A rule before any comparison: products compare when they share an objective. OptionsAhoy's objective is planning: computing what to do with your equity before you commit to anything. So this page compares planning products, whoever sells them. Companies whose main business is something else (financing an exercise, pooling shares for diversification, managing wealth at large) appear here only for their planning tools; their other products have different objectives and belong in their own comparisons. That is not a knock on those products: a plan and the products that execute it combine naturally, and you could well use both. Get the best plan you can here, then finance the exercise, buy the hedge, or hire the manager wherever the terms are best.
The table below is the planning landscape, one row per kind of planning; the last column is the OptionsAhoy answer on that row.
| Kind of planning | Who else sells it | How they charge | The OptionsAhoy answer |
|---|---|---|---|
| One decision: an exercise, a sale, a hedge, a lot order | Secfi's calculators, Carta's and ESO Fund's AMT estimators, Equity Simplified | Free (lead generation) | Eight free calculators; schedules and sell orders optimized, comparisons and pricing computed exactly, verified to the cent |
| The whole portfolio, planned jointly | Wealth managers as a service: Compound, Harness, Range | % of assets or flat annual fee | The OptionsAhoy Beta optimizes every position jointly; free during beta |
| A concentrated position's exit | Bundled with advisory relationships; StockOpter for the advisor side | Advisory fees or firm subscription | Concentration, hedge pricing, and lot order, free and self-serve |
| Planning at advisor scale, for client books | Advisor software: Grantd, Holistiplan, Gemifi | Firm subscription | Same class of math, free and verified to the cent |
One objective per comparison. Here, it is planning: the best plan makes every other product cheaper to choose.
If your problem is the plan: exercise planning tools
This is OptionsAhoy's home ground, so the comparison is direct. The table lists every notable planning tool and calculator and what each one computes; everything was last verified on August 13, 2026.
| Tool | What it computes |
|---|---|
| Secfi's planning tools | Tax calculator (the cost of an exercise, taxes included), Equity Planner and Exercise Timing Planner (compare scenarios you choose: exercise now vs. later, different exit assumptions). Estimates and comparisons, not a computed optimum |
| Carta's AMT calculator | Single-year AMT estimate (2025 & 2026) |
| ESO Fund's AMT calculator | Single-year AMT estimate |
| Equity Simplified | AMT calculator, ISO exercise planner, RSU calculator |
| myStockOptions / Kitces | Education, courses, basic tools |
| OptionsAhoy AMT + ISO Exercise Calculator (free) | Not a comparison of scenarios you pick: it searches the space of multi-year schedules and returns the optimum (which years, how many shares) for your income, state, and horizon. AMT credit recovery, all 50 states + DC, state AMT (CA, CO, CT, MN), expiration and holding-period timing, plus the single-year number. Verified to the cent |
| OptionsAhoy Beta (invite-only, free during beta) | Beyond any single calculator: plans every grant and position jointly with your whole tax situation, across years and market scenarios, into one month-by-month plan |
A single-year estimator is enough for a sanity check, and several are good at it. It is not a plan. The expensive mistakes in equity comp are multi-year mistakes: exercising everything at once when splitting across years would have saved six figures, stranding AMT credit you never recover, ignoring the state layer entirely.
The plan also prices every decision that follows it: the schedule plus the funding plan give the year-by-year cash need, and the Beta computes it inside your whole portfolio and tax situation, so the answer reflects everything you hold rather than one grant in isolation.
