Binary bv 2/1 matching calculation

 A binary BV (Business Volume) 2/1 matching calculation is typically used in MLM (Multi-Level Marketing) to calculate commissions based on the sales volume generated by the distributors in a binary tree structure. In a binary MLM plan, each distributor has two legs (left and right).


### Key Concepts


1. **Binary Tree Structure**:

   - Each distributor recruits two other distributors, forming two legs: left and right.


2. **Business Volume (BV)**:

   - This is the total sales volume generated by the products sold within a distributor's network.


3. **Matching Criteria**:

   - Commissions are often based on matching BV in a 2/1 ratio (or other ratios like 1/1, 3/1, etc.).


### Steps for Calculation


1. **Accumulate BV in Both Legs**:

   - Calculate the total BV for the left leg and the right leg separately.


2. **Apply Matching Ratio (2/1 in this case)**:

   - Identify pairs of BV units that meet the 2/1 matching criteria.


### Example Calculation


Let's assume:

- Left leg BV = 5000

- Right leg BV = 3000

- Matching ratio = 2/1


#### Step-by-Step Calculation:


1. **Determine Matching Pairs**:

   - For each 2 BV units in the left leg, 1 BV unit in the right leg is required.

   - Number of pairs that can be formed = Minimum (Left leg BV / 2, Right leg BV)


2. **Calculate the Number of Matches**:

   - Matches = Min(5000 / 2, 3000)

   - Matches = Min(2500, 3000)

   - Matches = 2500 pairs


3. **Calculate Matched BV**:

   - Matched BV from left leg = Matches * 2 = 2500 * 2 = 5000

   - Matched BV from right leg = Matches * 1 = 2500 * 1 = 2500


4. **Calculate Remaining BV**:

   - Remaining BV in left leg = 5000 - 5000 = 0

   - Remaining BV in right leg = 3000 - 2500 = 500


5. **Commission Calculation** (if applicable):

   - If the commission rate is X per matched BV, then Total Commission = Matches * X


### Example with Values:

Assume the commission rate is ₹10 per matched BV pair:

- Total Commission = 2500 pairs * ₹10 = ₹25,000


### Implementation in PHP:


Here’s a basic PHP code snippet to illustrate this calculation:


```php

<?php

function calculateBVCommission($leftBV, $rightBV, $commissionRate, $matchingRatioLeft, $matchingRatioRight) {

    // Calculate the number of matching pairs

    $matches = min(floor($leftBV / $matchingRatioLeft), floor($rightBV / $matchingRatioRight));


    // Calculate matched BV

    $matchedBVLeft = $matches * $matchingRatioLeft;

    $matchedBVRight = $matches * $matchingRatioRight;


    // Calculate remaining BV

    $remainingBVLeft = $leftBV - $matchedBVLeft;

    $remainingBVRight = $rightBV - $matchedBVRight;


    // Calculate total commission

    $totalCommission = $matches * $commissionRate;


    return [

        'matches' => $matches,

        'matchedBVLeft' => $matchedBVLeft,

        'matchedBVRight' => $matchedBVRight,

        'remainingBVLeft' => $remainingBVLeft,

        'remainingBVRight' => $remainingBVRight,

        'totalCommission' => $totalCommission

    ];

}


// Example values

$leftBV = 5000;

$rightBV = 3000;

$commissionRate = 10;

$matchingRatioLeft = 2;

$matchingRatioRight = 1;


$result = calculateBVCommission($leftBV, $rightBV, $commissionRate, $matchingRatioLeft, $matchingRatioRight);


print_r($result);

?>

```


This code calculates the number of matching pairs, matched BV, remaining BV, and the total commission based on the given BV values and matching ratios. Adjust the `commissionRate`, `matchingRatioLeft`, and `matchingRatioRight` as needed for your specific MLM plan.
