Cost per qualified lead calculator

This free cost per qualified lead calculator turns five numbers into the ones that decide a budget: CPL, CPQL, the value of a lead (your break-even cost per lead) and monthly ROI. Everything runs in your browser; nothing you type leaves the page.

Cost per qualified lead (CPQL) calculator

Enter five numbers. CPQL = ad spend divided by qualified leads. Lead value tells you the most a lead may cost.

Monthly ad spend

€

one channel or the total Leads per month

forms, calls, emails Qualified share

enquiries worth pursuing Close rate

qualified leads that become deals Average deal value

€

revenue per won deal

CPQL 62,50 € cost per qualified lead

CPL 25 € cost per raw lead

Lead value (break-even CPL) 180 € qualified × close rate × deal value

Monthly ROI +12.400 € expected revenue minus spend

Profitable

Qualified share and close rate start as estimates. Once you grade leads (qualified, won, lost) and enter deal values, measured numbers replace the assumptions.

How the CPQL calculator works

Four formulas run behind the fields, in this order:

CPL = ad spend / all leads. The price of an inquiry, any inquiry.
CPQL = ad spend / qualified leads. The price of a prospect worth pursuing.
Lead value = qualified share × close rate × average deal value. The most a lead may cost at break-even.
Monthly ROI = expected revenue (qualified leads × close rate × deal value) minus ad spend.

The verdict compares your CPL against your lead value. A CPL well below lead value earns on every inquiry; a CPL above it means the channel needs better qualification or cheaper leads. The full reasoning, with worked examples and the channel-ranking flip between CPL and CPQL, is in our cost per qualified lead guide.

From this estimate to measured numbers

Qualified share and close rate start as guesses. Enalitica runs the same math live on your real channels: every form, call and email is captured with the campaign that sent it, leads get graded with one click, and the per-channel table shows CPQL, value and ROI marked as estimate or actual.

Frequently Asked Questions

What numbers do I need to use the CPQL calculator?

Five numbers: monthly ad spend, leads received, the share of leads that are qualified, the share of qualified leads you close, and your average deal value. The first two come from your ad account and inbox; the other three can start as estimates and be replaced by graded outcomes later.

How does the calculator compute the break-even cost per lead?

Lead value = qualified share × close rate × average deal value. With 40% qualified, a 25% close rate and an 1,800 € deal, one incoming lead is worth 180 €, which is also the most a lead may cost you at break-even. The calculator compares your actual CPL against this number for the verdict.

Does the CPQL calculator store my numbers?

No. Every calculation runs in your browser; nothing you type is sent to a server, stored, or shared. Refreshing the page resets the inputs to the example values.
