You will find the savings withdrawal calculator to be very flexible. While it is most frequently used to calculate how long an investment will last assuming some periodic, regular withdrawal amount, it will also solve for the " Starting Amount", "Annual Interest Rate" or "Regular Withdrawal Amount" required if you want to dictate the duration of the payout. That is, if the withdrawals must last for say 25 years, it will calculate one of these other three values.

Enter any three values and enter a "0" (zero) for the one unknown value.

A note or two about "Compounding Frequency". Selecting he "Exact/Simple" option sets the calculator so it will not compound the interest. Also, the exact number of days between withdrawal dates is used to calculate the interest for the period. The "Daily" option uses the exact number of days between dates, but daily compounding is assumed. (The interest earned each day is added to the principal amount each day.) The "Exact/Simple" compounding option is the most conservative setting. That is, using it will result in the lowest future value. Daily compounding will result in nearly the greatest future value (except for "Continuous Compounding".

The other compounding frequencies are based on periods of time other than days. Each period is assumed to be of equal length for the purposes of interest calculations. That is, assuming a balance of $10,000, the interest earned for January will be the same interest earned for February given the same interest rate.

hello! So I am not sure on how to use it. Here is the situation to solve. for example, I have 10.000 of savings. Let’s say anual interest is 4%. I would like to know the final amount of money I would have after 60 months, with the same anual interest but making a withdrawal of 20 every month for those 60 months. Is that possible with this calculator? Let me know please what to enter and in which cell. Please

Best regards

Since you have no unknown values and you want to know the balance at the end of 60 months, just input what you told me, and click on the "Withdrawal Schedule." Enter the 10,000 in "Savings on Hand."

Nicolas says:

Hello! I find this calculator very helpful but it is kind of not working, I keep getting the NaN on the interest and net change column.

Karl says:

Oh, that’s not good. NaN stands for not a number. I just started to see that this past weekend and I think I know what the reason is. I should have it fixed in a week (+/-) if I’m right.

Just in case it’s something else, can you tell me your inputs?

What I think is happening is there’s a problem when the last withdrawal is in January (that was the issue with the Investment Calculator). If that’s the case, you can try to shift your calculation by one month in either direction. The numbers will be accurate, just off by 1 month.

Karl says:

I’m able to duplicate the problem, so I don’t need an example. For me, it works just fine if I make the dates exactly a month apart. But I will get a fix out in the next few days to a week, I hope.

Nicolás says:

Thanks!! Yeah well, in my case I was setting it as todays date and first withdrawal April 1st. Interest at 10% monthly withdrawals and compounding during 18 months. $10,000 savings in hand and 300 withdrawals. I hope you can fix it :). Oh and it didn’t calculate the amount of months asked to. It just did 2. Best regards

Karl says:

Nicolas, I released a fix this morning, so all should be good now.

If you don’t mind, please confirm. If there are still problems, I will certainly work on them until they are resolved.

Thanks you very much for your help. I can now confirm it is working like a charm!!

Great! Thanks for letting me know.

## Tse says:

Hi Karl, this is amazing. Thank you!

Are there any financial withdrawal calculators (or perhaps you will develop one) that will allow for annual Cost of Living Adjustments (eg, 2 to 4%)?

Thanks again for this fantastic public service!

## Karl says:

Thank you for your nice words!

Yes, there is.

Please see this investment calculator. Set the "cash flow type" to "income" for what you want.

## Mary says:

This is good but what about inflation?

## Karl says:

Thank you.

You are right. Please use this (newer) Investment Calculator and set the cash flow type to "income."

You’ll see under optional settings that you can enter an "Annual Inflation Rate."
