Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual property tax growth | Total tax growth |
|---|---|---|
| $4k to $5.5k over 5yr | 6.58% | 37.50% |
| $2k to $2.5k over 10yr (capped) | 2.26% | 25.00% |
| $8k to $14k over 6yr (boom market) | 9.78% | 75.00% |
| $3k to $3.2k over 3yr | 2.17% | 6.67% |
How This Calculator Works
Enter the starting and ending annual property tax bills and the years between them. The calculator finds the compound annual growth rate that connects the two figures. Growth comes from two sources combined: assessment increases (market or assessed value) and rate increases (mill rate).
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
A property tax bill rising from $4,000 to $5,500 over 5 years is a 6.6% annual growth rate, total 37.5%. That's roughly double general inflation. Many homeowners are surprised by this trend — property tax often grows faster than wages, becoming a larger share of housing cost over time.
Key Insight
Property tax growth varies dramatically by jurisdiction and policy. States with assessment caps (California Prop 13, Texas homestead, Florida Save Our Homes) limit annual growth typically to 2% to 3% for primary residences. States without caps or with frequent reassessments can see double-digit annual growth during market rallies. The protection is biggest for long-term owners; new buyers typically reset to market value at purchase.
Long-run U.S. property tax growth
U.S. local property tax revenue grew at ~4-5% CAGR nationally from 1990-2024 (Census Bureau data). Substantially higher than 3% general inflation. Difference reflects (a) rising home values, (b) local government expansion of services, (c) school funding pressure.
Individual property tax CAGR depends on jurisdiction. California Prop 13-protected properties: 2% max annual CAGR. Florida Save Our Homes: 3% max. Texas (no income tax): often 5-8% CAGR. New Jersey: similar.
For new homeowners: model 3-5% annual property tax increase in long-term financial projections. For long-tenured California or Florida residents: model 2-3% per cap rules. Substantial difference compounds dramatically over decades.
Geographic patterns in property tax CAGR
Property tax CAGR varies by region and state. RAPID GROWTH areas: Texas suburbs, much of Florida, California new construction, Phoenix metro. Often 5-8% annual increase reflecting rising home values + local rate increases.
MODERATE GROWTH areas: Midwest, slower-growth Southeast, much of Southwest. Often 3-4% annual.
LOW GROWTH areas: declining-population markets (Detroit, Cleveland), stable mature markets (Vermont, Mass.). Often 2-3% annual.
Cap-protected: California Prop 13 properties (2% max), Florida Save Our Homes (3% max) — long-tenured owners locked at low CAGR despite market growth.
Implications for retirement planning. Retirees on fixed income face property tax growth substantially exceeding Social Security COLA (~3%) and most pensions (often no COLA). For long-term retirement affordability, factor property tax CAGR specifically; choose lower-CAGR markets when possible.
U.S. property tax CAGR by region (2010-2023 typical)
Reference property tax CAGR by region for typical owner-occupied primary residence.
| Region/State | Typical CAGR | Drivers |
|---|---|---|
| California (Prop 13) | 2-2.5% | Constitutional cap |
| Florida (Save Our Homes) | 2.5-3.5% | Cap + new growth above cap |
| Texas growth metros | 5-8% | No income tax; growth |
| NY/NJ/CT suburbs | 3-5% | Annual assessment; aging infrastructure |
| U.S. national avg | 4-5% | Above general inflation |
| Midwest stable | 3-4% | |
| Vermont | 2-3% | Slow growth |
| Detroit/Cleveland | 2-3% or less | Declining values |
Property tax CAGR substantially exceeds general inflation (3% CPI) in most U.S. markets, particularly growth markets. For 30-year housing affordability projection, use 4-5% property tax CAGR as baseline; adjust for jurisdiction-specific factors.
Frequently Asked Questions
How is property tax CAGR calculated?
(Ending tax / starting tax) ^ (1/years) − 1. From $4,000 to $5,500 over 5 years is about 6.6% per year.
How fast does property tax typically grow?
Without assessment caps: often 4% to 8% annually in normal markets, faster during real-estate booms. With assessment caps (California Prop 13, Texas homestead): typically 2% to 3% per year on primary residences. New construction and recent purchases face full reassessment.
Why is my property tax growing so fast?
Two drivers: assessment increases (the assessor revalued the property higher) and rate increases (the taxing district raised the mill rate). Often both happen together during property booms. Some growth is also from special assessments (bonds, fire districts) layered onto base tax.
Can I appeal an assessment?
Yes — most jurisdictions allow annual appeals during a defined window. Success rates vary; documented evidence (comparable sales lower than your assessment, property defects, errors in characteristics) gets results most often. Many homeowners successfully reduce assessment by 5% to 15%.
What about exemptions?
Many jurisdictions offer homestead, senior, veteran, and disability exemptions that reduce taxable assessed value or impose caps on growth. These can substantially reduce the tax bill for qualifying owners — always check eligibility annually.
When is this calculator unreliable?
As forward projection because future property tax depends on assessment cycle decisions, local rate changes, and any cap provisions specific to jurisdiction. Past CAGR is informative but not determinative. For long-term planning in cap-protected jurisdictions (CA Prop 13, FL Save Our Homes), assume CAGR at or near cap; in growth markets, assume 4-6% CAGR baseline.

Methodology & Review
Property tax CAGR equals (final tax / initial tax)^(1/years) − 1, expressed as a percentage. The calculator returns annualized growth rate of property tax over multi-year period. Useful for projecting future property tax based on historical pattern, comparing tax burden growth across jurisdictions, or evaluating long-term affordability of homeownership. RELIABILITY: Reliable as backward-looking calculation. Less reliable as forward projection because property tax CAGR depends on local government revenue needs, assessment cycles, and any cap provisions — not constant across time. Past CAGR informs but doesn't determine future increases.
