## Frequently Asked Questions

**Is it a one-time payment or monthly/recurring?**

One-time payment, yours forever.

**Does it work in my version of Excel?**

All calculators works in all versions of Excel from Excel 97 to Excel 2016, also including Office 365 and Excel for Mac. Most were developed in Excel 2010 or Excel 2016 and tested in other versions. For older versions you may need to use a different version of a calculator, which is always included.

**Does it work in OpenOffice / LibreOffice / Apple Numbers / other spreadsheet software?**

The calculators may work in some, but unfortunately we can’t guarantee it and can’t provide support for software other than Microsoft Excel. Generally you need your software to support Excel formulas and (with most calculators) macros.

**How do I pay? Is it secure?**

You can pay by credit/debit card or PayPal. All payments are processed by PayPal, but you don’t need a PayPal account to check out when paying with a card.

**I have other questions / need more information.**
