    Algorithm Overview

    The Tarkov flea market is governed by a complex algorithm that determines listing fees, search rankings, and sale eligibility. Understanding these mechanics gives you a significant advantage over players who just guess at prices.

    The core components of the flea market algorithm include:

    Fee Calculation

    A dynamic formula based on item base value and your listing price

    Reputation System

    Tracks your trading history and affects listing capacity

    Listing Limits

    Caps on active offers based on reputation level

    Search Ranking

    Determines which listings appear first for buyers

    The Fee Formula

    Flea market fees are calculated using a logarithmic formula that penalizes listings priced significantly above or below the item's base value. The formula is:

    Fee = VÔéÇ ├ù Ti ├ù 4^Po ├ù Q + Vr ├ù Tr ├ù 4^Pr ├ù Q

    V = Item base value (set by BSG)

    Vr = Your listing price (per item)

    Ti = 0.025 (base fee rate)

    Tr = 0.01 (requirement fee rate)

    Po = log(V/Vr) clamped to 0 (overpricing penalty)

    Pr = log(Vr/V) clamped to 0 (requirement factor)

    Q = Quantity of items

    What This Means in Practice

    • Listing at base value: Minimum fee (~2.5% of item value)
    • Listing at 2x base value: Fee increases moderately
    • Listing at 10x base value: Fee can exceed 30% of listing price
    • Extreme overpricing: Fees can be higher than the sale price!

    Reputation System

    Your flea market reputation is a number that increases based on your trading activity and decreases when you cancel listings or fail to fulfill sales.

    How Reputation Changes

    +0.01 Per successful sale

    +0.01 Per successful purchase

    -0.01 Per cancelled listing

    -0.03 Per expired offer (unsold)

    Building reputation takes time but provides significant benefits. High-reputation players can list more items simultaneously and are less affected by listing failures.

    Listing Limits

    The number of active offers you can have depends on your reputation level:

    ReputationMax Offers
    0.00 - 0.193 offers
    0.20 - 0.995 offers
    1.00 - 9.9910 offers
    10.00 - 29.9920 offers
    30.00 - 99.9950 offers
    100.00+100+ offers

    Pro tip: If you're near a reputation threshold, prioritize completing sales rather than listing new items to maximize your offer slots.

    Price Ranking Algorithm

    When a buyer searches for an item, listings are ranked by price (lowest first). However, there are some nuances:

    • Listings are grouped by exact price first
    • Within the same price, older listings appear first
    • Durability and condition affect which listings are shown for equipment
    • Ammo stacks are ranked by price per round

    Undercut Strategy

    Undercutting by just 1₽ places your listing at the top. However, if fees make your profit negative, it's better to match the lowest price and wait.

    Optimization Tips

    1. Upgrade Intel Center

    Intel Center levels reduce flea market fees. Level 3 reduces fees by 30% - a massive savings on high-value items.

    2. Use Hideout Management

    Each Hideout Management skill level slightly reduces fees. Combine with Intel Center for maximum savings.

    3. Price Strategically

    Check fee breakpoints. Sometimes listing at 90% of market price yields more profit than listing at 100% due to fee scaling.

    4. Avoid Cancellations

    Every cancellation hurts reputation. Set realistic prices from the start instead of relisting multiple times.
