Dynasty calculator comparison hub
A market-based KeepTradeCut alternative
All three are free dynasty trade calculators — the difference is where the values come from and what happens after you calculate. Honest breakdown, updated Aug 30, 2026.
The useful moment is when the calculators disagree.
That gap shows where crowd perception and completed-trade market data price a player differently. Run the exact package, then decide with your roster window.
| TradeGauge | KeepTradeCut | FantasyCalc | |
|---|---|---|---|
| Where values come from | Market values from Dynasty Dealer, built on real dynasty trade data | Crowdsourced — users vote on "which player would you rather have" | Derived from real league trades (Sleeper/MFL data) |
| Price | Free, no account | Free (supported by sponsors/promos) | Free |
| Formats | Dynasty market values + full redraft mode (SF/1QB × PPR/Half/Standard) | Dynasty & redraft, SF and 1QB | Dynasty & redraft, SF and 1QB |
| Rookie picks | 2026–2028 picks valued and searchable | Yes | Yes |
| Shareable trade links | Yes — every trade gets a URL | Yes | No native share links |
| Value alerts | Email alerts + live iOS app — get pinged when values move | No push alerts | No |
| Interface | Fast static pages, dark, mobile-first, zero clutter | Full-featured but denser UI | Minimal, utilitarian |
Use TradeGauge when…
you want the fastest verdict, a link to paste in league chat, and alerts when the values behind a pending trade move.
Use KeepTradeCut when…
you want to know how the crowd feels about players, or you enjoy voting on "would you rather" matchups that power their values.
Use FantasyCalc when…
you want a second market-based opinion or their public API for your own spreadsheet projects.
Looking for a KeepTradeCut API?
KeepTradeCut doesn't publish a documented public API, which is why people end up scraping the site or copying the chart into a spreadsheet by hand. TradeGauge serves the same values it renders from a plain read-only JSON endpoint — no key, no account, no rate-limit signup.
curl https://tradegaugehq.com/api/values/dynastyEach row is [sleeperId, name, position, team, value, age], so it joins straight onto Sleeper data. Datasets: dynasty, plus six redraft tables — redraft-sf-ppr, redraft-sf-half, redraft-sf-std, redraft-1qb-ppr, redraft-1qb-half, redraft-1qb-std. The x-values-fetched-at response header tells you how fresh the snapshot is.
Want your AI assistant to do the joining instead of a script? The same data is exposed as six tools on the free TradeGauge MCP server — connect it to Claude, ChatGPT, or Cursor and ask trade questions in plain English.
Values come from Dynasty Dealer, whose terms allow reuse with a visible attribution link wherever the values appear — keep that credit on anything you publish with them.
Try it on your trade right now — the dynasty trade calculator needs no account, or start from the value chart andrankings. If FantasyCalc is the tool you are replacing or double-checking, use the dedicatedFantasyCalc alternative calculator.

- Is TradeGauge a good KeepTradeCut alternative?
- If you want a fast, clean calculator with market-based values, shareable trade links, and value alerts, yes. If you specifically want crowdsourced values and the "would you rather" voting game, KTC remains the reference for that approach — the two are honest complements.
- Why do TradeGauge and KeepTradeCut values disagree sometimes?
- Different sources: KTC values are votes about perception; TradeGauge values track what the market pays in actual trades. When they disagree, the gap itself is information — perception hasn't caught up to the market (or vice versa), which is exactly where good trades live.
- Which calculator should I trust for my trade?
- Run the trade through more than one — it takes seconds. If every calculator calls it a win, accept with confidence. If they split, the trade is close enough that roster fit and your contention window should decide.
- Does KeepTradeCut have a public API?
- Not a documented one, which is why most projects scrape the site. TradeGauge serves the values it renders from an open read-only endpoint: a GET to https://tradegaugehq.com/api/values/dynasty returns rows of sleeperId, name, position, team, value and age with no key or account, plus six redraft datasets. The same data is available to AI assistants through the free TradeGauge MCP server.
- Is FantasyCalc's approach different?
- FantasyCalc computes values from real league trades, which is philosophically closest to what TradeGauge uses (Dynasty Dealer market data). The main differences are the interface, shareable links, and TradeGauge's alerts.
