Scenario comparison

Pessimistic
50%
Realistic
120%
Optimistic
240%

Pessimistic halves your conversion rate and close rate; optimistic multiplies them by 1.5×.

Figures are projections based on your inputs and are for planning purposes only. Actual results depend on campaign quality, competition, seasonality, and many other factors. Codesky accepts no liability for decisions made based on these projections.

How the PPC ROI Calculator Works

Plug in your numbers

Drop in your monthly ad spend, average cost per click, landing-page conversion rate, close rate, average customer value, and gross margin. Every input has a hint with realistic UK benchmarks so you are not guessing.

See your projected returns

We translate your numbers into projected clicks, leads, customers, cost per lead, gross profit, and a clear ROI percentage - so you can see what is on the table before you spend.

Stress-test the assumptions

Compare pessimistic, realistic, and optimistic scenarios side by side. If the numbers still stack up when you halve your conversion rate, you know the case for spending is genuine.

Want us to hit these numbers for real?

We manage Google Ads and Microsoft Advertising for UK businesses - transparent reporting, no account lock-in, and fees based on scope rather than a percentage of your ad spend. You keep the account, you keep the data.
