For example, we are based in Canada and use a PLAN foreign exchange rate, not the Hubspot FX rate. And we adjust that plan rate annually. Because of this, we need a means to translate foreign currencies to our currency that uses the plan rate for current and historical purposes. So, we don’t want to have a single # hardcoded in calculations to create a “local Canadian view”. For the moment, we’ve got hardcoded values in our calculations to create our own customized properties. But the formulae will get complicated as the years go by (“If year = 2025, then use rate 1.25 … else if = 2026, then use 1.42 … else if = 2027” etc). If we have a means to use variables, then we can code the exchange rate formulae once, and then we just have to update the “conversion table” (or whatever) at the beginning of a new year.
