The Google Ads Calculator projects what a budget buys: clicks from your CPC, conversions from your conversion rate, and what each conversion costs.
Why does Google Ads matter?
With revenue and margin it tells you whether advertising is actually profitable.
How is Google Ads calculated?
Budget ÷ CPC gives expected clicks; clicks × conversion rate gives conversions; budget ÷ conversions gives CPA — the number to compare against what a customer is worth. Formula: clicks = budget ÷ CPC; conversions = clicks × CVR; CPA = budget ÷ conversions.
What is a good google ads?
~$0.5-$2 (varies hugely by industry)
What are common google ads mistakes?
Using aspirational conversion rates — 2-5% is typical for cold search traffic; landing page quality dominates.

What is the Google Ads Calculator?

The Google Ads Calculator projects what a budget buys: clicks from your CPC, conversions from your conversion rate, and what each conversion costs.

How the Google Ads Calculator works

Budget ÷ CPC gives expected clicks; clicks × conversion rate gives conversions; budget ÷ conversions gives CPA — the number to compare against what a customer is worth.

clicks = budget ÷ CPC; conversions = clicks × CVR; CPA = budget ÷ conversions
  1. Enter your budget for the period.
  2. Enter average CPC (from keyword planner or campaign history).
  3. Enter your conversion rate — sitewide averages hide big differences; use the landing page's rate.
  4. Read projected clicks, conversions and CPA.

Understanding the inputs

What each value means, why it matters, and a typical range — so you can fill in the calculator with confidence.

Ad Spend

The total money put into paid advertising over a period.

Why it matters:
With revenue and margin it tells you whether advertising is actually profitable.
Typical range:
Set by budget and target return on ad spend.
How it affects results:
  • Higher: More reach but more money at risk if campaigns underperform.
  • Lower: Less reach but lower risk.

Common mistake: Judging ad spend without tracking the revenue and margin it produces.

Cost Per Click (CPC)

The average amount you pay each time someone clicks your ad.

Why it matters:
With conversion rate and order value, it decides whether paid traffic is profitable.
Typical range:
From a fraction of a dollar to several dollars, depending on industry.
How it affects results:
  • Higher: More expensive traffic.
  • Lower: Cheaper traffic.

Common mistake: Optimizing for low CPC while ignoring whether those clicks convert.

Clicks

The number of times people clicked your ad or link.

Why it matters:
Clicks bridge impressions and conversions and drive cost in CPC campaigns.
Typical range:
Impressions multiplied by CTR.
How it affects results:
  • Higher: More visitors, and usually more spend.
  • Lower: Fewer visitors.

Common mistake: Counting all clicks as unique visitors; some are repeats or invalid.

Conversion Rate

The percentage of visitors or leads that take the desired action, such as buy or sign up.

Why it matters:
Small improvements multiply across all traffic, often the cheapest way to grow.
Typical range:
1% to 3% for many e-commerce sites; varies widely by channel.
How it affects results:
  • Higher: More sales from the same traffic.
  • Lower: Fewer sales from the same traffic.

Common mistake: Comparing rates across very different traffic sources as if equal.

Click-Through Rate (CTR)

The percentage of people who click your ad or link after seeing it.

Why it matters:
It measures how compelling and relevant your ad and targeting are.
Typical range:
Around 1% to 3% for many search ads; lower for display.
How it affects results:
  • Higher: More clicks from the same impressions.
  • Lower: Weaker ad or targeting; wasted impressions.

Common mistake: Chasing CTR with clickbait that does not convert.

Common interpretation errors

  • Display CTR is far lower than search
  • High CTR that does not convert is not enough
  • Channel and intent vary widely
  • Small sample sizes are noisy

$5$1.00$0.50$0.25
$10$2.00$1.00$0.50
$20$4.00$2.00$1.00

Common mistakes to avoid

  • Using aspirational conversion rates — 2-5% is typical for cold search traffic; landing page quality dominates.
  • Projecting from average CPC when your niche's real CPC is multiples higher.
  • Optimizing to clicks instead of CPA.

Body
Hey r/[subreddit],

I kept needing a quick equity calculator and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard equity use cases (equity, valuation, investment, cap table) and links out to the formula + worked examples if you want to learn the math.
