Is a GRAT Worth the Setup Fee? A 6-Question Break-Even Checklist for a $3 Million Stock Position (October 2026)
On October 1, NerdWallet ran two mortgage headlines within hours of each other: "Mortgage Rates Today, Thursday, October 1: Rates Rise Sharply" and "Weekly Mortgage Rates Find a New Normal Above 7%." The same week, NerdWallet asked "Is the New IHG Premium Card Worth Its $350 Fee?" and published a writer's "one rule" for Prime Day shopping.
None of these five articles is about estate planning. They all teach the same habit, though: before you pay an entry price, find the break-even and ask whether you'd do it anyway.
Here is that habit applied to a question people keep asking me: is a GRAT worth the fee?
The Scenario: Dana, $3 Million of One Stock, and a $7,500 Quote
Dana is 61, single, with an $11 million estate. $3,000,000 of it sits in one stock position after a big run-up, with a $600,000 cost basis. Her advisor says "GRAT." The drafting, valuation, and gift-tax return quote is $7,500.
Assumptions, all labeled as examples:
- The $7,500 fee is hypothetical, so get your own quote.
- The hurdle rate is 4.8%. The IRS publishes the actual Section 7520 rate monthly, and you use the rate for the month you fund.
- Federal estate tax is 40% above the exemption.
- Heirs who sell pay 23.8% (20% capital gains plus 3.8% net investment income tax).
- Dana has no state estate tax.
Your numbers will differ. The structure of the questions won't.
What Five Unrelated Articles Teach About Estate Decisions
- The card-fee test. NerdWallet's IHG piece makes the card sensible if you're already planning IHG stays. A $350 fee is neither good nor bad on its own. It's good if you'll use the benefit enough to clear it. A GRAT's fee works the same way.
- The Prime Day rule. The writer only restocks "stuff I'd buy anyway at a discount." Gifting works the same way. A big exemption is not a sale you have to shop. Make the transfers you'd want to make anyway, and optimize the timing and the asset you give.
- The rate regime. NerdWallet's "new normal above 7%" framing suggests it's OK to reevaluate plans when borrowing costs climb. The Section 7520 rate isn't a mortgage rate, but both follow Treasury yields in the same direction. Rising rates raise the GRAT hurdle and change what a down-payment gift does for your kid.
- The market regime. Mr. Money Mustache's September 25 post, "Will the AI Bubble Destroy our Retirement?", opens with how the market keeps surprising us in both directions. A GRAT's outcome depends on which way it surprises you during the term.
Question 1: Will Your Estate Actually Be Taxable?
If the answer is no, nothing below matters for federal purposes, and you've saved your fee.
Under current law, the 2026 federal exemption is $15 million per person, or $30 million for a married couple who file for portability. It is indexed after 2026, and Congress can change it. Many states tax much lower estates, so check yours separately.
Dana's $11 million is under $15 million today. But estates grow and exemptions grow slower. Assume the exemption is indexed at 2.5% a year, so 10 years out it's about $19.2 million. Here is her projected estate before any spending or gifting:
| Portfolio growth/yr | Estate in 10 years | Over the exemption | Federal tax at 40% |
|---|---|---|---|
| 4% | $16.3M | Under | $0 |
| 6% | $19.7M | $0.5M | ~$0.2M |
| 8% | $23.7M | $4.5M | ~$1.8M |
The same estate faces $0 or about $1.8 million depending on growth you can't know yet. If you're at the 4% end, the GRAT is a $7,500 donation to your law firm. At the 8% end, it's one of the cheapest insurance policies you'll buy. You can model your own range at Voritanel.
Question 2: How Much Does the Stock Need to Beat the Hurdle?
A GRAT hands the assets back to you as annuity payments, sized so the gift is roughly zero. Whatever grows faster than the hurdle rate is left over for your heirs.
Dana funds a 2-year GRAT with $3,000,000. At a 4.8% hurdle, the annuity factor is 1/1.048 + 1/(1.048)² = 1.8647, so each annual payment is $1,608,844.
At 10% stock growth:
- Year 1: $3,300,000 minus $1,608,844 leaves $1,691,156.
- Year 2: $1,860,272 minus $1,608,844 leaves $251,428 for her heirs.
Here is the full range:
| Stock growth/yr | Remainder to heirs | Tax saved at 40% | Net of fee, heirs hold | Net of fee, heirs sell |
|---|---|---|---|---|
| 4% | $0 | $0 | -$7,500 | -$7,500 |
| 8% | $152,804 | $61,122 | $53,622 | $23,490 |
| 10% | $251,428 | $100,571 | $93,071 | $43,123 |
| 15% | $508,485 | $203,394 | $195,894 | $93,177 |
| 20% | $780,543 | $312,217 | $304,717 | $144,753 |
Below the hurdle, the stock comes back to Dana and she's out the fee. That is a real feature of GRATs. They're a mostly one-way bet on the downside, and the 4% row only costs you the fee.
This is the kind of analysis Voritanel runs for you, so you don't have to build the spreadsheet yourself.
Question 3: What Does It Do to Your Step-Up in Basis?
Assets that stay in your estate get a new tax basis at death. Assets that pass through a GRAT remainder generally keep your old, low basis. That's the hidden cost in the last column of the table.
Dana's basis is 20% of today's price. By the end of the 2-year GRAT at 10% growth, about 83% of the remainder is untaxed gain. If her heirs sell, they owe about $49,900 on a $251,428 remainder. That's half of the estate tax saved.
