Every calculator, unlimited
The whole range, as often as you like, for as long as you like. No counter, no cap.
What you get
Every calculator, free
Open any CalcStudio calculator and use it straight away. Create a free account and the preview limit goes for good - unlimited calculations, and your results to print or download.
No card requiredNo subscriptionUnlimited with an accountExports included
Included with your free account
The whole range, with nothing held back
There is no upgrade to reach and no part of a calculator kept behind a wall. An account simply removes the preview limit.
Print, save and download
Take a full PDF or a CSV of any result away with you - schedules, charts and all.
Maintained and up to date
Rates, rules and models are looked after so you are not rebuilding calculator logic yourself.
Nothing to cancel
No card, no subscription, nothing running down in the background. An account and that is it.
On your own website
Put a calculator on your site too
Running our calculators on your own website comes with your account as well - there is nothing extra to buy. You get a snippet to paste in, styled with your own branding, and it works for your visitors without any of them needing an account.
Each snippet carries a code that ties it to your account, and it runs only on the websites we have approved with you - so nobody else can put your calculators somewhere you did not choose.

Upcoming Calculators
We are building a second range for the harder questions - the ones where the answer is not a single number but a call between real options, worked through properly. It is a separate product, and it is not here yet.
It will be a paid range. Using one will mean signing in to your account and buying it first - what it will cost has not been settled, so there is nothing to quote here yet.
Nothing about the free calculators changes when it arrives. They stay exactly as they are: the whole range, free, for everyone with an account.
Create your free account
Your account is how you will hear about it - there is no separate list to join.
Built on the same models
The same maths and the same care as the calculators you already use.
For the bigger calls
Where several paths need comparing side by side before you commit to one.
An account, then a purchase
You will sign in and buy it before you can use one. The calculators you have today stay free.
