Frequently asked questions
What are site guides?+
Site guides explain how to get the most out of this site rather than teaching a calculation. They cover finding the right calculator, reading and interpreting results, saving calculation runs in your browser, and using the spreadsheet templates alongside the online tools.
Do I need an account to use the calculators?+
No. Every calculator and template is free to use with no signup. Saved calculation runs are stored in your own browser rather than on our servers, which means they stay private to you, but they are also specific to that browser and device and will not follow you elsewhere.
How are the calculators kept accurate and up to date?+
Calculators are built on published formulas, and the guide attached to each one sets out the method and assumptions so you can check the working rather than take the result on trust. Results are estimates for planning. Where figures depend on local rules, provider fees, or tax rates, confirm the final numbers with the relevant authority or provider before acting on them.
