SigFig's management fee is 0.25% of the assets under management over $10,000. This means that, for example, if you invested $40,000 in an account, then we would charge a fee as if you only invested $30,000. This also means that any accounts under $10,000 are free as along as they are above our $2000 minimum.
Also, we don't charge commission fees, transaction fees, or trading fees. (Note: The funds themselves are low-cost with an average expense ratio of 0.15%.)
