A simpler retirement-tax conversation

Show the money left after taxes—not just the tax bill.

Compare two paths through your selected ending age using the same balance, tax rate, and growth assumption. The result is one plain-English, after-tax number customers can understand.

How much could be left after modeled taxes?

Estimated advantage: pay tax today$885,558

Paying the modeled tax today ends with more after-tax money in this illustration.

Stay in the traditional IRA$4,362,411IRA after estimated tax + after-tax RMD money
Pay the tax today$5,247,969Amount left after today's tax, grown tax-free
What “pay tax today” means hereThe modeled tax of $125,000 comes out of the current IRA, leaving $375,000 to grow tax-free at the selected 7% rate. Actual conversions, taxes, returns, and payment sources can differ.
Why your actual result may differThis version uses one assumed tax rate. Social Security, pensions, rental income, other income, deductions, filing status, state taxes, and Medicare premiums can change your actual tax rate—making the modeled benefit larger or smaller. It does not calculate your personal tax liability.

The simple math

Where the age-100 totals come from

Both paths are reduced to modeled after-tax money so the comparison is meaningful.

Traditional IRA after estimated age-100 tax$668,299
After-tax RMD money at age 100$3,694,112
Money left immediately after paying tax today$375,000

Estimated money at age 100

Both bars are after modeled taxes

What “stay qualified” includes

Taxes paid by strategy

See where each tax total comes from

This is the tax-only view. The after-tax benefit at the top also includes the timing of those taxes and the growth of the money left invested.

Modeled taxStay qualifiedPay tax today
Tax paid today$0$125,000
RMD + investment taxes through age 100$1,231,361$0
Estimated tax on IRA remaining at age 100$222,766$0
Total modeled taxes$1,454,127$125,000
Nominal taxes avoided by paying today$1,329,127

The nominal tax difference is not the same as the estimated net benefit. It adds taxes paid in different years without discounting them; use the age-100 after-tax comparison above for the modeled bottom line.

Follow both paths

Year-by-year after-tax comparison

Both balances below are shown after modeled taxes, so you can see which strategy is ahead at the end of every year—not just at age 100.

End-of-year comparison in whole dollars. “Stay in the IRA” includes the IRA after its modeled tax plus RMD money invested after tax.

What this helps clarify

A clearer view of the retirement-tax trade-off

Compare both strategies in after-tax dollars using the same starting balance, time horizon, tax rate, and growth assumption.

01

For people planning retirement

Turn a complicated tax question into a visual comparison you can follow from today through your selected ending age.

  • See both paths in after-tax dollars.
  • Follow the comparison year by year.
  • Adjust the assumptions to explore different scenarios.
02

For advisors and educators

Use a consistent illustration to make assumptions visible and help clients ask better, more informed questions.

  • Begin with a simple client conversation.
  • Explain where each ending balance comes from.
  • Print or save the illustration for discussion.

Designed for understanding

Transparent assumptions. Plain-English results.

This educational illustration keeps the comparison focused while making its important limitations easy to find.

Same starting point

One balance, two paths

Both strategies begin with the same retirement-account balance so the comparison starts on equal footing.

Same time horizon

Follow every year

Use the adjustable ending age to see how the modeled difference changes over a shorter or longer retirement.

After-tax finish line

Compare what may remain

The headline comparison includes modeled taxes on both paths—not an IRA balance compared with an after-tax balance.

The next conversation

Use the result to ask better questions

Explore how the assumptions change the illustration, then review taxes, income sources, and implementation choices with qualified professionals before taking action.
