This is what I do. Rather than keep track of the interest individually in Quicken, I just enter each bond purchase, and then use savings bond wizard to tell me the total interest I would earn if I were to cash in all my bonds. Then I enter this as "interest earned" for the current month, of all bonds in aggregate. This allows me to see the total return for all the bonds in Quicken, and get a feel for my net worth. But I just use SBW to see the breakdowns when I want. This way I only update one value each month.For example, once the month ends, I delete the $100.29 interest (for all the bonds) from the previous month, and make a new entry for $103.12 for this new month, rather than adding $3 in new interest.
