Bulk Buy & Cost-Per-Serve Calculator Spreadsheet – Decide If Bulk Is Really Better Value (Excel / Google Sheets)

Bulk buying can save money — or waste it. This calculator helps you decide before you buy.

Enter the regular size and the bulk size (price, quantity and number of serves). The sheet instantly shows cost per unit, cost per serve, and the percentage saving (or loss). A simple decision helper then asks the practical questions most people forget: Do you have storage space? Will you actually use it before quality drops? Is the saving large enough to justify the extra cash tied up?

What’s included:

• Instructions sheet
• Calculator sheet – side-by-side regular vs bulk comparison with automatic results and decision helper questions
• Decision Log – record what you decided and later note the outcome so you learn over time

Works in Excel, Google Sheets, LibreOffice and Numbers. No macros. Currency is left blank so you can use your own.

Perfect for anyone tempted by warehouse packs or “special” bulk deals who wants honest numbers first.
