PPC Budget Calculator
Calculate your pay-per-click advertising budget based on target clicks and estimated cost per click.
Plan daily and monthly ad spend.
Pay-Per-Click (PPC) budget planning determines how much you need to spend on paid search or social ads to hit a target number of leads or sales.
The core formulas:
Required Budget = Target Clicks × Cost Per Click (CPC)
Target Clicks = Target Conversions / Conversion Rate
Cost Per Acquisition (CPA) = Budget / Conversions
Return on Ad Spend (ROAS) = Revenue / Ad Spend
What each variable means:
- Target Conversions — the number of leads, sales, or sign-ups you want each month
- Conversion Rate — percentage of clicks that become conversions (industry average: 2–5%)
- CPC — average cost per click in your niche (varies from $0.50 for broad topics to $50+ for legal/finance)
- CPA — how much you pay per conversion; must be lower than your profit per sale
Worked example: You want 100 sales per month. Your landing page converts at 4%. Your average CPC is $1.80.
Target clicks = 100 / 0.04 = 2,500 clicks Required budget = 2,500 × $1.80 = $4,500/month CPA = $4,500 / 100 = $45 per sale
If your product sells for $120 with a $60 margin, your CPA of $45 leaves a $15 profit per sale.
Typical CPC ranges by industry:
- E-commerce: $0.50–$2.00
- Software/SaaS: $3.00–$10.00
- Legal services: $15–$50+
- Finance/insurance: $10–$30
Always set a daily budget cap to avoid runaway spend, and monitor Quality Score to lower CPC over time.
