Vs subscriptions
Reference Card vs the monthly bill
On Reference Card:
The calculation aisle is stacked with subscriptions: Microsoft 365 at $99.99 a year, or $9.99 a month. The Reference Card is one HTML file that does the honest working core of what those tools sell, once, for the price of a Swiss Knife.
The bill you were quietly paying
Name the actual products and the arithmetic stops being abstract: an ad-funded web calculator (free, and paid for with your attention and your inputs), a paid spreadsheet template (bought once, lost in a Downloads folder), Microsoft 365 ($99.99 a year, or $9.99 a month: the arithmetic engine you already rent, suite and all). An average reckoners stack lands at $8 a month, forever.
Run that out five years and Microsoft 365 costs $500, Microsoft 365 costs $500. A Swiss Knife, with the Reference Card folded in beside up to eleven other tools, is $95, once.
One year of Microsoft 365 at $99.99 costs more than a Swiss Knife at $95. Every year after that is pure savings on this category.
What the Reference Card replaces cleanly
Some knowledge you do not memorise; you keep it where you can look it up in four seconds. That is the working shape most subscriptions in this category are wrapped around; the Reference Card delivers it without the wrapper.
Concretely: an ad-funded web calculator would keep the inputs, the arithmetic, and the result on its own servers, behind its own login, on its own pricing schedule. The Reference Card keeps the same inputs in a file on your disk — same shape of work, no monthly line on the card.
You keep the workflow. You lose the login, the sync outage, the price hike email, and the export deadline.
What you honestly give up
Team collaboration in real time. Auto-import from third-party APIs. A mobile app that pings you. an ad-funded web calculator does those things and does them properly; if any of them are load-bearing for how you work today, keep paying an ad-funded web calculator — the Reference Card is not trying to compete on those fronts.
Most people, honestly, were paying for features they did not use. The Reference Card is what remains when you strip that back to the tool.

Questions people ask
How does the cost compare to an ad-funded web calculator?
Microsoft 365 runs about $500 over five years and Microsoft 365 about $500. One year of Microsoft 365 at $99.99 costs more than a Swiss Knife at $95. A Swiss Knife folds the Reference Card in with up to eleven other tools for $95, once, and there is no year two.
Is the Reference Card a like-for-like replacement for an ad-funded web calculator?
For the working core — the inputs, the arithmetic, and the result — yes. For free, and paid for with your attention and your inputs, no. We would rather say that plainly than sell you a switch you'll regret in a fortnight.
What if my needs grow past a single file?
Excellent problem. Keep the Reference Card for what it does well; add a specialised SaaS on top only when you have a specialised need. Nothing here locks you in — it is a file.
Can I import my current data?
The Reference Card is deliberately hand-entered. Two minutes of typing on Monday keeps you closer to your own calculation than an integration ever will.
The subscription was renting the arithmetic. Buy the arithmetic instead.
