Illustrative worked example: STUD is a registered trade name of TELEVORT INC, a Delaware corporation with a sole founder, at pre-seed with no committed round, so the cap table below is invented for the example and every figure here is illustrative, anchored on the illustrative $1,000,000 raise target on file. Assuming 10,000,000 fully diluted pre-round shares and a $0.50 price per share: pre-money is 10,000,000 x 0.50 = $5,000,000 (price-led, derived as shares times price); post-money is 5,000,000 + 1,000,000 = $6,000,000; new shares are 1,000,000 / 0.50 = 2,000,000 (a whole number, no share rounding needed); post-round shares are 12,000,000; the new investor holds 2,000,000 / 12,000,000 = 16.67 percent and existing holders keep 10,000,000 / 12,000,000 = 83.33 percent at the default 2 decimal places. Arithmetic recomputed against the tasks.py _premoney_reference oracle, 2026-10-12; every output field matches the oracle exactly. Option-pool top-ups are out of scope for this play.

Scope of the check
What's verified: STUD verifies the ARITHMETIC only. This calculator is price-led: you supply the price per share set in the round and your pre-round fully diluted share count, and the pre-money valuation is derived as shares times price (it does not ask you for a pre-money valuation directly). Post-money is pre-money plus the amount raised; new shares are the amount raised divided by the price per share, rounded to the nearest whole share (exact half-shares round to the nearest even count); the new-investor and existing-holder percentages are taken over the post-round share count. The percentages are reported to at most 4 decimal places, whatever precision you request in the advanced options. It does NOT model an option-pool top-up or the pre-round pool expansion that dilutes founders, which is a separate option-pool calculation. Whether your share count, price, and raise figures are right is your judgment, not graded.
