Retiring in Boise, ID: What You Need to Know

Boise's biggest FIRE risk is its own success — home prices tripled between 2015 and 2024, pricing out many newcomers. If you already own, you're sitting on significant equity. Idaho's income tax is a flat 5.8%, but the state offers a grocery tax credit and retirement deductions. Boise's real FIRE appeal is lifestyle arbitrage: outdoor activities (skiing at Bogus Basin, floating the Boise River, hiking the Foothills) are essentially free, replacing expensive urban entertainment. Many Boise FIRE retirees report spending less in retirement because their hobbies cost nothing.

What Does $1,125,000 Get You in Boise, ID?

With a FIRE number of $1,125,000, you can safely withdraw $45,000 per year ($3,750/month) to cover living expenses in Boise, ID. This follows the 4% rule — the widely-used benchmark that says a diversified portfolio can sustain a 4% annual withdrawal rate indefinitely.
