That's probably more years than any calculator will give you, but don't forget that, by definition, there's a fifty-fifty chance that you'll exceed your actuarial life expectancy. If you have only enough money to last that long, then there's a good chance you'll outlive your funds. Screen 2 asks about your current income and assumes a 3 percent annual increase rate that you can adjust if you like. It also calculates how much money will need during retirement based on the assumption that you'll want 70 to 80 percent of your current income, and the link reading Explain can tell you more. Think twice before you accept the 70 to 80 percent figure.
Many people find that they've underestimated their retirement needs.
It's probably more realistic to assume that you'll want at least the same income. Screen 3 estimates taxes and inflation. You should assume that your post-retirement tax rate will be the same as it is now. Quicken automatically assumes a 3 percent inflation rate. Go ahead and stick with that, but be aware that it might be unrealistic because it's based on recent years, during which inflation has been very low.
