Enter two numbers from your property tax notice and this calculator estimates your Save Our Homes savings, your homestead exemption, and how much of that benefit you could take with you to a new Florida home.

Save Our Homes benefitJust value minus assessed value: the part of your home's worth that the cap shields from taxation. It grows each year the market outpaces the 3 percent cap.$300,000
Estimated yearly savings from the capThe tax you avoid because you are taxed on the assessed value instead of the just value. Benefit multiplied by your tax rate.$6,000
Estimated yearly savings from the exemptionThe homestead exemption removes up to $50,000 of assessed value from taxation. The second $25,000 skips school taxes and adjusts with inflation, so treat this as an estimate.$1,000
Total estimated yearly savings$7,000

How the numbers work

Florida taxes homesteaded homes on their assessed value, not their market value. Under the Save Our Homes cap, that assessed value can rise at most 3 percent a year, even when the market jumps. After a few years of rising prices, the gap between what your home is worth and what you are taxed on becomes real money. The calculator above turns that gap into an estimated dollar figure.

The homestead exemption then removes up to $50,000 of assessed value from taxation on your permanent residence. You apply once with your county property appraiser, generally by March 1, using Form DR-501.

Portability lets you carry up to $500,000 of your Save Our Homes benefit to the next Florida home, so moving does not mean starting from zero. The rules have sharp edges: deadlines, deed language, and co-owner situations can shrink the portable amount to nothing. Our article on what happens to homestead when one owner moves out walks through the biggest trap.

Frequently asked questions

What is the Save Our Homes cap?
Once your home has a homestead exemption, Florida limits how much its assessed value can rise each year: 3 percent or the change in the Consumer Price Index, whichever is lower. Over time your assessed value falls below what the home is worth, and you pay taxes on the lower number. That gap is your Save Our Homes benefit.
Where do I find my just value and assessed value?
Both numbers are on the TRIM notice your county mails every August, and on your county property appraiser's website. Search for your address and look for 'just value' (also called market value) and 'assessed value.'
How much of my benefit can I take to a new Florida home?
Up to $500,000, if you abandon the old homestead and claim a new one within three tax years. If the new home costs as much or more than the old one, you can move the full benefit up to the cap. If you downsize, the amount shrinks in proportion to the new home's value.
Is this calculator exact?
No. It is an estimate. Tax rates vary by city and county, part of the homestead exemption does not apply to school taxes, and the second $25,000 of exemption adjusts with inflation. Your county property appraiser calculates the official numbers.
