Error in the results
As you increase the Withdrawal rate, the number of years required before you can retire decreases. There must be an error in the math, as that makes no sense at all.

Current Income not clear
Should read like after tax income (without looking at assumptions this could create poor calculations)

Canada RRSP dewduction on gross pay
HI!
In Canada, the taxes can be deducted if you make a contribution to a RRSP account. This muddies up the easy math of "Net take home pay" because my take home pay includes a tax return AND savings in a RRSP.
Would be nice to sort this out more efficiently. Right now I don't see how?!

ROI Calculation
I'm sure the ROI calculation is correct, I'm just not fully understanding how you came to the conclusion that you did. If I bring in 20k and can save 50% (with a savings rate of 5%), surey the ROI after the first year is 500 rather than the displayed 250?

your chart is flawed
as i change the withdrawal percentage [see examples 3%  7.7, 4%  4.2, 5%  1.8, 6%  0.0] the more i withdraw, the less time i have until retirement??!? how TF does that make sense... unless i am missing something

Able to include funds already saved
If I've already saved X, that should be included as generating returns.

Manual years to retirment
Instead of inputing "Current savings rate" can you input "desired years to retirment" and then it would give you all the figures needed to get that target?

Allow a different postretirement annual expense
Since many of us plan on retiring abroad thus greatly reducing our annual expenses (and even if we don't move, many of us do reduce expenses a lot), the calculator should not assume by default that the current expense rate is also the postretirement expense rate.

Current Expense Question
Question: Should Current Annual Expenses include the taxes you pay on your paycheck? Your tax rate will go down when you don't have pay check when you retire, so including those taxes seems like over stating the taxes when you are retired.

Take income tax into consideration
Income tax typically higher during working years. Where do you put it? Expenses? If so, this over estimates time needed by assuming your expenses including high income tax during working years will be the same in retirement.

Make a box with tax on investments
I live in Denmark where we pay 28 % in tax on investment gains in the stock market up till the first 48K (in DKK) we gain, and there after 48 % on any gains above 48K. I assume that we danes have to hit a 8 % safety margen before we can retire. Is it possible to make som boxe where we can enter tax on investment and then calculate?
Thx

Bug in calculation
I put in the following values:
Current annual income: 434782
Current annual savings: 334782
Current annual expenses: 100000
Current savings rate: 76% (calculates automatically)
Current portfolio value: 850000It says I can retire in 4.3 years. If I add ONE dollar to annual income and recalculate it says i can retire in 3.8 years with a 78% savings rate. That's a huge jump for 1 dollar.
As another example if I put in 400,000 for income it now says I can retire in 4.1 years. Meaning that making over 30,000 less would result in an earlier retirement date.

add the ability to change expenses after retirement.
Our expenses will be way lower during retirement so this calculator doesn't really work for us.

Add the ability to insert future periods where additional income kicks in.
For instance:
I have a defined benefit work pension starting at time X
I have federal pension starting at time Y
I have a lump sum injection at time Z
That would make this calculator even more wicked!31 votes

Allow for negative return on investment
In times of a 2% inflation goal of the European central bank and roughly 0% interest in most places you should allow for a negative interest rate in your formula.
Having a negative interest rate leads to a lot not NaNs and weird diagram.3 votes 
Allow for Ages & IRS Rules
For example if I put in my current savings, portfolio value and Income data  I derive at 7 more years until retirement. However, given my assets are in a 401k they cannot be touched without penalty until the year in which I turn 55. So, being 35 yrs old  42yrs old is not a viable option unless it can account for tax deferred and taxable account portfolios separately. I would think this would be the case for most Americans saving in a 401k or tax advantaged retirement account. It would be great if the IRS rules could be…
