"How much should we spend on ads?" is easier to answer once you know a few numbers about your business. Here is a practical way to build a budget you can justify.

### 1. Know what a customer is worth

Estimate the average value of a customer: the first purchase, or better, the gross profit over the time they typically stay with you. A service with repeat clients is worth more than a one-off sale.

### 2. Decide what you can pay to acquire one

From that value, decide the maximum you can spend to win a customer and still make a profit. This is your target cost per acquisition.

If your sales process converts a share of leads into customers, you can work back to a target cost per lead. For example, if one in four leads becomes a client, you can afford to pay up to a quarter of your maximum cost per customer for each lead.

### 3. Estimate the volume needed to learn

Ad platforms and you both need data. Look up typical click costs for your keywords or audience, and estimate:

- Clicks needed to generate a meaningful number of conversions
- The resulting monthly spend

If that number exceeds your budget, narrow the focus: fewer services, smaller areas or one channel.

### 4. Plan a learning phase

The first weeks are for learning which keywords, audiences and messages work. Expect higher costs at first. Set a defined test budget and duration, and agree in advance what result would justify continuing.

### 5. Split by goal and channel

A typical split:

- **Capturing demand** from people already searching, such as search ads
- **Creating demand** with social and video ads
- **Retargeting** people who visited but didn't convert
- **Testing** new channels or offers

New businesses often prioritise capturing existing demand first, because those visitors are closer to buying.

### 6. Account for seasonality

Increase budget when demand peaks and scale back in quiet periods. Past sales data and search trends help predict both.

### 7. Review monthly

Compare cost per lead and per customer with your targets, then move budget towards what works.

Our [paid advertising](https://oravol.com/services/paid-advertising) service starts with this calculation, so spend is tied to business results from the first month.

## Questions

### Is there a minimum ad budget?

Platforms allow small budgets, but a budget too small to generate enough results makes it hard to learn what works. Estimate how many clicks and conversions you need to judge a campaign.

### Should agency fees be included in the ad budget?

Plan them separately, so you know exactly how much goes to the platforms and how much to management.
