Fantasy Baseball Trade Calculator

Fantasy baseball is an online game where participants act as general managers of virtual baseball teams. Players draft real-life Major League Baseball (MLB) players, and their teams accumulate points or rankings based on the actual statistical performance of those players in real games. The goal is to build the best team and outperform opponents in various statistical categories or total points throughout the baseball season.

Leagues can be structured in different ways, most commonly as **Rotisserie (Roto)** or **Points** leagues. In Roto leagues, teams compete in specific statistical categories (e.g., Home Runs, RBIs, Wins, ERA) and are ranked based on their performance in each category. In Points leagues, players earn points for various statistical achievements (e.g., a single might be 1 point, a home run 4 points, a strikeout 1 point). Trading players is a key aspect of managing a fantasy team, allowing managers to acquire players who better fit their team's needs or improve their overall value.

This Fantasy Baseball Trade Calculator helps you assess the fairness of a trade by comparing the Rest-of-Season (ROS) values of players involved. Here's a breakdown of its functionality:

• Player Values: The calculator uses a predefined dataset of player values (ROS Auction Values and $ per Game). These values are estimates of a player's worth for the remainder of the season, derived from mock projections.
• League Platform Selection: Choose your fantasy league platform (ESPN, Yahoo, Sleeper, Other). Note that this calculator does **not** support direct import or syncing of your league roster due to technical limitations (API access, cross-origin restrictions).
• League Type Selection: Choose between "Rotisserie (Roto)" or "Points" league types. This selection dynamically adjusts the relevant settings and calculation methodology.
• Value Metric: Select whether to evaluate trades based on "Rest-of-Season Auction Value ($)" (using a conceptual $260 budget) or "$ per Game" (a performance-only metric).
• Customizable Settings:
  • Roto Leagues: You can select the specific categories your league uses (e.g., 5x5, 6x6, including categories like Holds and Quality Starts). The calculator will sum up the player's pre-calculated contributions to these selected categories.
  • Points Leagues: You can set custom point values for various offensive and pitching statistics (e.g., Home Runs, RBIs, Wins, Strikeouts, Walks, Innings Pitched). The calculator will then compute each player's total points based on these weights.
  • League Size: Input your league's team count (8-16 teams). While this does not dynamically adjust player values in this static version, it helps you contextualize the trade within your league's competitive landscape.
• Adding Players: Use the search bars to find and add players to "Team A Gives" and "Team B Gives". The search is dynamic and will suggest players from our internal mock database. You can add multiple players per side.
• Real-time Analysis: As players are added or removed, the calculator instantly updates the total value for each team and calculates the net difference.
• Trade Suggestions: Based on the value difference, the calculator provides a basic suggestion on which team is gaining or losing value, helping you identify if a trade is balanced or needs adjustment.

Remember, this tool is a guide. Actual trade value can also depend on your specific team needs, league competitiveness, and future outlook for players. It's always a good practice to cross-reference with multiple resources.

1. Configure League Settings:
   • Select your "Platform" (e.g., ESPN, Yahoo). This is for context only.
   • Select your "League Type" (Rotisserie or Points).
   • Choose your preferred "Value Metric" (Rest-of-Season Auction Value or $ per Game).
   • Enter your "League Size" (e.g., 12 teams).
   • If "Rotisserie" is selected, check the boxes for the categories used in your league (e.g., R, HR, RBI, SB, AVG for hitters; W, K, ERA, WHIP, SV, HLD, QS for pitchers).
   • If "Points" is selected, adjust the point values for each statistical category to match your league's scoring system.
2. Add Players to Trade:
   • In the "Team A Gives" section, type a player's name into the search bar. A list of matching players from our mock database will appear.
   • Click on a player from the search results to add them to Team A's trade package.
   • Repeat the process for "Team B Gives" to add players from the other side of the trade. You can add up to 3-5 players per side to simulate typical trade scenarios.
3. Review Trade Analysis:
   • The "Total Value" for each team will update automatically as players are added or removed.
   • The "Value Difference" will show the net gain or loss for Team A (Team A Value - Team B Value).
   • A "Trade Suggestion" message will appear, indicating if the trade is balanced or if one side is getting more value. For example, "Team A is gaining $5.00 in value. Team B should ask for more!"
4. Adjusting Players & Balancing Trades:
   • To remove a player from a trade package, click the 'X' button next to their name.
   • If the trade is unbalanced, consider adding or removing players from either side to achieve a fairer deal. The suggestion will guide you on the approximate value needed.
   • Pro Tip: Always cross-reference trade values with multiple reputable fantasy baseball tools (e.g., Razzball, FantasyPros, FanRanked) to get a well-rounded perspective.

This graph visually represents the total value of players for each side of the trade, making it easy to see the balance at a glance.

The height of each bar represents the total value of players on that side of the trade. A perfectly balanced trade would show bars of equal height.
