PM on it's way.
Had an idea which I used in Excel for my previous two trips..
In the spreadsheet I made the following columns that was used for budget and actuals
Date | Category | Item | Paid To | Amount | Customs |
Before I left I filled in a heap of stuff for example
5 May | Food | Tips | Fancy Restaurant | $20 | N |
5 May | Spending | General | Necklace | $100 | Y |
These items was what I had budgeted to get. As the trip progressed each night I would sit down and update these amounts into actuals, and total each day. Perhaps adding lines.
I also have $100/day to spend $1000 over 10 days that isn't yet listed above. At the end of day 1 I have $50 of it.
Day 2 the spreadsheet updates letting me know that I have $950 remaining over 9 days or $105 per day. The opposite would occur if I went the other way!
Same on day 3 etc.
Same can occur with the planned money. Using the above at the end of day 1, of the $120 above I had only spent $100, the remaining $20 would be evenly spread over the non-planned money for the remainder of the trip.
I hadn't started converting my sheet over to numbers yet, but am happy to help. While my Excel skills are really good, learning where things are in numbers leaves me a little stumped at times!
Also, coming from Australia and dealing with exchange issues, it used that conversion along the way! I believe the Au and Canadian are very close at the moment.
I'll also try it here (that part) and can forward to you if you like to include in your spreadsheet.
