The Kelly Calculator

What it does

1. You enter your total bankroll — the amount you want to put to work on today's Alien tips. Nothing is pre-filled; you stay in control.
2. Kelly sizes each tip from its model edge and the market odds. Tips with more edge get a larger share; thin-edge tips get less.
3. Your whole bankroll is split across the day's tips. Weights always add up to 100% — no leftover cash sitting idle, no guessing stake sizes.
4. You lock the daily split in one tap. That book feeds Your Kelly P&L — separate from My Punting, so you can compare a disciplined Kelly day against any stakes you log yourself.

Why punters use it

• →Removes stake guesswork. No more flat $20s or gut-feel doubles. Every tip has a clear each-way unit and % of bankroll.
• →Puts more on the better spots. Edge drives the split, so your strongest selections carry more of the day's money.
• →Keeps a clean second ledger. Lock the split and track Kelly P&L on its own — strike, ROI and outlay — without mixing it into casual or manual bets.
• →Matches the Mothership model. The club deploys a fixed daily bankroll the same way. You can run your own balance beside the public Mothership Kelly P&L.
• →Built for racing days, not textbooks. One screen: total bankroll, tip-by-tip breakdown, lock. No fraction pickers, no jargon walls.

How it works in the app

The Kelly Split is included with Spaceship Commander (and the free Commander trial). Elite members still get daily tips; full bankroll sizing and Kelly P&L sit on Commander.
