Calculate NUA Tax Savings Before Your Next Rollover
Our net unrealized appreciation calculator compares NUA strategy vs. IRA rollover tax costs instantly — so you know exactly which route saves you more.
By utilizing the NUA strategy, you potentially save on long-term taxes compared to a standard traditional IRA rollover layout.
Frequently Asked Questions
Stop overpaying on 401(k) distributions. Our net unrealized appreciation calculator shows your real tax savings in seconds — and sharpens your retirement exit plan.
A: A net unrealized appreciation (NUA) calculator estimates your potential tax savings when you distribute company stock from a 401(k) instead of rolling it into a traditional IRA. It compares two tax outcomes side by side: the NUA strategy cost vs. the standard IRA rollover tax cost — so you can see which path keeps more money in your pocket.
A: The formula is straightforward:
NUA = Current Market Value − Cost Basis
- Your cost basis is what your employer originally paid for the stock inside your plan.
- Your NUA amount gets taxed at the long-term capital gains rate (typically 15–20%) when you sell — not your ordinary income rate.
- Only the cost basis portion is taxed as ordinary income at distribution.
Enter these three numbers into the calculator and it handles the rest.
A: It depends on the spread between your ordinary income tax rate and your capital gains rate. The wider the gap, the more NUA saves you. In the example above — 32% ordinary rate vs. 15% capital gains rate — the NUA strategy saves $34,000 over a standard IRA rollover. If your ordinary rate is close to your capital gains rate, the advantage shrinks significantly.
A: NUA lets you split your 401(k) company stock into two tax buckets:
- Cost basis → taxed as ordinary income in the year of distribution
- Appreciation (NUA) → taxed at the lower long-term capital gains rate when you eventually sell
This effectively lowers the blended tax rate on your total distribution — often by 10–17 percentage points compared to a full IRA rollover, where everything is taxed as ordinary income on withdrawal.
A: Four fields drive the calculation:
- Cost Basis ($) — your employer's original purchase price for the stock
- Current Market Value ($) — today's fair market value of the stock
- Ordinary Income Tax Rate (%) — your current federal bracket
- Capital Gains Tax Rate (%) — typically 0%, 15%, or 20% depending on income
The calculator outputs your NUA amount, NUA strategy tax cost, IRA rollover tax cost, and estimated tax savings side by side.
A: The NUA strategy makes the most sense when:
- Your company stock has appreciated significantly above its cost basis
- You're in a high ordinary income tax bracket (22%+)
- You plan to sell the stock after distribution rather than hold it long-term inside an IRA
- You're taking a lump-sum distribution — NUA only applies to qualifying lump-sum events (separation from service, reaching 59½, death, or disability)
If you're in a low tax bracket or the stock hasn't appreciated much, a standard IRA rollover likely wins.
A: No. Net unrealized appreciation rules apply specifically to employer-sponsored qualified plans — primarily 401(k), 403(b), and pension plans that hold company stock. IRAs, Roth accounts, and non-qualified plans are not eligible. The stock must also be distributed as actual shares (an in-kind distribution), not liquidated first.
A: Three worth knowing:
- Concentration risk — you're holding a large position in a single company stock outside a tax-sheltered account.
- Immediate tax hit — the cost basis is taxed as ordinary income in the year of distribution, creating a lump-sum tax liability.
- State taxes — some states do not recognize the federal NUA tax treatment and tax the full distribution as ordinary income.
Run your numbers with the calculator first, then confirm the state-level impact with a tax advisor.
