, a known specialty, and referenceable clients converts the same lead at multiples of a generalist's rate, because the buyer arrives partly sold. In lead-math terms, the specialty is a close-rate multiplier that compounds every dollar of lead spend after it.
A worked example: a firm averaging $18,000 engagements at 60% margin keeps $10,800 per client. Closing 15% of qualified inquiries makes a lead worth $1,620; the divide-by-three ceiling of $540 clears the market's expensive end nearly three times over. Even at an 8% close, the ceiling ($288) stays above the top of the band, so consulting rewards patience with lead sources that other verticals would cut at week six.
The pipeline caveat: consulting revenue is lumpy, and the temptation is to buy leads only when the pipeline empties. Lead prices do not care about your utilization, and starting from zero every few months means paying ramp-up costs repeatedly. A small, permanent lead budget outperforms a large intermittent one in almost every professional-services model.
A full sales cycle, which for most engagement sizes means 90 days minimum. Consulting leads routinely close in month two or three; judging a source on 30-day results discards the exact leads the category is built on.
Ten to 30 percent of qualified opportunities, with the spread explained by who takes the first call and how early bad fits get screened out. A partner-led first call with a scoping screen reliably sits at the top of that range.
