What is Betterment and how does it work? Betterment is a smart money manager and the largest independent online financial advisor that serves one purpose: to help you make the most of your money. Betterment helps you manage your money through cash management, guided investing, and retirement planning. Betterment Checking works like a conventional checking account, complete with a Visa debit card. Betterment Login Checking charges no maintenance fee and zero overdraft fees, and it reimburses all ATM charges. Account balances are held by nbkc bank, which provides up to $250,000 in FDIC insurance for your cash. In the main menu, click “Settings”. Then, at the top of your screen, select “Accounts”. Your Betterment accounts will show on your screen.
