Ad budget split.
Enter a monthly budget and give each channel a share. See dollars per month, week and day, and the clicks each channel buys at your expected CPC.
Channel budget = total budget x share. A $3,000 monthly budget split 40/30/20/10 gives $1,200, $900, $600 and $300, or $40, $30, $20 and $10 a day over 30 days.

Worked example
A $3,000 monthly budget split Search 40%, Social 30%, Video 20% and Retargeting 10% gives $1,200, $900, $600 and $300. Over 30 days that is $40, $30, $20 and $10 a day, or $100 a day in total. At expected CPCs of $1.50, $0.90, $0.60 and $0.40 the channels buy about 800, 1,000, 1,000 and 750 clicks, 3,550 in all. If monthly revenue is $30,000, the budget is 10% of revenue.
How it works
Channel dollars = total budget x channel share. The shares must add to 100%. Weekly dollars = monthly dollars x 7 / days in the month; daily dollars = monthly dollars / days.
Expected clicks = channel dollars / CPC. This is a planning estimate from the CPCs you enter. Real CPCs move with competition and quality, and not every channel is paid per click.
Budget as a percent of revenue = budget / revenue x 100. For context, Shopify's marketing budget guide cites Gartner as putting the average marketing budget for businesses in 2022 at just under 10% of total business revenue, and says yours may be lower or higher depending on needs and goals. That is all marketing, not only ads, so it is a loose reference rather than a target.
The calculator does not recommend a split. It turns the split you choose into daily numbers you can set in each platform.

FAQ
How should I split my ad budget between channels?
There is no universal split. Start from where your customers are and your past results, then adjust. This tool turns the split you choose into dollars per day.
How do I convert a monthly budget into a daily budget?
Divide the monthly budget by the days in the month. $3,000 over 30 days is $100 a day.
What percent of revenue should go to advertising?
It varies by business. Shopify cites Gartner at just under 10% of revenue for all marketing in 2022, but that is an average across businesses, not a rule.
Why must the shares add up to 100%?
Otherwise part of the budget is unassigned or over-assigned. The calculator tells you the current total so you can adjust.
