How to use this calculator

Enter your target revenue, average order value, expected conversion rate, and average CPC. The calculator estimates the budget required to reach your sales goal and shows the daily budget using a 30-day planning period.

What the result means

The result shows the estimated ad budget needed to reach your target revenue under the current CPC and conversion assumptions.

Required conversions = target revenue / AOV; required clicks = conversions / conversion rate; required budget = clicks × CPC.

If the required budget is too high, improve conversion rate, reduce CPC, or increase average order value before scaling.

Example calculation

If your target revenue is $50,000, AOV is $250, conversion rate is 4%, and CPC is $2.50, you need about 200 conversions, 5,000 clicks, and $12,500 total budget.

Tips for better results

  • Improve landing page conversion before raising spend.
  • Lower CPC with better Quality Score and keyword structure.
  • Use budget sensitivity to test conservative and aggressive scenarios.

FAQ

How much Google Ads budget do I need?

Estimate the required budget by dividing your revenue target by average order value, converting that into required conversions, then estimating clicks from your conversion rate and CPC.

What daily budget should I set for Google Ads?

Use daily budget = required total budget divided by campaign days. If the daily amount is too high, improve CPC, conversion rate, or average order value before scaling.

How much should a small business spend on Google Ads?

A small business should start with a budget large enough to generate statistically useful clicks, then compare CPC, conversion rate, and CPA against profit targets.

How much budget do I need to generate 100 leads?

Multiply the clicks needed for 100 leads by your average CPC. Required clicks equals 100 divided by your landing page conversion rate.

How do I calculate Google Ads budget from revenue goals?

Revenue goal divided by AOV gives required sales. Required sales divided by conversion rate gives clicks, and clicks multiplied by CPC gives the required ad budget.
