Bankroll Guidelines
  • Never risk more than 0.7% of your bankroll in a single night
  • Maximum single contest entry: $20.00
  • At $1,000, you can comfortably support this nightly budget
  • Your budget is tight — focus on fewer, higher-confidence entries
  • Re-check sizing when your bankroll changes by 20% or more

Why Bankroll Management Matters More Than Lineups

The best lineup builder in DFS will go broke without proper bankroll management. Variance in daily fantasy is extreme, especially in GPPs where you might cash only 15-20% of entries even with a significant edge. Kelly Criterion sizing ensures your nightly spend matches your actual edge while protecting against inevitable losing streaks.

How the Kelly Criterion Works for DFS

The Kelly Criterion calculates the optimal bet size based on your edge divided by variance. In DFS, this means adjusting for contest-type-specific variance: GPPs have 4x the variance of cash games, so Kelly recommends smaller GPP allocations relative to cash game allocations for the same ROI. Most profitable players use quarter-Kelly or half-Kelly to reduce drawdowns.

Building a DFS Bankroll From Scratch

Start with cash games at minimum stakes to build a track record. Track every entry for at least 200 games before evaluating your ROI by contest type. Once you have reliable ROI estimates, use this calculator to size up. Resist the temptation to play bigger before you have the data to support it.

Frequently Asked Questions

How big of a DFS bankroll do I need?
A minimum of $500 is recommended for consistent DFS play across multiple contest types. At conservative sizing, a $500 bankroll supports roughly $10-15 per night in total action. For serious multi-entry GPP players, $2,000-5,000 provides enough runway to absorb variance.
What percentage of my bankroll should I play each night?
Conservative players should risk 3-5% of their bankroll per night. Moderate players can go up to 8-10%. Never exceed 15% in a single night regardless of confidence level. The calculator adjusts these percentages based on your ROI estimates and contest mix.
How much should I spend on GPPs vs cash games?
A common professional allocation is 60% cash games and 40% GPPs. Cash games provide steady returns while GPPs offer upside. If your GPP ROI is significantly higher than cash, shift allocation accordingly. The calculator optimizes this based on your ROI inputs.
What is risk of ruin in DFS?
Risk of ruin is the probability of losing your entire bankroll before variance works in your favor. With proper Kelly sizing and positive ROI, risk of ruin approaches zero over time. Aggressive sizing with marginal edges dramatically increases ruin probability.
Should I play the same contests every night?
Consistency in contest selection helps track your actual ROI by contest type. Playing the same structures lets you build expertise and accurate ROI estimates. However, be willing to skip nights with weak slates rather than force action.
How do I know when to move up in stakes?
Move up when your bankroll supports the higher stake at the same percentage allocation. For example, if you play $5 entries with a $500 bankroll (1% per entry), move to $10 entries when your bankroll reaches $1,000. Never move up to chase losses.
Is $100 enough to start playing DFS?
A $100 bankroll limits you to $1-3 entries per night at conservative sizing. This is enough to learn and track results but not enough for multi-entry GPP strategies. Start with cash games and head-to-heads at minimum stakes to build both skill and bankroll.
How does variance differ between GPPs and cash games?
GPPs have approximately 3-4 times the variance of cash games. A profitable GPP player might lose 15-20 nights in a row before hitting a big score. Cash game players experience smaller swings but need higher volume to generate meaningful returns.