If the heirs hold the stock long term, or never sell it, that drag goes away. So the GRAT's value depends on what your heirs will do with the stock. A GRAT stacked on a plan to hold forever looks very different from one stacked on a plan to diversify next spring.
For more on this trade-off, see when a GRAT beats an IDGT.
Question 4: What Growth Rate Clears the Fee?
This is the IHG card question: how much do I have to use it to justify $350? Here the answer is a growth rate.
Solving for the stock growth at which Dana's remainder covers her $7,500 fee gives:
- About 5.2% a year if heirs hold and the estate is taxed at 40%. That's only 0.4 points above the hurdle.
- About 5.6% a year if heirs sell right away and pay 23.8% on the gains.
- Never, if her estate stays under the exemption.
Dana's stock grew far faster than 5.6% over the past few years, but that is the past and not a forecast. If you have a view on forward growth, compare it with those thresholds.
Question 5: Would You Do This Anyway? (The Prime Day Rule, Applied to Down Payments)
Say Dana's daughter is buying a home, and Dana wants to help with a $100,000 down payment. NerdWallet's "new normal above 7%" headline makes that gift worth more than it was at 5%.
Assuming a 7.0% 30-year loan:
- An extra $100,000 down cuts the payment by about $665 a month, or about $7,980 a year.
- It saves about $139,500 in interest over 30 years.
- That is a guaranteed 7.0% for your daughter, above the 4.8% hurdle a GRAT has to clear. That's a different kind of return than the GRAT's, but it is real.
On the gift-tax side:
- $19,000 is the 2026 annual exclusion per recipient.
- The other $81,000 goes on a gift-tax return (Form 709) and uses about 0.54% of Dana's $15 million exemption.
- No tax is due.
This is the Prime Day logic: if the gift is something Dana would do anyway, the only decisions left are timing and asset. If she gives appreciated stock instead of cash, she hands over a low basis, so the cash-versus-stock question is its own break-even. See gifting a $100,000 down payment with mortgage rates above 7%.
Question 6: What Happens in the Bad Case?
Run three scenarios on the GRAT before you commit:
- The AI-style crash. If Dana's stock drops 30% in year one, the trust can't pay the annuity from growth, so it pays out what it has. She gets the stock back, minus the fee. Nothing worse happens, but the stock is also worth less in her estate. A rolling series of short GRATs can capture the rebound that a single crash would otherwise waste. Mr. Money Mustache's September 25 piece is a good read for the retirement side of that fear. On the estate side, see the AI-bubble checklist for a $20M estate.
- Rates keep climbing. At a 5.3% hurdle instead of 4.8%, Dana's annuity rises to $1,620,275 and the 10%-growth remainder falls from $251,428 to $227,422. That is $24,006 less to her heirs and about $9,600 less estate tax saved. To see how that scales on bigger estates, see what mortgage rates above 7% do to a $10M GRAT versus IDGT.
- You die during the term. The assets are pulled back into your estate. You lose the fee and get no tax benefit. You do keep the step-up on those assets.
Three Paths for the Same $3 Million
| Hold for step-up | 2-year GRAT | Direct gift | |
|---|---|---|---|
| Exemption used | None | Near zero | $3,000,000 (20% of $15M) |
| Growth removed from estate | None | Excess over 4.8% for 2 years ($251,428 at 10%) | All future growth |
| Basis for heirs | Steps up at death | Carryover | Carryover |
| Embedded gain at risk | $0 | About $210K of the remainder | $2.4M today (up to $571,200 at 23.8%) |
| Cash cost | $0 | $7,500 assumed | Gift-tax return cost |
| Worst case | Estate tax if you're taxable | Fee lost | Gave up the step-up for nothing |
Dana's direct-gift math at 10% growth for 10 years:
- The stock grows to about $7.78M.
- Estate tax saved on the growth is about $1.91M at 40%, if that growth would have been taxed.
- Step-up lost on about $7.18M of gain is worth up to $1.71M if heirs sell.
- Net advantage is about $203,000.
The gift only saves estate tax on the part of your estate above the exemption, but it gives up the step-up on all of the gain. If part of the growth would have fallen under the exemption anyway, that $203,000 shrinks fast or flips negative. That is the same asymmetry as Question 1.
The One-Page Checklist
- Projected estate vs. exemption. Test your growth range against both federal and state thresholds. Include portability if you're married.
- Growth vs. the 7520 hurdle. Look up the current month's rate and run the GRAT table at your realistic growth rates, including a bad one.
- Basis. Find your embedded gain and decide whether your heirs would sell.
- Fee break-even. Work out the growth rate that clears your actual quote, like Dana's 5.2% to 5.6%.
- Would you do it anyway? Gifts you'd make regardless are easy. Gifts made only because a window feels open deserve more skepticism.
- Bad cases. Model a crash, a rate rise, and death during the term.
Reasonable people end up in different places. A taxable $30 million estate and an untaxed $11 million estate should reach different answers, and so should a low-basis stock and a high-basis one.
Run the Numbers for Your Situation
Dana's example shows how much swings on a few inputs: her growth rate, her state, her basis, and how long the stock sits. Replace those with your own and the table looks different, and sometimes the answer is "do nothing."
You can model your own position at Voritanel: your estate, your basis, your state, and the current hurdle rate. You'll see the break-even before you pay a fee, which is the same thing the NerdWallet articles suggest doing before you sign up for a $350 card.
