Make the most of your nest egg.

Your income, your taxes, your investment accounts, and your retirement accounts all draw on the same nest egg — and most people manage them in separate silos. We show you how to run them the way a family office would: coordinated, tax-first, using strategies written into the tax code itself — explained in plain English, with a free calculator to run your own numbers.

$50K$3M+
Both paths convert the same balance at 55 — the modeled difference is whether same-year deductions absorb the conversion tax
Convert with offset
No strategy — pay the tax

By keeping most of the tax invested instead of paying it, the offset path pulls ahead by$1.8Mby age 90 — balance plus all the income drawn along the way.

Illustrative model, not a projection — it isolates the tax effect and does not include the capital, fees, returns, or risk of the deduction-generating investment itself. Your numbers will differ. Not tax advice.
Adjust assumptions8% return · $5,500/mo from 65 to 90 · 65% laddered offset · 2026 MFJ brackets + 5% state

Same base case as the full calculator: a laddered conversion starting at 55 with deductions offsetting 65% of each slice's tax, after-tax withdrawals from 65 to 90, married filing jointly, compared on total value. Open the full calculator to change ages, the offset share, or see all four paths.

Why it matters

The less you lose to tax, the more your nest egg compounds

A Roth conversion is taxed up front. The smaller you can keep that tax bill, the more of your savings stays invested and growing — here's the long-run difference on a $500,000 conversion.

What it takes to catch up after paying the tax up front

Keeping the conversion tax low is the whole game. There are legitimate, code-based ways high earners do this — see the strategies or the advanced guide.

The payoff, ranked

Same $500,000. Four strategies. One breaks away.

Run the same balance, the same returns, and the same retirement income four different ways. Three land in a tight band — then one pulls ahead by more than $1.4 million by your plan-end age, even with deductions covering only 65% of the conversion tax.

The other three paths
Convert over time (laddered)$1.69M
Leave it in your IRA / 401(k)$1.62M
Convert & pay the tax$1.28M
Within roughly $400K of each other.
Convert with a 65% offset
$3.08M
about $1.4M+ ahead of the other three

Illustrative example — your numbers will differ, and the offset path shows the tax effect only: the capital, fees, returns, and risk of the deduction-generating investment sit outside this model. Run yours in the calculator →

Why you can trust this

Built from primary sources, written by a family-office practitioner

The Nest Planner is written by Casmir Mason — CFO of a private family office and CEO of North Pine Capital — who has run these strategies with real capital. Every tax claim is built from the Internal Revenue Code, Treasury regulations, and official IRS guidance, and cited so you can verify it yourself.

Sourced

Tax claims trace to the IRC, Treasury regs, or IRS publications — not opinion.

Honest about risk

Every strategy discloses its requirements, limits, and the investment risk involved.

Educational, not advice

This is a starting point for your own research and a conversation with your CPA — not a sales pitch.
