How this calculator works
Three simple inputs. Seven powerful outputs. All in real-time.
Enter your foundation size
Tell us how many employees are in your health system. The calculator works for foundations with 500 to 200,000+ employees.
Share your current giving rate
What percentage of your employees currently participate in giving? Most foundations report 5–15%. We'll show you the gap.
Input average gift size
Your average annual gift per donor. Typically $100–$1,000 for payroll deduction. You can adjust this based on your giving program.
See your revenue potential
We calculate current giving, projected giving (at 30% participation), Roster's cost, and your net ROI—all updated as you adjust the sliders.
The metrics that matter
Here's exactly what the calculator reveals about your opportunity.
Current Annual Giving
What your foundation is receiving today, based on current participation and gift size.
Formula: Employees × Current Participation % × Average Gift
Projected Annual Giving with Roster
Revenue at 30% participation. This is the benchmark we see when hospitals implement Roster's engagement program.
Formula: Employees × 30% × Average Gift
New Revenue Potential
The incremental revenue Roster helps you capture. This is the "upside" available to your foundation.
Formula: Projected Giving − Current Giving
Roster Annual Cost
Zero risk pricing. 5% of new revenue we help you generate, plus $300/month ($3,600/year) platform fee. You only pay if we deliver.
Formula: (New Revenue × 5%) + $3,600
Net ROI (Your Profit)
Money in your pocket. The new revenue we unlock, minus what you pay Roster. This is the bottom-line impact on your giving program.
Formula: New Revenue − Roster Cost
ROI Multiple
For every $1 you invest in Roster, how much new revenue do you receive? Most foundations see 3–5x returns in year one.
Formula: New Revenue ÷ Roster Cost
Payback Period
How many months until Roster's cost is covered by new revenue alone? Most foundations break even in 1–3 months.
Formula: Roster Cost ÷ (New Revenue ÷ 12 months)
Common questions
What if our current participation rate is different? ▼
Adjust the "Current Participation Rate" slider to match your foundation's actual number. If you're at 8%, or 15%, or 2%, the calculator will recalculate your opportunity instantly. The ROI will shift accordingly.
Is 30% participation realistic? ▼
Yes. Hospitals we work with—ranging from 2,000 to 65,000 employees—have achieved 25–35% participation within 12 months of launching Roster's engagement program. This comes from better onboarding, reminders, and a seamless payroll experience. We use 30% as a realistic middle ground. Your mileage may vary based on employee engagement and communication.
What does the 5% success fee cover? ▼
The success fee aligns our incentives with yours. We only profit when your giving grows. It covers the platform, our support team, AI-driven personalization, and ongoing optimization of your donor engagement strategy. The $300/month platform fee is our baseline cost regardless of revenue—it includes hosting, security, integrations, and 24/7 support.
Can I test these numbers with my team? ▼
Absolutely. Play with the sliders. Try your current giving rate, then see what happens at different participation levels. You can also ask us to model specific scenarios in a personalized demo. Many foundations share the calculator internally to build board consensus around the investment.
Does Roster work for foundations with low participation rates? ▼
Yes. In fact, foundations with lower participation rates often see the biggest absolute gains when they implement Roster. If you're at 5% today and move to 30%, that's a massive upside. Even foundations at 20% participation have captured 10–15 additional percentage points with us. The engagement program works across all starting points.
