You havent really told us the conditions that apply to the day rate (is it optional and only a guide - doubt it if it is a formal offer, or is it obligatory when you do some days in Eurozone?) If it is day rates over a fixed term (a year?) multiply it by the number of working days in that country you might agree to work with holidays (which you havent told us and would vary with local holidays). Not sure what you or the employers notion of an appropriate exchange rate is (presumably an agreed monthly spot rate) ? You should also look at a cost of living index. So if cost of living is 75 in that country to a UK index of 100 then- you would know you were living like Johnny foreigner if you were not taking it into account (and virtually paying tourist prices) 100- after a year you might have partly assimilated to local culture 90 - after two years (if assimilation was done sensibly by employer/employed/local market etc) you might look at 75Anyway if its the odd day or month it might be simpler to just look at unclaimable expenses and travel times and take the lifestyle as a bonus (or cost if you choose the wrong location).Otherwise I'd do a few basic spreadsheets to remain reasonably competitive, or turn it down.
