About this calculator
Auction drafts require a completely different prep approach than snake drafts: instead of ranking players, you need a dollar budget per position group before you ever open the auction room, or you'll blow 40% of your cap on the first two running backs and be stuck bidding $1 on everyone else. This calculator splits your total budget (standard is $200 per team) across starting positions using percentage targets you can adjust for your league's scoring format, and reserves a bench allocation so you don't spend your entire cap on starters and end up with only $1 bench pieces. Standard guidance in most redraft leagues allocates roughly 60-70% of budget to your top handful of starters (usually RB/WR-heavy), leaving the remainder split between mid-tier starters and bench depth. Adjust the position percentages based on your league's scoring — heavier PPR formats generally shift more budget toward receivers, while standard scoring skews more toward workhorse running backs.

FAQ
Why do RBs usually get the biggest budget share?
Running back is typically the shallowest position with the steepest talent drop-off after the top tier, and workhorse backs with guaranteed touch share are historically the hardest wins to replace late or on waivers, which is why standard auction strategy front-loads RB spending relative to its roster share.
Should I change these percentages for a PPR or superflex league?
Yes — heavier PPR scoring closes some of the RB/WR value gap and often shifts a few percentage points of budget toward WR, while superflex leagues (that start two QBs) should meaningfully increase QB allocation, sometimes to 20%+ of total budget, since a second startable QB becomes a scarce, highly valuable roster spot.
What's the risk of not setting a budget before the draft?
Auction drafts move fast and it's easy to get anchored on winning a specific star player, overspending on the first few nominations, and then having almost nothing left for the remaining 12-15 roster spots. A pre-set budget by position is the single easiest way to avoid ending a draft with a strong top-3 and an unusable bench.
