What we're working on

  • Compare investment strategies. See different ways of investing side by side on your plan, each with your sustainable monthly income and the chance your money lasts. A bucket strategy keeps two years of spending in cash and the next five in bonds, with the rest in stocks. You spend from the cash. After a good year for stocks, some stocks are sold to refill the cash and bonds. After a bad year, bonds refill the cash, and stocks are sold only if the cash and bonds have both run out. A barbell keeps 80% in cash earning short-term interest rates and 20% in stocks, with no bonds. A fixed mix keeps the same share in stocks and bonds every year, such as 60% stocks and 40% bonds. You'll also be able to pick an age to switch from one strategy to another.
