Facebook Ads Budget Calculator
Estimate your Facebook ads budget, clicks, leads and cost per result based on your campaign goals and performance assumptions.
Overview
This Facebook Ads Budget Calculator helps you estimate how much you may need to spend to reach a target number of clicks, leads or sales. Enter your expected cost per click, conversion rates and campaign length to get a simple budget estimate for planning purposes.
How it works
The calculator starts with your campaign goal and works backwards to estimate how many clicks are needed. For clicks, the target result is the click total. For leads, it divides your target leads by your landing page conversion rate. For sales, it divides your target sales by both your click-to-lead conversion rate and your lead-to-sale rate. It then multiplies the required clicks by your average cost per click to estimate total spend, and divides that by the number of campaign days to estimate a daily budget.
