Google Ads Cost Per Lead Calculator
Your cost per lead is simply ad spend ÷ leads — or, from the click side, cost-per-click ÷ conversion rate. Enter your three numbers below to see how many leads your spend should produce and what each one will cost.
Estimates only — your real cost per lead depends on industry, location, competition and how well your landing page converts. Use this as a baseline, then refine with live data.
How this calculator works
Cost per lead (CPL) is the single clearest measure of whether your ads are turning money into enquiries. The math runs in two short steps:
- Clicks = ad spend ÷ average cost-per-click.
- Leads = clicks × conversion rate.
- Cost per lead = ad spend ÷ leads (which is the same as cost-per-click ÷ conversion rate).
Worked example: $1,500 spend at a $3 cost-per-click buys 500 clicks. At a 7% conversion rate, that's 35 leads — a cost per lead of about $43.
What's a good cost per lead?
There's no universal "good" number — it depends entirely on what a lead is worth to you. The honest benchmark is simple: your cost per lead should sit comfortably below the value of a lead.
Lead value = average customer value × close rate. If a customer is worth $600 and you close 1 in 4 leads, each lead is worth ~$150 — so a $43 cost per lead leaves a healthy margin. For more on this, see what counts as a good cost per lead.As a rough orientation only, typical local cost-per-lead ranges look like this:
Type of business Typical cost per lead Lower-competition local services $20–$60 Home services / trades $40–$120 High-value (legal, medical, B2B) $100–$400+ How to lower your cost per lead
- Raise your conversion rate — the fastest lever. Going from 5% to 10% halves your cost per lead. A focused landing page is usually the biggest win.
- Cut wasted spend — negative keywords, tighter match types and trimming poor locations/devices all remove clicks that never convert.
- Improve Quality Score — better ad relevance and landing-page experience lower your cost-per-click over time.
If your cost per lead looks high, it's almost always fixable. Get in touch and I'll tell you honestly where it's coming from.
Frequently asked questions
How do I calculate cost per lead?Divide your ad spend by the leads it produces. From the click side: cost per lead = cost-per-click ÷ conversion rate. A $3 CPC at a 7% conversion rate is about $43 per lead.
What is a good cost per lead?One that's comfortably below the value of a lead (customer value × close rate). Judge CPL against that, not a generic benchmark.
How can I lower my cost per lead?Raise your conversion rate (usually the landing page), cut wasted spend with negatives and tighter targeting, and improve Quality Score to bring CPC down.
What's a good conversion rate?For local-service pages, 5–10% click-to-lead is healthy. Below ~3% usually points to a weak page or poorly matched keywords.
Paying too much per lead?
I'll find where your cost per lead is inflated — wasted clicks, a leaky landing page, or the wrong keywords — and show you how to bring it down. No pitch, no obligation.
