Prize Money Split Calculator
This calculator helps you distribute a total prize amount among recipients based on a system of relative "shares". Enter the total prize money and a list of shares for each recipient. The calculator will determine the value of a single share and calculate each recipient's portion.
Shares can be any non-negative numbers (e.g., 2, 1.5, 0.5). The split is proportional to these share values. For example, shares of 2, 1, 1 mean the first recipient gets half (2/4) and the other two get a quarter (1/4) each.

Understanding Proportional Prize Splits
Prize money splitting based on shares is a common method in team competitions, partnerships, or group projects where contributions aren't necessarily equal. Instead of a simple even division, participants agree on a relative weighting or "share" of the total prize.
The core idea is:
- Sum up the total number of "shares" assigned to all recipients.
- Calculate the monetary "value" of a single share by dividing the total prize money by the total number of shares.
- Multiply the value per share by the number of shares each recipient holds to find their individual payout.
This method ensures that the prize money is distributed fairly according to the pre-agreed or calculated proportions represented by the shares.
The Calculation Steps
- Identify Total Prize Money (T): This is the amount to be split.
- Identify Individual Shares (s1, s2, ..., sn): These are the share values for each of the 'n' recipients.
- Calculate Total Shares (S): Sum of all individual shares: S = s1 + s2 + ... + sn.
- Calculate Value Per Share (VPS): VPS = T / S.
- Calculate Each Recipient's Amount (Ai): Ai = si * VPS.
This calculator automates these steps for you.
Prize Money Split Examples
See how different share distributions affect the payout:
Example 1: Simple 2:1:1 Split
Scenario: A team of three wins $1000. They agree to split it based on contributions: Player A gets 2 shares, Player B gets 1 share, Player C gets 1 share.
1. Knowns: Total Prize = $1000, Shares = [2, 1, 1]
2. Total Shares: S = 2 + 1 + 1 = 4 shares.
3. Value Per Share: VPS = $1000 / 4 = $250 per share.
4. Split:
- Player A (2 shares): 2 * $250 = $500
- Player B (1 share): 1 * $250 = $250
- Player C (1 share): 1 * $250 = $250
Conclusion: The split is $500, $250, $250.
Example 2: 50/30/20 Percentage Split (using shares)
Scenario: A partnership earns $5000 profit. They agree on a 50%, 30%, 20% split. This can be represented with shares of 50, 30, and 20.
1. Knowns: Total Prize = $5000, Shares = [50, 30, 20]
2. Total Shares: S = 50 + 30 + 20 = 100 shares.
3. Value Per Share: VPS = $5000 / 100 = $50 per share.
4. Split:
- Partner 1 (50 shares): 50 * $50 = $2500
- Partner 2 (30 shares): 30 * $50 = $1500
- Partner 3 (20 shares): 20 * $50 = $1000
Conclusion: The split is $2500, $1500, $1000.
Example 3: Unequal Decimal Shares
Scenario: A small fund of $750 needs to be split among contributors with fractional shares: 1.5, 2, 0.5.
1. Knowns: Total Prize = $750, Shares = [1.5, 2, 0.5]
2. Total Shares: S = 1.5 + 2 + 0.5 = 4 shares.
3. Value Per Share: VPS = $750 / 4 = $187.50 per share.
4. Split:
- Contributor 1 (1.5 shares): 1.5 * $187.50 = $281.25
- Contributor 2 (2 shares): 2 * $187.50 = $375.00
- Contributor 3 (0.5 shares): 0.5 * $187.50 = $93.75
Conclusion: The split is $281.25, $375.00, $93.75.
Example 4: Two Recipients, Simple Ratio
Scenario: $250 prize for a contest with two winners who performed at different levels, split 3 shares to 1 share.
