DFS Lineup Optimizer Calculator: Maximize Your Edge

Building optimal DFS lineups requires balancing salary, projections, ownership, and correlation. Our optimizer calculator helps you construct lineups that maximize expected value while fitting within salary constraints.

What Is DFS Lineup Optimization?

Lineup optimization uses mathematical algorithms to select the best combination of players within salary cap constraints. The goal: maximize projected points (cash games) or find contrarian builds with high ceilings (GPPs).

Quick Answer: Enter player projections and salaries, set your constraints (positions, salary cap, stacking rules), and the optimizer finds lineups maximizing total projected points. For GPPs, add ownership data to find leverage. Key insight: optimal isn't just highest projection—it's highest projection per dollar spent that also correlates correctly.

5. Generate Lineups: View optimal builds

Input Fields Explained

Field	Description	Example
Salary Cap	Total budget	$50,000
Positions	Required slots	QB, RB, RB, WR, WR, WR, TE, FLEX, DST
Projections	Expected points	22.5
Salary	Player cost	$7,200
Ownership	Expected % rostered	25%
Ceiling	Upside projection	32.0

Optimization Basics

The Core Problem

Maximize: Σ(Player Projections)
Subject to: Σ(Player Salaries) ≤ Salary Cap
           Roster positions filled correctly
           Custom constraints met

Value Calculation

Value = Projection / (Salary / 1000)

Example:
Player A: 18 pts at $6,000 = 3.0 pts/$1K
Player B: 22 pts at $8,500 = 2.6 pts/$1K

Player A offers more value per dollar

Cash Game Optimization

Primary Goals

Priority	Focus
1	Floor—consistent point production
2	Value—maximize points per dollar
3	Reliability—low variance players
4	Full salary usage—minimize leftover

Cash Game Settings

Setting	Recommended
Projection type	Floor/median
Ownership weight	Low/ignore
Stacking	Minimal
Salary remaining	<$200 ideally

Sample Cash Lineup Strategy

Position	Target	Example
QB	Safe floor	Kirk Cousins type
RB1	Workhorse	Heavy volume, low sharing
RB2	Value	Good matchup, salary saver
WRs	Target share	High volume receivers
TE	Safe or punt	Either pay up or minimum
FLEX	Best value	Highest floor remaining
DST	Vegas implied	Favorite at home

GPP Optimization

Primary Goals

Priority	Focus
1	Ceiling—maximum upside
2	Leverage—differentiation from field
3	Correlation—stacking for boom/bust
4	Game environment—high totals, close spreads

GPP Settings

Setting	Recommended
Projection type	Ceiling/upside
Ownership weight	High (inverse)
Stacking	Aggressive
Uniqueness	Prioritized

Leverage Calculation

Leverage = (Your Exposure) - (Field Ownership)

Player at 5% ownership, you roster in 20% of lineups:
Leverage = +15% (good differentiation)

Player at 35% ownership, you roster in 40%:
Leverage = +5% (minimal differentiation)

Stacking Strategies

QB-WR Stack

Stack Type	Correlation	Use Case
QB + WR1	+0.4 to +0.6	Core GPP stack
QB + WR1 + WR2	Higher	Tournament upside
QB + WR + opposing WR	Balanced	Game stack

Game Stack

Shootout game stack:
QB1 + WR1 + WR2 (team A)
+ WR1 (team B, bring-back)

Correlated to high-scoring game

Running Back Stacks

Stack	When to Use
RB + DST	Blowout game, defensive TD potential
RB + opposing WR	Hedge game script

Advanced Optimization Concepts

Multi-Lineup Generation

For 150-lineup GPP entry:
1. Optimize first lineup
2. Lock/exclude players at exposure limits
3. Optimize next lineup
4. Repeat with variance

Result: Diverse lineup set with controlled exposure

Exposure Management

Player Type	Max Exposure
Core plays	40-60%
Leverage plays	20-35%
Contrarian plays	5-15%
Chalk avoidance	0-5%

Correlation Matrix

Pair	Typical Correlation
QB-WR same team	+0.45

RB-WR same team	-0.05
QB-opposing QB	+0.15
WR-opposing WR	+0.20

Common Optimization Mistakes

1. Over-Optimizing to Projections

Mistake: Trusting projections as exact Problem: Projections have huge error bars Fix: Use projection ranges, not point estimates

2. Ignoring Correlation

Mistake: Max points without correlation logic Problem: Uncorrelated lineups have lower ceilings Fix: Build correlated stacks for GPPs

3. Same Build for Cash and GPP

Mistake: One strategy for all contests Problem: Cash needs floor, GPP needs ceiling Fix: Optimize separately for contest type

4. Chasing Last Week's Points

Mistake: Weighting recent performance too heavily Problem: Regression to mean Fix: Use sustainable underlying metrics

Frequently Asked Questions

How accurate are DFS projections?

Even the best projections have wide error ranges. A 20-point projection might actually range from 8 to 35 points. Use projections as guides, not gospel.

Should I use the same optimizer for cash and GPPs?

Use different settings. Cash games prioritize floor and value. GPPs prioritize ceiling and leverage. Same tool, different configurations.

How many lineups should I enter in GPPs?

Depends on field size and your edge. Single entry for small fields. 150+ lineups for large-field GPPs where lineup diversity matters.

What's more important: projections or ownership?

For cash: projections. For GPPs: both matter equally. Low-owned ceiling players are GPP gold.

Can I optimize for best ball drafts?

Yes, but adjust for scoring: ignore correlation (weekly scoring). Focus on season-long ceiling and draft position value.

Should I ever leave salary on the table?

Rarely in cash games. In GPPs, leaving $100-300 can be fine if it enables better leverage or correlation.

Pro Tips

• Cash = floor: Build for the median outcome

• GPP = ceiling + leverage: Differentiate from the field

• Correlation matters: QB-WR stacks aren't optional in GPPs

• Game environment: High totals and close spreads increase scoring

• Late swap: Update lineups with news close to lock
