Cost Per Lead (CPL) = marketing spend divided by leads generated. Most businesses should aim for CPL of 5-20% of expected customer value. This calculator shows CPL plus downstream revenue and ROI.
10,000 spend, 500 leads = 20 CPL. At 15% lead-to-customer conversion (75 customers) × 500 average value = 37,500 revenue. ROI 275%. Strong metrics for most B2C and B2B marketing.
Use for channel comparison. Facebook leads at 15 CPL but 5% conversion vs Google leads at 40 CPL but 25% conversion - Google wins despite higher CPL. Look at full funnel economics, not CPL alone.
Quick example
With marketing spend of 10,000 and leads generated of 500 (plus lead-to-customer rate of 15% and average customer value of 500), the result is 20.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Marketing Spend, Leads Generated, Lead-to-Customer Rate, and Average Customer Value. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
CPL = spend / leads. Revenue = leads × conversion × customer value. ROI = (revenue - spend) / spend. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
What to do with a low result
A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
