Dynasty Trade Calculator
Enter your own value for each asset on both sides of a trade, and the calculator totals each side with a depth discount, then tells you whether the trade looks even or favors one side. It uses only the numbers you type, so the answer is as good as your valuations.
Last updated November 4, 2026
0 to 30. Each lower-ranked asset counts (1 − discount) times the one above. 0 is a plain sum.
0 to 50. Sides within this percent of each other count as even.
Enter your own value (0 to 10,000) for each asset on any scale you trust, for example one copied from a ranking source. Draft picks are just assets you value yourself.
Result
Favors Side A
Side A 6,900 vs Side B 6,060: difference 840 (12.17% of the larger side).
Side B is short by 840 adjusted value. One extra asset valued 1,137.04 on Side B would make it even.
Side A: total 6,900
| Asset | Value | Adjusted |
|---|---|---|
| Star | 6,000 | 6,000 |
| Starter | 1,000 | 900 |
Side B: total 6,060
| Asset | Value | Adjusted |
|---|---|---|
| Asset 1 | 3,000 | 3,000 |
| Asset 2 | 2,500 | 2,250 |
| Asset 3 | 1,000 | 810 |
Based only on the values you entered, which are your own subjective valuations, not market data. League format (superflex or 1QB, PPR, TE premium), age, injuries, team context and roster needs are not modelled. For fun and discussion, not advice.

Formula: Sort each side's assets, best first. Adjusted value = value × (1 − discount)^rank, with rank 0 for the best asset. Total = sum of adjusted values. Percent difference = |A − B| ÷ larger total × 100.
- Depth discount 10%, fairness threshold 5%.
- Side A, best asset first: Star 6,000 × 1 = 6,000; Starter 1,000 × 0.9 (1 − 10%)^1 = 900
- Side A total = 6,900
- Side B, best asset first: Asset 1 3,000 × 1 = 3,000; Asset 2 2,500 × 0.9 (1 − 10%)^1 = 2,250; Asset 3 1,000 × 0.81 (1 − 10%)^2 = 810
- Side B total = 6,060
- Difference: 6,900 − 6,060 = 840.
- Percent difference: 840 ÷ 6,900 × 100 = 12.17%.
- Verdict: even up to 5%, slightly favors up to 10%, favors above that. Favors Side A.
- Side B is short by 840 adjusted value. One extra asset valued 1,137.04 on Side B would make it even.
Result: Favors Side A
How the trade is valued
adjusted value = value × (1 − d)^rank
side total = sum of adjusted values
difference % = |A − B| ÷ larger total × 100
Each side is sorted from its most valuable asset to its least. The best asset has rank 0 and counts in full. The second counts (1 − d) times its value, the third (1 − d) squared, and so on, where d is the depth discount you choose. At the default 10%, ranks 0, 1 and 2 count 100%, 90% and 81%. At 0% the discount is switched off and each side is a plain sum.
This is a consolidation model. Many fantasy players hold that one star is scarcer than several mid-level players, because a roster has a limited number of starting spots and a star fills one of them with far more production. Splitting value across many assets therefore usually buys less than the plain sum suggests. The discount is a simple, transparent way to express that belief, and you can raise it, lower it or remove it.
The percent difference is measured against the larger side, so it never exceeds 100%. If it is within your fairness threshold (5% by default) the verdict is even. Up to twice the threshold it reads slightly favors, and above that it reads favors the side with the higher adjusted total.

Where the values come from
This tool has no player list and no live prices, and it never connects to a ranking site. You type a value from 0 to 10,000 for every asset, on any scale you like, for example numbers copied from a ranking you trust or your own sense of worth. The names are optional labels that only you see in the results.
Because every value is your own subjective valuation, two people can enter different numbers for the same player and reach different verdicts. Draft picks work the same way: if you want a pick in the trade, give it the value you think it is worth. The calculator does not invent pick values.
What this calculator does not model
League format is not modelled: superflex or one-quarterback, points per reception, tight end premium and roster size all change what an asset is worth, and so do age, injuries, contract or team context, and your own roster needs. If those matter to you, fold them into the values you enter.
The result is a way to organize your own opinion, not a market price or a prediction. Use it for discussion and for fun, and make your own decisions.
How to use the Dynasty Trade Calculator
- Enter an optional name and your own value (0 to 10,000) for each asset on Side A and Side B, using Add asset for up to 10 per side.
- Set the depth discount (0 to 30%) and the fairness threshold for an even trade.
- Read the verdict, the adjusted totals and the gap the trailing side would need to add.
- Open Show the work to check each adjusted value, then Copy, Print or Share the result.
Worked example
Side A trades a 6,000 star and a 1,000 starter. Side B offers three assets valued 3,000, 2,500 and 1,000, with the default 10% depth discount. Side A totals 6,900 and Side B totals 6,060. The difference is 840, which is 12.17% of the larger side, above twice the 5% threshold, so the trade favors Side A. Side B would need to add one asset valued about 1,137.04 to match.
| Side | Asset value | Rank weight | Adjusted |
|---|---|---|---|
| A | 6,000 | 1 | 6,000 |
| A | 1,000 | 0.9 | 900 |
| B | 3,000 | 1 | 3,000 |
| B | 2,500 | 0.9 | 2,250 |
| B | 1,000 | 0.81 | 810 |
| Totals | A 6,900 | B 6,060 | Difference 840 |
Frequently asked questions
Does this use real player values or live market data?
No. It has no player database and never loads data. You enter every value yourself, so the result only reflects your own numbers.
What is the depth discount for?
It makes each lower-ranked asset on a side count a little less, because stars are scarcer than depth. Set it to 0% for a plain sum.
How is the even, slightly favors and favors verdict decided?
The percent difference is compared with your fairness threshold: within it is even, up to twice it is slightly favors, and anything above favors the higher side.
Does it account for league format, age or injuries?
No. Superflex or one-quarterback, scoring, tight end premium, age, injuries and roster needs are not modelled, so reflect them in the values you enter.
Is anything saved or sent anywhere?
No. The math runs in your browser, and a shared link carries only the names, values and settings you entered.
