MeidokonWiki:

This is calculated after-the-fact. The final effective exchange rate that I got is based on initial starting cash, and then on subsequent transactions made against my bank account and credit card.

All dollars are Australian.

Now calculate the weighted average. I'll just be lazy and do Sum(all JPY values) / Sum(all AUD values)

    170,000 + 40,000 + 40,000 + 20,000            270,000
------------------------------------------  ==  --------------  ==  82.514
1995.05 + 490.22 + 481.80 + 243.40 + 61.70          3,272.17


For reference, increasing the denominator by a few AUD, to 3275, reduces the exchange rate to 82.443
