Donation Allocation Planner
A weighted allocation can divide a fixed pool across destinations without requiring the weights to sum to 100. The calculator normalizes the three entered weights into shares of the total budget.
How to use this calculator
- Enter a total and non-negative weights; at least one weight must be positive.
- Check that units, denominator definitions and time periods are consistent before comparing scenarios.
- Run a second scenario when an assumption is uncertain.
Formula used by donation allocation planner calculator
Each destination receives total budget × its weight / sum of all destination weights.
- Each destination receives total budget × its weight / sum of all destination weights.
- Check recipient eligibility, legal requirements and any religious or organizational guidance separately. No donation or transfer is made by this tool.
- The tool performs arithmetic on the values entered and does not validate assumptions against outside records.
Worked examples
Worked example
€1,200 budget with weights 40, 35 and 25.
The shares are 40%, 35% and 25%, allocating €480, €420 and €300.
The budget is distributed proportionally to the entered non-negative weights.
