A player value has a league attached to it
The official Draft Sharks dynasty calculator says its own values use current statistics, projections, expert rankings, and a league's unique scoring system. NFL Fantasy likewise distinguishes standard managed leagues from custom leagues whose scoring, rosters, transactions, seeding, divisions, and schedules can be changed. Those details are not decoration: a starting quarterback in a superflex lineup, a reception-heavy running back, and a deep bench stash can have very different marginal value under another format.
Write a format header before entering assets: platform, dynasty or redraft, team count, scoring, starting lineup, premium rules, and season or date. If a source offers several value tables, choose the table matching that header. The worksheet will accept any non-negative numbers, so input validity remains the user's responsibility; a mathematically balanced comparison can still be based on the wrong league model.
Create a provenance-safe trade ledger
Treat the two packages as one small dataset rather than two lists assembled from whichever numbers look convenient.
- Freeze one source and check date
Name the ranking, projection set, trade chart, or private model and record when it was checked. A player injury or depth-chart change can date a value quickly, so retain the source date with the result.
- Lock one league variant
Do not mix a one-quarterback player column with superflex quarterback values, dynasty picks with redraft rest-of-season values, or tight-end-premium entries with ordinary PPR values. The labels should make the shared format auditable.
- Pair names and numbers
Enter each player or draft pick as a separate row on the team that receives it. Use unambiguous pick labels such as year and round. Recount uneven packages so a throw-in does not disappear from the sum.
- Explain any signed adjustment
A consolidation, roster-slot, fit, or scarcity adjustment belongs outside the raw item subtotal and needs a short reason. Enter zero when the common source already accounts for the effect or when you cannot defend a separate adjustment.
Three readings of the same package
The output is strongest when each number is given a narrow job.
Adjusted total
This is the sum of entered players and picks plus the visible signed adjustment. It answers which package is larger on the chosen scale; it does not say which team has a greater championship probability.
Symmetric percentage gap
The absolute difference is divided by the larger adjusted side, so swapping Team A and Team B does not change the gap percentage. Use the Percentage Calculator separately when you want to track how a single player's source value changed between two dates.
Entered tolerance
The Fair label means only that the computed gap falls inside the percentage you chose. The tolerance is not supplied by Draft Sharks or an industry rule, and widening it should never be used to manufacture approval for an offer already preferred.
Package sums do not model roster consequences
A two-for-one can create an open roster spot, move points from the bench into a starting lineup, or force another player onto waivers. Age, injury, role volatility, contender timeline, replacement options, and future draft-class uncertainty can dominate a small numeric edge. Review each team's post-trade starters, bench, and waiver alternatives after the worksheet balances the packages.
Do not confuse value aggregation with probability multiplication. The Parlay Calculator combines entered betting odds for outcomes that all must win, whereas this page adds values from a fantasy model. The Fixed-Snapshot Fruit Trade Calculator also compares packages, but its fixed site-authored game-item snapshot and physical/permanent states are a different value system. Neither set of numbers can be imported into a fantasy ledger.
Questions for the manager—not the calculator
Use these after the numeric reconciliation and before sending or accepting an offer.
- Does every player and pick use the same source version, scoring format, date, and value unit?
- Which starters, bench players, and roster slots change, and what is the best realistic waiver replacement?
- Is the team competing now, rebuilding, or holding optionality, and does the package serve that timeline?
- Could late news, injury status, pick uncertainty, or a platform trade-review rule alter the decision before processing?
- Keep the boundary explicit: this page is independent and not affiliated with Draft Sharks. It reproduces neither its proprietary rankings nor live player data, and its result is not a performance promise or trade recommendation.
