Free tool · Runs entirely in your browser
Ad spend calculator
See what your monthly ad spend really costs over 3 years, and what that same traffic could be worth for free if it came from organic search instead.
Uses illustrative industry-average benchmarks, not live ad-auction data — a ballpark to prompt a real look at your numbers, not a quote.
What Is This Ad Spend Calculator?
This calculator shows what your current monthly ad spend really costs over 3 years, and what that same volume of traffic could be worth for free if it came from organic search instead.
Enter your monthly ad spend and select your industry, and it applies illustrative industry-average benchmarks for cost per click, cost per lead, and an organic-equivalent multiplier, not live ad-auction data.
What This Ad Spend Calculator Helps You Calculate
- Estimated clicks per month: Your monthly spend divided by the industry's benchmark cost per click.
- 3-year ad cost: Year 1 at your current spend, Year 2 at +15%, and Year 3 at +32%, reflecting typical rising acquisition costs.
- Equivalent organic clicks: The traffic volume organic search would need to deliver to match your paid clicks, using the industry's organic multiplier.
- Organic value: What that equivalent organic traffic would be worth monthly, annually, and over 3 years, priced at the same industry CPC.
- Cost per lead: The industry benchmark cost per lead, shown alongside your spend.
What This Ad Spend Calculator Does Not Do
- Does not work backward from a clicks, leads, or conversions target; it works from your current monthly spend and industry
- Uses illustrative industry-average benchmarks, not live ad-auction data, a ballpark to prompt a real look at your numbers, not a quote
- Does not predict actual advertising costs or guarantee clicks, leads, conversions, or revenue
- Does not guarantee that organic search will actually reach the equivalent traffic shown
- Does not automatically manage campaigns or connect to advertising platforms
- The 15% and 32% year-over-year cost increases are illustrative assumptions, not a forecast for your account
Why Use an Ad Spend Calculator?
A campaign budget should be connected to what you are trying to achieve. Instead of choosing an advertising budget without context, you can use available campaign metrics to estimate the spend associated with a specific goal.
- See what your ad spend actually adds up to over 3 years, not just this month
- Understand the traffic value organic search would need to replace to match it
- See how rising acquisition costs compound year over year
- Compare paid and organic acquisition using the same industry benchmarks
- Use the comparison as a starting point for the ads-versus-SEO conversation

Frequently Asked Questions
What is this Ad Spend Calculator actually calculating?
It projects your current monthly ad spend forward 3 years, with typical cost increases in years 2 and 3, and compares that to what the equivalent traffic would be worth if it came from organic search instead.
Do I need to know my own CPC or cost per lead?
No. Select your industry and the tool applies illustrative benchmark figures for CPC, cost per lead, and organic-equivalent traffic. You only need to enter your monthly spend.
Where do the benchmark numbers come from?
They're illustrative industry averages built into the tool, not live ad-auction data. They're meant as a ballpark to prompt a real look at your own numbers, not a quote.
Why do Year 2 and Year 3 cost more in the calculation?
The calculator applies a +15% increase in Year 2 and a +32% increase in Year 3 over Year 1, reflecting the common pattern of rising customer acquisition costs. These are illustrative assumptions, not a forecast for your specific account.
Can I use this to plan a target number of leads or conversions?
Not directly. This calculator starts from your monthly spend and industry, not from a leads or conversions target.
How much should I spend on advertising?
There is no single budget that works for every business. Your budget can depend on your target customers, campaign objective, expected acquisition cost, available resources, and historical performance.
