How the numbers shift across typical situations for this calculator:
| Scenario | Annual HOA fee growth | Total fee growth |
|---|---|---|
| $3k to $4.5k over 5yr | 8.45% | 50.00% |
| $2.4k to $3.6k over 6yr | 6.99% | 50.00% |
| $4k to $9k over 5yr (Florida condo) | 17.61% | 125.00% |
| $1.8k to $2.1k over 4yr (well-run HOA) | 3.93% | 16.67% |
How This Calculator Works
Enter the starting and ending annual HOA dues and the years between them. The calculator finds the compound annual growth rate that connects the two figures. Special assessments (one-off charges for roofs, elevators, etc.) are separate and not captured in the base dues CAGR.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
HOA dues rising from $3,000 to $4,500 a year over 5 years is an 8.4% annual growth rate, total 50%. HOA fees commonly grow 3% to 8% annually — faster than general inflation, driven by rising insurance (especially in catastrophe-exposed states), maintenance, and reserve-funding requirements. A $3,000 fee growing 6% annually reaches $5,400 in 10 years and $9,600 in 20.
Key Insight
HOA fee growth is an underappreciated homeownership cost — and it's accelerating. Insurance has been the biggest driver: condo master-policy premiums in Florida and California have doubled or tripled since 2020, flowing directly into dues. Underfunded reserves are the hidden time bomb: HOAs that skipped reserve contributions face large special assessments when major systems fail. Before buying into an HOA, review the reserve study and 5-year fee history — a low fee with depleted reserves is more expensive than a higher fee with healthy reserves.
Frequently Asked Questions
How is HOA fee CAGR calculated?
(Ending dues / starting dues) ^ (1/years) − 1. From $3,000 to $4,500 over 5 years is about 8.4% per year.
How fast do HOA fees grow?
Commonly 3% to 8% annually — faster than general inflation. Insurance is the biggest recent driver: catastrophe-exposed states (Florida, California, Colorado) have seen master-policy premiums double or triple since 2020, pushing dues up sharply.
What are special assessments?
One-time charges levied on owners for major expenses not covered by reserves — roof replacement, elevator modernization, structural repairs, post-disaster rebuilding. They can run thousands to tens of thousands per unit and are separate from (and on top of) regular dues.
Why do underfunded reserves matter?
HOAs are supposed to fund reserves for predictable major repairs. Those that skip reserve contributions to keep dues artificially low face large special assessments when systems fail. The 2021 Surfside collapse intensified reserve-funding requirements in many states. Always review the reserve study before buying.
Can I project future dues from this rate?
For near-term budgeting yes, but expect insurance-driven volatility. Recent double-digit growth in cat-exposed areas may moderate or persist depending on the insurance market. Use the historical CAGR plus a margin, and budget separately for the possibility of special assessments.

Methodology & Review
The growth rate is the compound annual rate between HOA dues at the start and end of the period. HOA dues grow with rising maintenance, insurance, and reserve-funding costs. Special assessments (one-off charges for major repairs) are separate and not captured in the base dues CAGR.
