Honour Payment

Mark's Spreadsheet is the result of many years of work and it incurs real expenses to host, develop and support. As we want to avoid the hassle of license keys and copy protection, Mark's Spreadsheet is licensed via an Honour Payment that relies on the trust and goodwill of our users.

How it works

1. Complete the form below to receive an email with instructions for downloading the Spreadsheet.

2. Try the Spreadsheet free for 30 days.

3. If you have found the Spreadsheet to be of value and want to continue using it, visit our payment page to make your annual payment of $50. Your payment entitles you to use  Mark's Spreadsheet for yourself and members of your immediate family for one year.

4. Repeat each year when the Spreadsheet is updated with new features and the latest tax information.

System Requirements

Mark's Spreadsheet requires Microsoft Excel 2010 or newer or Microsoft Excel 365 (desktop version) on a PC or Mac with macros enabled. Mark's Spreadsheet requires Excel macros for its powerful optimization functions - other spreadsheet programs (e.g. Google Sheets, Numbers, Open Office, LibreOffice) and Microsoft 365 for the web will not work.

Note that some IT departments may disable the ability to use the macro feature of Microsoft Excel on work computers.
