Impact Fee Calculator
Impact fees fund public infrastructure. This calculator totals fees by category.
Total impact fees
$1,953,000
Per unit total
$10,850
Transportation total
$810,000
How the math works
Per unit = school + transportation + parks + other. Total = per unit × units.
Impact fees often get waived or reduced for agreed-upon infrastructure contributions. Explore credit-in-lieu options with planning staff before paying fees in cash — a $200k park dedication can offset $500k in fees, changing deal economics significantly.

How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
