Estimated Monthly Forecast
How This Forecast Is Calculated
Lead definition: A lead is an estimated conversion after an ad click. The calculator does not assume whether that lead is a phone call, WhatsApp enquiry, form submission or another contact method.
Google Ads Budget & Lead Forecast for Small Businesses
Planning a Google Ads campaign can be difficult when you do not know how much traffic your budget might generate. The Cape Portal Google Ads Budget & Lead Forecast Calculator gives small businesses a simple way to model potential impressions, clicks, advertising spend, leads and cost per lead before committing to a campaign.
How the Google Ads Forecast Works
The calculator uses your estimated monthly local search volume, expected impression share, click-through rate, average cost per click and landing-page conversion rate. These figures are combined to produce a planning estimate rather than a promise of campaign performance.
Why Your Google Ads Budget Matters
A Google Ads budget should be considered alongside the number of relevant searches in your service area, the competition for those searches and the quality of the page people reach after clicking your advert. A larger budget does not automatically produce better leads, and a low cost per click does not necessarily mean a low cost per lead.
Improve the Numbers With Real Campaign Data
Once a campaign has collected enough data, replace the initial estimates with your actual CPC, CTR and conversion rate. This makes the calculator more useful as a planning tool because your forecast can gradually reflect the performance of your own business, keywords and service area.
Frequently Asked Questions
Is this a Google Ads cost calculator?
It is a planning calculator for estimating possible Google Ads spend and lead volume. It does not connect to your Google Ads account and does not provide live keyword or auction data.
What is cost per lead?
Cost per lead is the estimated advertising spend divided by the estimated number of leads generated from those ad clicks. It helps you compare the potential economics of a campaign.
Why can my actual results be different?
Actual results can vary because of keyword selection, location targeting, competition, ad relevance, landing-page experience, bidding strategy, search behaviour and the way conversions are measured.
Can I use this for a Cape Town business?
Yes. Use the monthly local search volume that best represents the geographic area and services you are planning to advertise. The model can be used for Cape Town businesses as well as other South African service areas.
