How much should a startup spend on Google Ads to start?
Most first Google Ads budgets are guesses. A simple calculation gives you a number you can defend.
- What's a good starting budget for Google Ads?
- Is $1,000 a month enough?
- How long should we test?
Set your first Google Ads budget from the result you need, not a round number. Decide how many conversions make a clear test, estimate your click-to-conversion rate and look up the cost per click for your keywords. Conversions needed divided by conversion rate, times cost per click, gives the budget. Google suggests judging bidding over 30 days with at least 30 conversions, so a test usually needs that much data.
| Input | Value |
|---|---|
| Conversions needed for a clear result | 30 demo requests |
| Click-to-demo rate | 3% |
| Clicks needed | 30 ÷ 0.03 = 1,000 |
| Average cost per click | $12 |
| Test budget | 1,000 × $12 = $12,000 |
| Over 3 months | About $4,000 a month |
If the number is too high
Narrow the keywords to the highest intent, use a cheaper conversion as an early signal (such as a pricing page visit plus form start), or test a smaller geography. A budget too small to reach any result is the most expensive option, because you learn nothing.
Budget the rest of the test
Include landing page work, tracking setup and someone's time to manage the account. Those often cost as much as the first month of clicks.
- A round-number budget with no calculation.
- A budget too small to reach any conversions.
- Testing across many countries at once.
- No landing page built for the test.
- Stopping after two weeks.
- Budget calculated from conversions needed.
- High-intent keywords first.
- A pass mark set before launch.
- Tracking checked before spend starts.
- A 60 to 90-day window.

Is $1,000 a month enough for Google Ads?
It can be for low-cost keywords and a narrow test. For competitive B2B keywords it often buys too few clicks to learn.
Should we hire someone to run the test?
If nobody in-house has run search campaigns, a short engagement with a specialist saves wasted spend.
What counts as a conversion?
A demo request or qualified lead, ideally confirmed in your CRM.
