Accessible bridge balance vs MAGI

The balance line estimates how much taxable plus penalty-free-access Roth money may be available each year, while the companion series reflects simplified MAGI.

Projected balance
Total contributions

By the end of the modeled horizon, accessible bridge assets are about $22,851.

Account balances by bucket

Track how taxable, pretax, and Roth balances shift as conversions move money across account types over time.

Taxable
Pretax
Roth

This view is useful for seeing whether the ladder is gradually replacing pretax dollars with a larger Roth pool while the taxable bridge shrinks.

Annual spending sources

See how each year of spending is funded from taxable assets, accessible Roth dollars, or an uncovered gap.

Uncovered gap

A mature ladder should show taxable assets doing more of the work early and Roth access taking over as five-year clocks clear.

Important findings
ACA guardrail is under pressure
Projected MAGI crosses the guardrail in 1 years, so the conversion target or taxable-gain exposure likely needs to come down.
The bridge appears fully funded
Taxable assets plus accessible Roth dollars cover the full spending target through age 50 in this model.
The ladder is creating future access
About $22,851 of conversions have cleared their five-year clocks by the end of the projection, creating a larger penalty-free Roth pool for later bridge years.

How it works

The calculation, without the clutter

1

WealthyNest uses reusable finance formulas for compounding, withdrawal targets, and cash-flow projections.

2

Each tool pairs those formulas with calculator-specific assumptions and a concise summary.

Where this tool is most useful

An early retiree at age 39 can use this planner to test whether taxable assets and staged Roth conversions cover spending until traditional retirement access becomes easier.

Key assumptions

What to sanity-check

  • Returns are smoothed estimates and do not reflect real-world market volatility.
  • All figures are in today's dollars unless the calculator is explicitly modeling inflation adjustments.
  • This tool is intended for planning, education, and comparison rather than certainty.

FAQ

Common questions

Are these outputs guarantees?

No. They are planning estimates based on your assumptions and should be updated as markets, taxes, and spending change.

Do these calculators replace professional advice?

No. They are a strong planning starting point, but tax, legal, and investment decisions should be reviewed with a qualified professional when appropriate.

How often should I revisit my inputs?

A good rule is to revisit assumptions after major income, spending, family, tax, or market changes and at least a few times per year.

Why do the optimistic and conservative scenarios matter?

They help you see how sensitive the result is to assumptions instead of anchoring on one exact output.
