Everything, in one lab

The tools grinders keep rebuilding in spreadsheets

Except here they actually talk to each other — and the math is done right.

ROI & variance engine

Real EV and standard deviation per tournament — from field size, structure and buy-in. No more gut feel about which fields are worth it.

Bankroll shots

The exact bankroll to take each shot, with Climb and Stability risk models — so you always know the biggest game you can afford.

Session grid planner

Auto-build your session under a table-load and variance budget, instead of fighting a spreadsheet at 6pm before the grind.

Satellites

Your real probability of turning a small buy-in into a seat through a sat chain — and whether that path beats buying in direct.

Staking & markup

Fair markup from your own ROI, keep/sell splits, and your EV after selling a piece of your action. Backers included.

Grind mode

A live timeline of your session — every registration time, every room, colour-coded. Follow it while you play instead of scrambling.

From results to a plan

Three steps, then just play

Add your tournaments

Import your grid or a full Excel, or add your rooms by hand. Buy-in, structure, field — Bankroll Lab handles the rest.

Calculate

One click computes ROI, variance and your bankroll shots across the whole field — with your own risk model and markup tiers.

Play your grid

Generate the optimal session under your table cap, then follow it live in Grind mode. History tracks every unlock as your roll grows.

Your data stays yours

Privacy-first, by design

Your bankroll is nobody's business but yours. We built it that way on purpose.

No-log

We don't track how or when you play. No behavioural logging, no selling data, no ads. Your grind stays private.

zero tracking

Backups auto-expire

Cloud backups are kept for one week, then wiped. Nothing lingers on our side — and you can export a full copy anytime.

7-day retention

Payments via Stripe

Card and billing details are handled entirely by Stripe. Your payment information never touches our servers.

Stripe-secured

Built on real tournament math.
Not a spreadsheet with vibes.

Every number comes from a proper model of expected value, variance and bankroll risk — not a fudge factor or a gut read. The rigor you'd want if you built it yourself, without the weekend of spreadsheet surgery.
