Quick answer
A PPC budget calculator multiplies target clicks by average CPC. 1,500 clicks at $2.40 needs a $3,600 monthly budget, about $118 a day using the 30.4 days Google Ads uses for a month. Expected leads = clicks × conversion rate, so a 4% rate gives 60 leads at $60 each.
What is a PPC budget calculator?
A PPC budget calculator is a tool that turns traffic goals into an ad budget. Monthly budget = target clicks × average CPC, daily budget = monthly budget ÷ 30.4, leads = clicks × conversion rate and cost per lead = budget ÷ leads.
How do you use the PPC Budget Calculator?
- Enter how many clicks you want each month.
- Enter an average CPC from Keyword Planner or your past campaigns.
- Enter your expected conversion rate from click to lead or sale.
- Optionally add the value of one lead to see return on ad spend.
- Read the monthly budget, daily budget, leads and cost per lead.
How do I calculate a PPC budget?
Monthly PPC budget = target clicks × average CPC, so 1,000 clicks at $2 needs $2,000. Divide by 30.4 for the daily budget, because Google Ads caps monthly spend at 30.4 times the average daily budget for most campaigns, as its daily budget guide explains.
How do I work out budget from a lead goal?
Divide the lead goal by your conversion rate to get clicks, then multiply by CPC: 50 leads at a 5% rate needs 1,000 clicks, and at a $3 CPC that is $3,000 a month. Use the target leads field to calculate this automatically.
Why might Google Ads spend more than my daily budget?
Google Ads can spend more than the average daily budget on busy days, but over a month you are not charged more than 30.4 times the average daily budget for most campaigns. Plan with the monthly total, not one day.
Quick reference
| Target clicks | Avg CPC | Monthly budget |
|---|---|---|
| 500 | $1.20 | $600 |
| 1,000 | $2.00 | $2,000 |
| 1,500 | $2.40 | $3,600 |
| 3,000 | $3.50 | $10,500 |
| 5,000 | $1.80 | $9,000 |
Worked example
Example
Example: a law firm wants 1,500 clicks a month at an average CPC of $2.40. Budget = 1,500 × 2.40 = $3,600 a month, or 3,600 ÷ 30.4 = $118.42 a day. At a 4% conversion rate that is 60 leads, a cost per lead of $60, and if each lead is worth $150, $9,000 in lead value (250% ROAS).
Frequently asked questions
What is a PPC budget?
A PPC budget is the amount you plan to spend on pay per click advertising in a period, usually a month. Platforms such as Google Ads use an average daily budget, so you set the monthly plan and divide it by 30.4.
Where do I find average CPC for my keywords?
Use Google Keyword Planner for estimated top of page bid ranges, or your own Google Ads reports for actual average CPC. Use figures for the same country, language and match types you plan to target.
What conversion rate should I use?
Use your own landing page conversion rate from past campaigns if you have it. If not, start with a cautious estimate, run a small test budget for a few weeks, then update the calculator with the real rate.
How much should a small business spend on PPC?
Start with enough budget to get meaningful data, often a few hundred clicks a month on your main keywords. Then scale spend on campaigns where cost per lead is below what a lead is worth to you.
What is cost per lead?
Cost per lead is ad spend divided by the number of leads. If $3,600 brings 60 leads, cost per lead is $60. Compare it with how much a lead is worth after your close rate to judge profitability.
Should I split budget between SEO and PPC?
Many businesses use PPC for quick, controllable traffic while SEO builds long term organic visibility. PPC data on converting keywords can also guide which topics to target with SEO, so the two often work well together.
