Why this exists
Generic dynasty rankings ignore salary cap. We don't.
Bijan at $30M is a steal in one cap league and a fireable offense in another. Cap Penalties prices every player in your league's context: cap size, scoring, roster construction, and how much of your points pie goes to defense.
Every contract, automatically priced
No manual entry. We pull every team's roster and contract from MFL, match each player to our rankings, and tag the contract as overpaid, fair, or underpaid against the recommendation.
Scoring auto-detected
We read your league's actual scoring rules. PPR rate, TE premium, pass-TD value, IDP intensity, and roster slots all pull in automatically. Position multipliers scale our recommendations to fit.
Your team in a dashboard
Pick which franchise is yours and get your cap efficiency, biggest overpays, and best bargains as the headline view. Other franchises collapse below so the page stays focused.
League-wide trade targets
See the top overpaid contracts and biggest bargains across every roster in your league. Use the bargains list as a shortlist of trade-target conversations to start this week.
IDP players valued, not ignored
Defensive players get a fair value derived from their points share within your league's defense bloc. Rookies and bench IDPs fall back to a starter-snap median so nothing shows $0.

Common questions
FAQ
Does this work with Sleeper?
Sleeper support is coming next. Today the import is MyFantasyLeague only because the cap-league audience is heaviest on MFL.
Do I need to install anything?
No. It runs in the browser. Sign in, paste your league ID, get your dashboard.
What does it cost?
Free. No ads. We do not sell or share your email. The cap calculator and every page on this site is free to use.
Does it handle IDP leagues?
Yes. We detect whether your league has IDP from your starting lineup and read your IDP scoring rules directly. Defensive players are valued by their points share within your league's defense bloc, scaled by how much of your cap allocation goes to defense.
What about non-standard scoring (TE premium, full PPR, 6-point passing TDs)?
Auto-detected from MFL's rules export. Position multipliers adjust the Cap Penalties recommendations to match your league's scoring before we render anything.
Can I delete my data?
Yes. Sign in, open Account, scroll to the danger zone, and type DELETE. Your account and every linked league disappear immediately. There is no soft delete.
