We have found a helpful wedding budget template created by Microsoft.
It is an excel file that can be edited to meet your specific needs; however, you are likely to find it to be adequate as is. It displays your estimated and actual wedding budget costs as you enter them. It also keeps track of your total wedding costs. We hope you find this tool to be quite helpful in your wedding planning. Let us know how you like it!
You can view it and download it here: Free Wedding Budget Planner Spreadsheet
UPDATE (December 2008): We have just created a New and Improved Free Wedding Budget Planner Spreadsheet that we believe will be even more helpful to brides and grooms planning their wedding budgets. Enjoy!
