Interactive Planner
Fill-Rate & Recruit Planner
Work backward from a dollar goal. Enter the amount you need to raise, and see how many fundraisers it takes at different fill rates. Face value for a 31-day calendar is $496. At 75% fill, you'd need ~14 fundraisers to model a $5,000 campaign.

How many fundraisers do you need?
Enter your goal and adjust assumptions. The planner shows fundraiser counts at different fill rates so you can present scenarios to your board or leadership.
Work backward from your goal

How many people have already agreed to share calendars?
Typical planning bands: 60–75% conservative, 85–100% optimistic.

Modeled estimates only—not guarantees. Totals depend on roster, outreach, and donor generosity. Over-gives (donors giving more than Day N) can push totals higher.
How the fill-rate planner works
Enter your fundraising goal
Set the dollar amount your campaign needs. This is the number the planner will work backward from.
Choose your month length
Select 28, 29, 30, or 31 days. Face value changes accordingly (31 days = $496 per calendar).
Optionally enter committed fundraisers
If you already have people confirmed, enter that count to see the recruitment gap.
Adjust planning fill rate
Use the slider to model optimistic (85–100%) or conservative (60–75%) assumptions. The planner shows scenarios across the range.
Review your recruit plan
See how many fundraisers you need, the gap vs. committed roster, and weekly checkpoint targets. Share this with your board or leadership team.
Fundraisers needed by goal (31-day month)
Quick reference for common goals. Formula: fundraisers ≈ goal ÷ ($496 × fill rate).
These are modeled scenarios—not guarantees.
| Goal | 60% fill | 75% fill | 100% fill |
|---|---|---|---|
| $2,500 | 9 | 7 | 6 |
| $5,000 | 17 | 14 | 11 |
| $10,000 | 34 | 27 | 21 |
| $15,000 | 51 | 41 | 31 |
Example: A $10,000 goal at 75% fill needs ~27 fundraisers (each sharing their own calendar). At 100% fill, it's 21 fundraisers. Over-gives can reduce headcount further.
Fill-rate planner vs. calculator
Both tools use the same formula. The planner works backward from a goal; the calculator works forward from a roster size.
| Dimension | Fill-Rate Planner | Calculator |
|---|---|---|
| Direction | Backward: goal → roster | Forward: roster → estimate |
| Primary input | Dollar goal | Fundraiser count |
| Primary output | Fundraisers needed | Modeled total |
| Use case | Board planning, recruitment targets | Campaign modeling, "what if" scenarios |
| Secondary | Fill-rate scenarios, weekly checkpoints | Face value tables |
Use both: plan your roster with the planner, then model "what if" scenarios with the Calculator →
Common questions
Answers about fill rate, the math, and planning your roster.
Fill rate is the percentage of day slots claimed across all fundraiser calendars. 100% fill means every day on every calendar is claimed at face value or more. 75% fill means three-quarters of days are claimed on average. Fill rate is the biggest variable in campaign totals after roster size.
Use the inverse formula: fundraisers ≈ goal ÷ (face value × fill rate). Example: $5,000 goal ÷ ($496 × 75%) ≈ 14 fundraisers at 31-day, 75% fill. The planner calculates this automatically for different fill assumptions.
Model forward estimatesMost organizers plan for 60–75% as a working band. Treat 100% as the face-value ceiling, not the base case. A smaller roster that fills most days often outperforms a large roster of empty calendars. The planner shows scenarios at 60%, 75%, 85%, and 100% fill.
The calculator works forward: enter fundraiser count and fill rate → see modeled total. The fill-rate planner works backward: enter a goal → see how many fundraisers you need at different fill rates. Same math, opposite direction.
Open calculatorNo. All numbers are modeled planning scenarios—not promises. Actual totals depend on how many fundraisers you recruit, how well they share their calendars, and whether donors give at or above face value. Over-gives can push totals higher than the base estimate.
Weekly checkpoints are illustrative pacing targets—not guarantees. They suggest how fill might progress over the month (e.g., ~25% by end of Week 1, ~50% by Week 2). Use them to gauge momentum, not as a contract.
