ExcelCalcs is a club whose members share an interest in making calculations with MS Excel. Members submit calculations which are reviewed by us and published if we think they will be of use to our community. You can discuss any calculation with the author by adding a comment on the download page as these are automatically forwarded to the author's registered email address. We charge members an annual subscription fee to cover administration, development and hosting costs. We offer 50% discounts to academic members and free membership to site contributors
. Calculation previews show what each calculation contains but we do not sent out calculations for trial purposes.
