Cash Flow Strategy: Tax-Free Strategy

IFR Module 231 — Taxable vs. Tax-Deferred vs. Tax-Free

The core concept: Three accounts, same contribution, same gross return — but dramatically different outcomes because of HOW and WHEN taxes are applied. This calculator reveals the true cost of taxes on wealth accumulation and retirement income.

Accumulation Phase — Growth Comparison

All three strategies with the same gross return, but different tax treatments during accumulation.

Distribution Phase — Net After-Tax Annual Income

When you withdraw, taxes hit again. This chart shows the net spendable income from each strategy.

The Tax Impact Summary

Key Takeaway

  • Taxable accounts suffer double taxation — taxed on growth every year AND on gains at withdrawal. The annual tax drag prevents full compounding.
  • Tax-deferred accounts (401k/IRA) defer taxes but pay the full bill at withdrawal. Every dollar withdrawn is taxed as ordinary income. You're a "tax partner" with the government.
  • Tax-free accounts (Roth/LIRP) use after-tax dollars but never face taxes on growth or withdrawals. The longer the time horizon, the more dramatic the advantage.
  • The LIRP advantage over Roth: no contribution limits, no income phase-outs, no required minimum distributions, plus death benefit and living benefits.
