What if you add a little each month?
Adding $25 a month on top of the $2,500 would give about $16,778 after 20 years at 5%, compared with $6,633 for the lump sum alone. Small regular amounts add up.
Keeping the risk in proportion
Higher returns come with more risk. A cash account is predictable but may not keep up with prices. Retirement accounts such as a 401(k) or IRA have tax advantages, and contribution limits that change every year. Interest and gains in an ordinary taxable account can be taxed.
