About this calculator
In fantasy auction drafts, budget allocation is the single biggest edge you can develop. This calculator splits your total budget into two pools: money reserved for starters and money reserved for bench depth. The strategy setting is the share of the budget aimed at starters (70% for stars and scrubs, 60% balanced, 50% value-based); the rest is the bench pool. Because every bench spot costs at least $1, the starter pool is capped at totalBudget − bench spots. The result is the average amount you can spend per starting spot: perStarter = min(totalBudget × strategy, totalBudget − (rosterSpots − starterSpots)) / starterSpots. The bench average is totalBudget × (1 − strategy) / (rosterSpots − starterSpots). These averages are guardrails: you will pay more than the starter average for your top player and less for value picks.
How to use
Assume a $200 total budget, 15 roster spots, 9 starter spots, and the stars-and-scrubs strategy (0.70). Starter pool = 200 × 0.70 = $140. Bench pool = 200 × 0.30 = $60. Bench spots = 15 − 9 = 6. Per starter = 140 / 9 ≈ $15.56; per bench player = 60 / 6 = $10. With the default inputs ($200, 16 spots, 9 starters, balanced 0.60) the starter average is $120 / 9 = $13.33. In practice you will exceed the average on star players and dip below on value picks.
Frequently asked questions
What is the best draft strategy value to use for a stars-and-scrubs auction approach?
A stars-and-scrubs plan puts the largest share of the budget into starters; this calculator offers 0.70 for it, 0.60 for a balanced build and 0.50 for value-based drafting. Many stars-and-scrubs players go further, spending 85–90% on starters and filling the bench with $1 bids, which you can model by reading the starter average as a floor. This approach works best in leagues where elite production is hard to replicate on the waiver wire, but it carries risk if your expensive studs get injured.
How does league size affect how I should allocate my auction budget?
Larger leagues mean player values are more inflated at the top because more managers are competing for the same scarce talent pool, driving up auction prices for elite players. In a 14-team league versus a 10-team league, the same dollar amount buys meaningfully less starter quality, so you may want to raise your strategy value to ensure your starter pool is large enough. League size is not directly in the formula but it informs the realistic cost of players at auction and should guide where you set your strategy parameter. Researching Average Auction Values (AAVs) for your specific league size before the draft is strongly recommended.
Why should I calculate per-spot budget allocation before a fantasy auction draft?
Without a budget plan, it is easy to blow 60% of your money on the first three players nominated and then scramble to fill your roster with $1 bids. Pre-calculating per-spot allocations gives you a real-time anchor during the auction so you can quickly judge whether a current bid exceeds your plan. It also helps you identify value opportunities — if a player you rated at $30 is going for $20, your plan tells you instantly that you have room to bid aggressively. Professional auction drafters treat their budget plan as a living document they adjust round by round as the draft unfolds.
