"fewer" is number, "less" is degree.

just a grammar tweak. not trying to be a jerk, just noticed it.

Please fix it. This site is great!

I think something's wrong with the time-until-retirement estimate, or there's something i'm misunderstanding.

I entered $100k income, $75k expenses, and $1m portfolio, and got this result:

https://networthify.com/calculator/earlyretirement?income=100000&initialBalance=1000000&expenses=75000&annualPct=5&withdrawalRate=4

It looks like the ROI reaches $75k shortly after 6 years, but the time-until-retirement is over 9 years. The table of figures stops updating some but not all of the columns after 6 years. A glitch?

I think I've found a bug: although I probably strectched the expected parameters. The error seems to be that the table at the bottom has mostly empty cells. My figures were
http://networthify.com/calculator/earlyretirement?income=204298&initialBalance=1500000&expenses=135096&annualPct=22&withdrawalRate=4

This graph will underline the importance of the saving rate independent of income.

It'd be great if you had the option to select the number of years you wish to save at that rate, and highlight the year you can retire at. I'd like to see when I can hit FIRE, with boosted expenses after I retire. (Spend only 20K leading up, but see where I can spend 40K in RE on the chart)

It'd be fun if you could enter your current age and it spat out the age you would retire, instead of the number of years till retirement!

while it is nice in theory to be able to live entirely off of the returns your portfolio generates, it is impractical for 99 percent of the population. Most people will need to plan on some run-down of assets in their later years, which substantially reduces the assets one needs to retire. If you want, you could make your calculator include a "desired bequest" amount in order to preserve some capital for future generations.

i think that ROI isn´t calculated well