1. Knowns: Total Prize = $250, Shares = [3, 1]
2. Total Shares: S = 3 + 1 = 4 shares.
3. Value Per Share: VPS = $250 / 4 = $62.50 per share.
4. Split:
- Winner 1 (3 shares): 3 * $62.50 = $187.50
- Winner 2 (1 share): 1 * $62.50 = $62.50
Conclusion: The split is $187.50 and $62.50.
Example 5: Equal Split for Multiple Recipients
Scenario: A team of 5 wins $3000. They agree to split it equally.
1. Knowns: Total Prize = $3000, Shares = [1, 1, 1, 1, 1] (Each person gets 1 share for an equal split).
2. Total Shares: S = 1 + 1 + 1 + 1 + 1 = 5 shares.
3. Value Per Share: VPS = $3000 / 5 = $600 per share.
4. Split:
- Recipient 1 (1 share): 1 * $600 = $600
- Recipient 2 (1 share): 1 * $600 = $600
- Recipient 3 (1 share): 1 * $600 = $600
- Recipient 4 (1 share): 1 * $600 = $600
- Recipient 5 (1 share): 600 = $600
Conclusion: Each recipient gets $600. (Entering '1' for each is equivalent to dividing by the number of recipients).
Example 6: Shares Representing Hours Worked
Scenario: $800 bonus to be split based on hours: Person A (15 hours), Person B (10 hours), Person C (5 hours).
1. Knowns: Total Prize = $800, Shares = [15, 10, 5]
2. Total Shares: S = 15 + 10 + 5 = 30 shares.
3. Value Per Share: VPS = $800 / 30 ≈ $26.67 per share.
4. Split:
- Person A (15 shares): 15 * $26.67 ≈ $400.05
- Person B (10 shares): 10 * $26.67 ≈ $266.70
- Person C (5 shares): 5 * $26.67 ≈ $133.35
Note: Small rounding differences may occur with decimals. Sum: $400.05 + $266.70 + $133.35 = $800.10. The tool will handle decimal precision.
Conclusion: Approx. split is $400.00, $266.67, $133.33 (summing to $800).

Frequently Asked Questions about Prize Money Splitting
1. What does "shares" mean in this calculator?
Shares represent the relative proportion or weight assigned to each recipient for the prize money. If one person has 2 shares and another has 1, the first person gets twice as much as the second.
2. Can shares be fractions or decimals?
Yes, shares can be any non-negative number, including integers, decimals, or fractions. The calculator will handle the math.
3. Do the shares have to add up to a specific number?
No, the share values themselves don't need to sum to 100 or any other specific number. The calculator sums whatever share values you enter to find the total number of shares, and then calculates the value of *one* share relative to that total.
4. What if I enter zero shares for a recipient?
If you enter '0' as a share value for a recipient, they will receive $0 from the split, assuming the total prize money is not negative and the total shares among all recipients is greater than zero.
5. What happens if the total prize money is zero?
If the total prize money is $0, then each recipient will receive $0, regardless of their share amount, as there is no money to distribute.
6. What happens if the total shares add up to zero?
If the total sum of all shares entered is zero (e.g., you only enter 0s or leave the share input blank), the calculator will show an error because it's impossible to divide the prize money by zero shares.
7. Can I use this for percentage splits?
Yes. To perform a percentage split (e.g., 60% and 40%), simply enter the percentages as shares (e.g., '60' and '40'). The total shares will be 100, and the value per share will be 1/100th of the total prize, effectively giving you the percentage split.
8. How accurate are the results?
The calculator performs standard floating-point arithmetic. For currency, results are typically rounded to two decimal places for display purposes, but the underlying calculations maintain higher precision before final formatting.
9. Can I split negative amounts (e.g., debt)?
While the calculator can handle negative numbers for the total amount, the concept of "shares" is usually applied to positive distribution. Using it for negative amounts would distribute debt proportionally.
10. How do I add more recipients?
Simply add a new line or comma in the "Shares" input box and enter the share value for the next recipient. The calculator processes each valid number entered as a separate recipient's share.
