When investing for long-term goals like retirement, investment fees can have an enormous impact on your portfolio’s total return. Even fees as low as 1% compounded over 30 years can reduce your nest egg by hundreds of thousands of dollars. That’s why having access to good investment fee calculators is so important – they allow you to quantify the long-term impact of fees and make better-informed decisions about what investments to choose in your 401(k), IRA, or taxable accounts. In this article, we will compare some of the top investment fee calculators available and look at the key features you should consider when picking the best calculator for your needs.
