Calculation assumptions and limits

Contributions are made at the end of each month. The annual rate entered is converted to a monthly rate and stays constant. The calculation excludes fees, taxes and inflation. Actual returns fluctuate and investments can lose value. This is not a market forecast, a specific product or an investment recommendation. FLOW does not move or invest money.
