Budget = revenue goal divided by your target return on ad spend (ROAS). The net line checks the plan against your margin: if gross profit on the new sales does not cover the ad budget, your target return is too low for your margin.

Budget with a plan, not a guess

The right ad budget is not a fixed number; it follows from the sales you want and the return you need on each shilling spent. A target return on ad spend, say four shillings of sales per shilling spent, turns a revenue goal into a budget.

The important check is your margin. If the gross profit on the new sales does not cover the ad budget, the campaign loses money even if it hits its sales target. This calculator does that check so you do not chase revenue that costs more than it earns.

Worked examples

Want KES 300,000 in sales at a 4x return.
Budget KES 75,000; at 35% margin, gross profit KES 105,000 covers it.

Frequently asked questions

How do I set an advertising budget?

Divide the extra revenue you want from ads by your target return on ad spend. If you want KES 300,000 in sales at a 4x return, the budget is KES 75,000. Then check it against your margin.

What is return on ad spend?

ROAS is the sales generated for each shilling spent on ads. A 4x ROAS means four shillings of sales per shilling of ad spend. Your target ROAS should comfortably exceed the point where ads break even on your margin.

Why does margin matter for ad budget?

Because revenue is not profit. If your margin is thin, you need a higher return on ad spend to come out ahead, otherwise the cost of the ads eats the profit on the new sales.

Should I spend a fixed percentage of revenue on ads?

A percentage rule is a rough starting point, but tying the budget to a target return and checking it against margin is more reliable, because it links spend to the profit it must produce.

How does Veira help?

Veira shows your real margins and which sales come from promotions, so you can set a budget that your margin can actually support and measure the return.
