Net final value at year 3 sale — optimized plan
$39,214
After-tax dollars at end of year 3, net of all federal + state taxes through the sale.
This year: exercise 10,000 shares.
= gross gain at sale − federal + state LTCG − AMT premium above baseline regular tax (time-valued)
AMT premium for exercising: $0 (on top of $228,434 regular tax across the horizon)
Lump-sum stays under your AMT crossover — no schedule optimization needed.
Federal AMT crossover this year: 12,204 shares ($57,238 bargain element). Above that, each additional share this year adds federal AMT.

Net final value by year
Running tally: NTV from shares exercised through year y, minus AMT premium paid through year y. The last year matches the plan's headline NTV. Hover a year for plan totals.
Optimized exercise schedule
You pay the higher of Regular tax and Tentative AMT per jurisdiction, then subtract Credit recovered. The result is Net tax. Hover any number for the bracket-by-bracket breakdown.

Estimates only. Excludes disqualifying dispositions, NSOs, multi-state moves, and AMT preferences other than ISO bargain elements. Long-term capital gains tax assumes a qualifying disposition (ISO held ≥1 yr from exercise and ≥2 yr from grant); state LTCG follows ordinary brackets except where the state grants preferential treatment (HI, ND, SC, WI, AR, NM) or has a dedicated LTCG-only tax (WA). Assumes you are within the $100K ISO limit (any portion of an annual ISO grant whose FMV at grant exceeds $100K is treated as NSO from the start, §422(d)). State AMT figures are 2025 (next-year values published in late 2026). Not financial advice.
QSBS note. If your shares qualify (typically pre-IPO C-corp grants held 5+ years), a federal rule lets you exclude up to $10M of gain on a future sale from federal tax. That single rule shifts exercise-timing math more than AMT does. (This is §1202 “qualified small-business stock”.) Modeled in beta, not here.
You optimized one grant in isolation. The beta optimizes ISOs alongside your RSUs, NSOs, and stock in one plan.

Relativity Space Inc. is an American aerospace manufacturing company headquartered in Long Beach, California. Relativity Space is developing launch vehicles, rocket engines, and manufacturing technologies for commercial orbital launch services. As of March 2025, Relativity has announced plans to launch its in-development launch vehicle Terran R for the first time in late 2026.

Tim Ellis and Jordan Noone founded the company in 2015 to build rockets with 3D-printed engines and structures, manufactured on proprietary Stargate metal printers at the Long Beach, California headquarters. Terran 1 flew once in March 2023 and failed to reach orbit after an upper-stage anomaly, prompting a pivot to the larger, partially reusable Terran R powered by 13 Aeon R engines. Eric Schmidt acquired a controlling stake and replaced Ellis as CEO on March 10, 2025, after the firm struggled to close new funding. Terran R targets a first flight no earlier than 2026 from Launch Complex 16 at Cape Canaveral, against a reported $2.9 billion order backlog.

The calculator works at any Relativity Space valuation: enter your strike, the current 409A FMV, an expected IPO price, or anywhere in between. AMT is triggered on the bargain element (FMV minus strike) when you exercise; the calculator models federal AMT, state AMT, and the multi-year credit-recovery path.
Example: at Relativity Space's last reported price of $9.69, exercising 5,000 ISOs with a $2.91 strike creates a $33,900 bargain element. Above the 2026 federal AMT exemption ($88,100 single, $137,000 married joint), the 28% AMT rate adds roughly $9,492 on top of regular tax before any state AMT (CA, CO, CT, MN). The credit recovers in later years when your regular tax exceeds AMT. The calculator above runs your exact figures.

Relativity Space equity questions
- How much alternative minimum tax (AMT) will I owe exercising Relativity Space ISOs?
- Exercising incentive stock options (ISOs) does not create regular income tax, but the bargain element (the fair market value at exercise minus your strike price) counts toward the alternative minimum tax (AMT). The amount depends on the bargain element, your other income, your filing status, and your state. The calculator above models federal and state AMT, the AMT crossover point, and how the credit recovers in later years for your exact Relativity Space figures.
- Does Relativity Space grant ISOs, NSOs, or RSUs?
- Equity compensation at Relativity Space typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are Relativity Space shares eligible for QSBS?
- They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Relativity Space shares qualify turns on when you acquired them and the company's asset size at that time.
