FAQ
Can grant writers take a percentage of the award?
No. Commission-based grant writing violates the AFP Code of Ethical Standards and most funders prohibit paying fundraising costs from award funds. Charge hourly or by project.
What win rate is normal?
Roughly 10–20% on cold federal or new foundation prospects, and 50–70% on renewals with existing funders. Prospect research is what moves your portfolio toward the higher band.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
