Answer a few plain questions about your business and your costs, and get a straight answer in money — with an honest note on how far to trust it. No spreadsheet to build, no consultant to hire, no software to install.
Four questions every organisation weighing up cloud has to answer, and usually answers on instinct.
Before any maths. Steady demand, sensitive data or critical systems at scale are where cloud most often disappoints — and the tool tells you that instead of selling you on it.
Both options side by side over your horizon — including the three costs people routinely forget: getting back out again, training, and compliance.
Cloud costs run over and gains under-deliver. You see the same case with costs 20% higher and gains 30% lower — usually the most useful number on the page.
It checks its own answer against the quick sum you would do in your head. When that would have got you to the same place, it says so.
About ten minutes, start to finish.
About your setup, how much your workload swings, what data you hold, and what happens if it all stops for a day. Plain English, no jargon.
Your current costs and a cloud quote. Leave blanks where you are unsure — the app counts them and tells you how much that weakens the answer.
One figure, one recommended action, and a printable business case that discloses its own assumptions for your board or lender.
This is not a claim about our policies — it is how the software is built. Everything is calculated inside your own browser. There is no server to send anything to.
The page declares a Content-Security-Policy of connect-src 'none', so the
browser itself blocks any network request the page might attempt. The guarantee is
enforced by the software rather than promised by us.
No account. No upload. No cookies. No tracking. Disconnect from the internet after the page loads and everything still works. What you type here is your cost base and your margins — the most sensitive numbers in your business, and precisely why there is nowhere for them to go.
Nothing exotic. Estimates are fine — the app grades how complete they are and adjusts how confidently it answers.
| You need | Example |
|---|---|
| Your yearly IT running cost | 48,000 |
| A cloud quote, per year | 31,000 |
| Any big spend coming up | 25,000 |
That is the minimum. Add setup costs, exit charges, expected gains and your margin, and more of the answer unlocks. Full guide →
It will not benchmark you against your peers. No credible public dataset of cloud costs and realised savings at this size appears to exist. Rather than fabricate a comparison, the app offers none — and suggests you ask where the figures came from whenever a tool does.
It will not price the unmeasurable. Agility, resilience and staff skills are real and often decisive. They are deliberately kept out of the money total, because inventing numbers for them is how business cases turn into fiction.
Implements the cloud suitability and return-on-investment method of Misra & Mondal (2011, Mathematical and Computer Modelling), as worked through in Lynn, Mooney, Rosati & Fox, Measuring the Business Value of Cloud Computing (Palgrave, 2020), extended with a compliance-cost layer so data-residency and regulated-sector overheads are priced in rather than ignored.
Unusually, the app measures itself against the obvious shortcut — comparing running costs alone — and tells you when the full exercise did not change the answer. It also states plainly that the published method was demonstrated on a single company, so you know exactly how much weight it can bear.
