These figures are based on averages from the ad accounts we run, so treat them as a starting point, not a promise. Our default cost per enquiry is the typical figure across those accounts, so it sits above the figures in our case studies, which show our best campaigns.

How it works

How this is worked out

01

The enquiries you need

Take the customers you want each month and divide by how many of every 10 enquiries become customers. Eight customers at 25% means 32 enquiries.

02

What the goal costs

Multiply those enquiries by the cost per enquiry for the monthly spend the goal needs. Divide by 30.4 days (365 days over 12 months) and round to the dollar for a daily figure.

03

Never under the minimum

We recommend the bigger of that daily figure and the minimum we publish: $30 a day on Google, Meta and TikTok, $25 a day on ChatGPT. A month is the daily figure times 30.4, every 4 weeks is times 28, and management from $800 every 4 weeks is added on top.

Questions

What people ask about the Enkindle ad budget calculator

How is the recommended daily budget worked out?+
We divide the customers you want by how many of every 10 enquiries become customers, to get the enquiries you need. We multiply that by the cost per enquiry, divide by 30.4 days (365 days over 12 months) and round to the dollar. If that comes in under the minimum we publish for the platform, we show the minimum instead.
Why won't the calculator go below $30 a day on Google or Meta?+
A goal this small still needs $30 a day (about $913 a month) for the ads to learn, so that is what we recommend. $15 a day (about $456 a month) is the absolute floor for smaller businesses, and we don't recommend it.
Where does the default cost per enquiry come from?+
The $32 on Google and $15 on Meta are the typical figures across the accounts we run, measured over the last 90 days. They sit above the figures in our case studies, which show our best campaigns. We hold no typical figure for TikTok or ChatGPT, so add your own to see the goal maths there.
Is the ad spend included in your management fee?+
No. Ad spend is paid to the platform from your own account. Our management is from $800 every 4 weeks on top, GST included, and custom quoted to what you're after.
Why does it ask what margin I keep?+
To check the numbers stack up. We compare the cost per customer with the most you can afford to pay for one, which is the sale value times your margin. If the cost per customer is higher, the calculator says so. Leave the margin blank and we use the full sale value.
Is the estimate a promise of results?+
No. It is an estimate based on our typical results, not a promise. Industry and location aren't in the maths because we hold no measured figure for either, so we talk those through on a call.
