# HOW TO CALCULATE EXCHANGE RATES IN MICROSOFT ACCESS

Posted on 2009-05-14

Hi,
Let me preface my query by saying I am an MS ACCESS Novice.  I see that most people provide just sql code for answers on here.  I need to understand my solution conceptually first so I would appreciate a very laymen's explanation.

I have a database which tracks costs across several countries.  These costs are inputted by the users in local currency, so British Pounds, Polish Zloty, Danish Krone, etc...

I need to convert these costs into Euros.  I am aware the solution involves creating a table with the Euro/Local exchange rates and querying the data entry table with the exchange rate table to get the conversion.  I have my table with exchange rates but cannot get further than that.

All help is very much appreciated.

Regards,

MIchael

How do you identify the 'local' currency?
Is it a field in the cost record?

Firstly, ensure you data structure is appropriate.

I would expect that the table where costs are stores will have the cost in local currency and a field that indicates what currency that cost is

The Currency table needs to have that same currency indicator field, and a value for that currency of 1 and a coilumn to indicate what Euro value 1 of the cost currency is equal to.

You have not indicated how you will deal with fluctuating currency rates.

Assuming we ignore the fluctuations, yo can now create a query that uses both tables and links the two on the currency indicator
Create a field in that query that is Costs*EuroValue - this is the value in Euros. Add in any other fields that you want.

This is the real simple start - you then need to work out what you want to do with this result.

Hi
The costs are directly input in a field in my Cost Table.

The only indicator I have included determining local currency is another field called Country, i.e., UK, Denmark, etc...My currency table has same indicator field.

I have dealt with fluctuating forex by linking an excel sheet using the Microsoft Live FOREX feed function.  So, before I open the access database I have to update the excel sheet.

This is all I need as I am calculating costs / per square foot.  It's  benchmarking database that provides me with various costs across EU, i.e, janitorial, maintenance, security, etc...

Ok, create the query as per my post above, linking country in costs and currency tables

Currency exchange is an extremely dynamic set of variables.  Less than an hour after you start using your table, an exchange rate somewhere can change by a percent or more - which means it is obsolete shortly after you start using it.  That said, I wondering why someone on the west coast wants to convert international currencies into EUR and not USD or CAD - school work perhaps?

http://www.ratesfx.com/rates/rate-converter.html  -  provides an up-to-date currency conversion tool.  From that source at this time 1 Danish Krone or DKK = 0.13 EUR.  What don't you under stand about how many Euro is 19.95 DKK?

GRAYL,

Not sure what the intention of your post was (?).  I know currencies fluctuate as I have to develop outsourced solutions across EMEA.  The purpose of the database is to allow costs to be input in local, convert to euro and provide euro/psm benchmarking.

I'm in LA (lower Alabama) and have tons of EMEA and SAP (South Asia Pacific) currency conversions going on and its not all to/from USD. We deal in 28 currencies.

I think that GrayL thought that this possibly was a school project

Everybody jokingly says its LA (meaning lower Alabama) but its actually upper Alabama, 75 miles south of Chattanooga TN...

When you work with Real Estate square feet and USD are the accepted standards of working, hence, the USD.
