The Fed sets one interest rate. Your metro sets your real one. At these assumptions, moving from Austin to Raleigh changes the housing component of Aspire Rate by roughly four points. The Fed has not moved rates by four points in a single year since 1980.
Most personal finance writing treats inflation as a national variable. CPI ticks up, the Fed responds, your rate environment shifts. That's the macro story. It's true. It's also incomplete to the point of misleading.
The cost of the life you're actually building — a house in your zip, a school for your kid, a hospital you'd accept — is an intensely local number. Zillow's metro home price indices vary across US metros by a wider band than the Fed's policy rate has moved in 40 years.
The numbers, rounded
Five-year trailing CAGR through April 2026, by metro housing market:
- Austin, TX — roughly 9.2%
- Raleigh, NC — roughly 5.4%
- Phoenix, AZ — roughly 8.1%
- New York, NY — roughly 4.2%
- Boston, MA — roughly 6.3%
- Atlanta, GA — roughly 7.5%
- Detroit, MI — roughly 5.0%
These are rough working figures from Zillow's ZHVI series. Final numbers and full source vintages are in the Methodology page.
The spread between the highest and lowest of these is 5 percentage points of CAGR — every year, compounding. Over a 10-year horizon, that's the difference between a $500K starter home in 2026 costing $1.2M in 2036 (Austin pace) versus $815K (NYC pace). Same down-payment goal. Different lifetime gap.
What this means for Aspire Rate
If your goals basket weights housing at 30 to 50 percent (most do, in the Home and Family preset baskets), shifting your zip changes Aspire Rate proportionally. At these assumptions, swapping Austin for Raleigh in a Home basket weighted 50% to housing closes roughly 1.9 points of Aspire Rate floor. That's a bigger move than the Fed has made in a single meeting in two decades.
This isn't a recommendation to move. Geography is the most expensive lever in the Simulator and the one with the most non-financial weight. "Move to Raleigh" sounds like a savings strategy when you write it next to a CAGR. It's actually a life decision with kids, schools, networks, and identity attached. The math is just a way to see what's actually being traded.
Why the Fed gets the headlines anyway
Two reasons. First, the Fed is visible — meetings, announcements, dot plots. Local housing indices are a quiet quarterly Zillow update most people never read. Second, the Fed's rate affects what you pay on debt; your metro's CAGR affects what you aspire to buy. The first hits your monthly cash flow; the second sits in the background until you try to actually buy.
Personal finance writing optimizes for what feels urgent. It should also pay attention to what's structural.
What to do with this
Run Aspire Rate at your current zip in the Calculator. Then move to the Simulator and switch the Geography lever to a comparable metro. Watch what happens to your Aspire Gap. If the swing is large, that's information — not a directive.
