Compute Founder Vesting Acceleration Payout on Change of Control
A precise breakdown of how many founder shares vest at a change-of-control event under the grant's acceleration terms, so the founder knows their stake before signing.
Compute New-Hire Equity Grant by Hire Number
A pure function that returns the equity-grant percentage for the Nth early hire by interpolating between configurable anchor grants (default 1.5% for hire #1, 0.25% for hire #20), per the YC early-hire equity rule of thumb.
Compute NRR, GRR, net churn, and the Rule of 40
You get Gross Dollar Renewal Rate, Net Dollar Retention Rate, net churn rate, and the Rule-of-40 sum, each computed from your supplied revenue figures with the standard SaaS definitions.
Compute prorated outside-activity day allowance
A function that takes an appointment fraction, the per-quarter full-time day limit, the off-duty multiplier, and the assumed workday hours, and returns the allowed outside-activity days per quarter, per year, and the equivalent hour budget.
Compute Raise Amount and Implied Valuation from Inflection Point
A single headline raise number, the implied post-money valuation range, the investor ownership range it implies, and a flag for whether the ask sits inside the track-record-appropriate band, so the founder can answer 'how much are you raising?' with one defensible figure.
Compute required ownership and present value from a target exit
A function that, from a projected exit value, holding period, and target return, computes the required present ownership fraction and the implied present value of the position.
Compute self-employment tax and quarterly estimated payments for a supplied tax year
You get your self-employment tax for the supplied net earnings plus the four equal quarterly estimated payments, computed for the tax-year rates and thresholds you provide.
Compute the bill under a linear, 2-part, or 3-part tariff
I give a usage volume and a tariff schedule and get the exact amount owed, with the right block selected and overage applied only above included units.
Compute the break-even sales change for a price change
You get the minimum percent (and unit) sales-volume change at which a proposed price change leaves total profit contribution unchanged.
Compute the dilution impact of a pre-money option pool top-up
A function that computes the effective (pool-adjusted) price per share and the share of dilution borne by existing holders when a new option pool is created on a pre-money basis.
Compute the Van Westendorp acceptable price range
I enter each respondent's four price answers and get back the deterministic Van Westendorp points (PMC, PME, OPP, IPP) on the observed price grid, so I have a defensible acceptable-price band.
Compute Viral Coefficient and Loop-Driven User Growth
A founder learns their viral K-factor and the cumulative users a seed cohort generates across viral cycles, so they can judge whether the product can grow on the viral engine alone.
