Nine calculators for the numbers that decide whether marketing pays for itself. No sign-up, no email required, nothing stored — the arithmetic runs in your browser.
Cost Per Lead & ROI Calculator
Work out what an enquiry is actually worth to your business, and what you can afford to pay for one.
Open the tool →Marketing Budget Planner
A sensible starting budget based on your revenue and growth goal, split across channels.
Open the tool →Website Health Scorecard
Twelve questions that tell you whether your website is helping or quietly costing you enquiries.
Open the tool →ROAS Calculator
Return on ad spend, ad cost as a share of revenue, and the profit left afterwards — because a 4× return on a 20% margin still loses money.
Open the tool →Break-Even ROAS Calculator
The exact return at which advertising stops costing you money. Every target should start here.
Open the tool →CPM, CPC & CTR Calculator
Spend, impressions and clicks in — cost per thousand, cost per click and click-through rate out.
Open the tool →Customer Lifetime Value Calculator
What a customer is worth across the whole relationship, and the most you can afford to pay to win one.
Open the tool →UTM Link Builder
Tag a link so Analytics tells you where the visit came from. Lower-cased and cleaned automatically.
Open the tool →Title & Meta Description Checker
See how a page will look in Google before you publish it, and whether either line gets cut off.
Open the tool →The numbers most owners cannot answer
Almost every conversation we have about marketing budget stalls in the same place. The owner knows roughly what they spend and roughly what comes in, but cannot say what one enquiry is worth, what a sensible budget would be, or whether their website is the thing holding everything back.
Without those three, every decision after them is a guess. "Six hundred a month for Google Ads" is either obviously right or obviously wrong once you know a customer is worth $2,000 in margin and one in four enquiries closes — and completely unjudgeable until you do.
These calculators exist because we got tired of doing the same arithmetic on a notepad in first meetings. They are the same arithmetic, done properly, with the reasoning written out underneath so you can argue with the assumptions rather than take them on trust.
Six more were added in 2026 for the questions that came up most often after that: what a campaign actually returned, the point at which advertising stops paying for itself, what a customer is worth over the whole relationship, and how a page will look in Google before it is published.
Where to start
- Start with the enquiry value calculator. It gives you the ceiling — the most an enquiry can cost before it stops being profitable.
- Then run the budget planner. It gives you a defensible starting range and a split across channels.
- Then score your website. If it scores badly, the budget from step two should go into fixing it before any of it goes into advertising.
- Running ads already? Break-even ROAS first, then the ROAS calculator against last month's figures. The two together tell you whether to scale or stop.
What they cannot tell you
None of them know your market. Two identical businesses in different cities can face costs per click that differ threefold, because the price is set by whoever else is bidding. None of them know your capacity, either — a brilliant cost per enquiry is worthless if you cannot deliver the work.
And none of them replace looking at your actual accounts. They produce a considered starting point, which is a long way ahead of a guess and a long way short of a diagnosis.