If you want the planning done for you: wealth managers
Planning as a service is the same objective delivered by humans, so it belongs in the comparison; the question is who does the work and what that costs. (What else these firms sell, from investment management to estate work, is outside this page's scope.)
| Firm | What it is | Cost structure |
|---|---|---|
| Compound Planning | A dedicated human advisor plus a planning platform; equity compensation, tax, estate, and investment planning in one relationship, built for founders and tech employees | See their published pricing |
| Harness | Not an advisor itself: an intake on your situation, then a match with tax and financial advisory firms that handle equity-comp cases; the firm you pick does the planning | The matched firm sets its own fees |
| Range | A team of CFPs, CPAs, and equity-comp specialists behind a software dashboard; covers equity, tax withholding and AMT questions, and estate planning, aimed at high earners | Published flat annual tiers, not a % of assets |
| OptionsAhoy's eight free calculators | The equity math an advisor would model, self-serve: ISO/AMT schedules, RSU sell-vs-hold, lot ordering, concentration, hedge pricing, QSBS. Schedules and sell orders optimized for your income, state, and goals; comparisons and pricing computed exactly | Free; independently verified |
| OptionsAhoy Beta (the main product) | The closest head-to-head in this table: every ISO, NSO, RSU vest, concentrated position, and hedge planned jointly, optimized for total after-tax wealth across multiple years and bullish, neutral, and bearish market scenarios, output as a month-by-month action plan | Free during beta; invite-only |
An advisor wins when your situation is bigger than your equity (multiple income streams, estate, charitable planning), or when you know you will not execute a plan without someone accountable for it; a good advisor's value is mostly follow-through. The free tools win when what you want is the equity answer: an advisor engaged for a full relationship is an expensive way to learn which lots to sell, and many advisors use planning software of their own to compute exactly that. When what you want is the whole portfolio optimized, not answers one question at a time, that is the Beta's job: the same head-to-head, without the fee. The combination is legitimate too: bring your computed plan to the first meeting and the conversation starts from the math.
If your problem is concentration: planning the exit
Concentration planning is deciding how much of one stock to keep, and how to unwind the rest: sell on what schedule, hedge at what cost, in what order of lots. Products that implement a diversification decision (exchange funds, direct indexing, collars) have a different objective and their own trade-offs; we compare those in dedicated deep dives on exchange funds and collars. The planning itself is what this table covers; note how thin the self-serve column is: elsewhere, concentration planning typically comes bundled with an advisory relationship or advisor software.
| Tool | What it computes |
|---|---|
| StockOpter by Grantd | Equity-award risk analysis and strategy modeling, used by advisory firms since 1999; now part of Grantd |
| Wealth managers | Concentration planning as part of the service; see the wealth-managers section above |
| Cache's Companion guides | Education from an exchange-fund seller comparing implementation options (exchange funds vs. direct indexing); guides, not a planner |
| OptionsAhoy's free trio: Stock Concentration Calculator, Protect Your Stock Calculator, RSU Lot Order Calculator | Drawdown cost of staying concentrated, collar and put pricing, and the sell order optimized for the lowest computed tax. Free; it computes, you decide |
| OptionsAhoy Beta (invite-only, free during beta) | Selling, hedging, and exit pacing are not separate decisions; they trade off across tax years. The Beta optimizes the mix jointly, taxes included, and tells you which combination wins |

If you advise clients: advisor software
Same objective, different buyer: these tools do equity planning for a book of clients, so the comparison is about practice features as much as math. If you are an equity holder, this category matters as context: when an advisor shows you an equity analysis, software like this often produced it.
| Tool | What it does for a practice |
|---|---|
| Grantd | AI-driven equity-comp platform for advisors: document reader for grant paperwork, strategy builder, client reports. It acquired StockOpter, the risk-analysis and strategy-modeling tool advisory firms have used since 1999 |
| Holistiplan | Tax-planning software (tax-return reading, scenario analysis) with equity-comp features; planning is tax-first rather than equity-first |
| Gemifi | Collects, analyzes, and tracks client equity awards and generates trading plans; built by advisors for equity-comp practices |
| OptionsAhoy (free) | The same class of math, aimed at the equity holder: no client intake, document parsing, or practice reporting, but the schedules are optimized and verified to the cent, and advisors are welcome to run client scenarios or hand a computed schedule to a client directly |
