Working MVP
This first calculator compares the estimated cost of buying a target card directly against the expected spend of chasing it through packs. All prices and pull rates here are local MVP estimates, not official Pokemon data.
Current assumption set: Greninja ex in Twilight Masquerade, pack price $4.49, pull probability 0.6% per pack.

Open 10, then buy if missed
$290
Spend $44.90 on packs first, with a 94% miss chance still pushing you to the single.
Best move: buy the single
Buy the single. Chasing this card is meaningfully more expensive than buying it outright.
Your expected chase cost is about 2.9x the estimated single price, the hybrid path is still about 1.1x the single, and the break-even point is only about 57.9 packs.
Formula check: expected packs = 1 / p. Expected chase cost = expected packs × pack price. Chance after N packs = 1 - (1 - p)^N.
Reality check
After 10 packs, you still have a high chance of missing this card.
