How to set your paid ads budget without throwing money away

There's no one right budget for everyone. But there is a right method to calculate yours. Here's how to get to the number without guessing.

Why "how much do you have?" is the wrong question

A lot of agencies ask what budget is available before understanding the business. The result is a campaign sized to your wallet, not to your goal. The right question is: how much do you need to earn, and what does each customer cost? The budget gets calculated from there.

The method for calculating your ideal budget

Step by step to calculate your budget

1 Decide how many new customers you want per month (e.g., 20 customers)
2 Estimate your close rate on contacts (e.g., 1 in 4 becomes a customer = 25%)
3 Calculate how many contacts you need to generate (e.g., 20 ÷ 25% = 80 contacts)
4 Multiply by the estimated cost per lead (e.g., 80 × $25 = $2,000 in media spend)

Cost per lead varies by niche. A good agency can estimate it based on experience in your segment.

Minimum viable budget by platform

$500–$1,000 Minimum Google Ads spend to start generating enough data
$300–$600 Minimum Meta Ads spend for local targeting with reasonable volume
$1,000+ Combined budget (Google + Meta) for most local businesses

Below these figures, the platforms' algorithms don't have enough volume to optimize the campaign. Starting with too little tends to produce poor results and the impression that "ads just don't work."

Frequently asked questions

Should I increase my budget if the campaign isn't performing?

Not necessarily. If the campaign has conversion or targeting problems, raising the budget just multiplies the waste. Fix what's broken first, then scale.

Does the agency's management fee count toward this budget?

The media budget (what you pay Google or Meta) is separate from the agency's management fee. When calculating your total cost, add both together. A transparent agency makes clear where every dollar goes.

Can I start small and scale up?

Yes, and it's the smarter approach. Start with the minimum viable budget, confirm your cost per lead is at an acceptable level, then scale. Increasing the budget on a proven campaign is far safer than betting big at the start.
