How to Use the HOA Fee Calculator

Enter the unit size (square feet) – Type the internal size of the apartment or unit in square feet.
This allows the calculator to apply the per-square-foot HOA rate correctly.
Enter the HOA rate per square foot (monthly) – Input the monthly HOA charge per square foot (e.g. $0.25/sf/month).
This typically covers building operations such as security, maintenance, insurance, amenities, and management.
Choose how the reserve fund is calculated – Select either:
- Size-based tiers – Common in mixed developments where smaller units pay a lower quarterly reserve and larger units pay more.
- Custom quarterly amount – Useful if the development charges a flat reserve fund regardless of unit size.
Adjust the reserve amounts if needed – Developers or property managers can edit the size thresholds and quarterly reserve figures to match the specific HOA structure of a building.
View your results instantly – The calculator will automatically show:
- Monthly HOA fee
- Quarterly reserve fund
- Monthly equivalent of the reserve fund
- Total yearly HOA cost
Copy your results – Click the “Copy Result” button to save or share the HOA breakdown.

Tip: Prospective buyers should budget HOA fees as a fixed monthly cost, just like a mortgage. Developers can use this tool to test affordability across different unit sizes and price points.
