IRA Savings Comparison Calculator: Tax Deferred Growth Vs Taxable Growth

Calculator Preferences
IRA Savings Comparison Calculator Sign
IRA Savings Comparison Calculator

This calculator will forecast the annual growth and future value of a traditional Individual Retirement Account, and then compare those tax-deferred results to an investment for which the returns are taxable in the year they are earned. Results include a year-by-year comparison chart and a button for creating a printer friendly report.

Balance at retirement:

The left-hand column is the estimated future value of your IRA, which has grown at the full expected return on investment (tax-deferred).

The right-hand column is the estimated future value of a non-IRA investment, which has grown by the after-tax return on investment (ROI x (1 - tax rate)).

Taxes dueTaxes due if drawnTaxes due if withdrawnTaxes due if withdrawn at retirement:

Taxes due if withdrawn at retirement:

The left-hand column is the amount of taxes that would be due on your IRA if you withdrew the funds at retirement, since tax on both contributions and earnings are deferred until the funds are withdrawn.

The right-hand column is zero, since you would have already paid taxes on the contributions and earnings.

After-tax withdrawal at retirement:

The left-hand column is the estimated after-tax value of your IRA.

The right-hand column is the estimated after-tax value of a non-IRA investment.

Help and Tools

Help and Tools:

This section, which you can Unstick or Hide in the Calculator Preferences (just above the top of the calculator), contains the following tabs (content too long to fit within bordered frame can be scrolled up and down):

About: Click this tab for an introduction to the calculator.

Instructions: Click this tab for step-by-step instructions for using the calculator.

Terms: Click this tab for a list of the descriptions that are located within each popup help button (info icons).

PCalc: Click this tab for a handy "pocket" calculator you can use when you need to calculate an entry needed for the calculator.

Data: Click this tab to save a set of entries or a note in between visits. Entries and notes will be stored to your web browser's local storage (if supported by your browser of choice), meaning they can only be recalled with the same device and web browser you were using when you saved them. If you'd like to save entries and notes between devices you can do so by subscribing to the Ad-Free Member Version.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
