Mortgage Calculator Alabama
Alabama has the second-lowest property tax in the country, after only Hawaii — and a home's tax bill really depends on a form most owners never realize they need to file. This calculator shows both sides.

Understanding the Alabama mortgage market
What makes an Alabama mortgage different
Alabama's property tax is truly among the lowest in the country — but the homestead exemption that makes it so light isn't automatic, and skipping it leaves real savings unclaimed. This mortgage calculator Alabama buyers use assumes you've filed correctly.
Why Alabama's 10% assessment ratio matters so much
Alabama assesses owner-occupied residential property at just 10% of market value — a $240,000 home carries an assessed value of only $24,000, and it's that much smaller figure local millage rates are actually applied to. Non-owner-occupied residential property (rentals, second homes) is assessed at 15%, and commercial or industrial property at 20%. This structural split, combined with generally modest local millage rates across most of the state, gives Alabama an effective property tax rate around 0.37% to 0.40%, per the Alabama Department of Revenue — the second lowest of any US state, behind only Hawaii. This mortgage calculator Alabama tool reflects that starting point.
The H1 standard homestead exemption
On top of the 10% assessment ratio, any owner-occupant qualifies for the H1 homestead exemption, which removes up to $4,000 of assessed value from state property tax and up to $2,000 from county tax — regardless of age or income. Because Alabama taxes only 10% of value in the first place, this $4,000 exemption effectively shields the tax on the first $40,000 of a home's actual market value from state tax entirely. Like nearly every property tax benefit in Alabama, it must be claimed at the county revenue commissioner's office — it is truly not automatic just because you own and live in the home.
| Exemption tier | Who qualifies | Benefit |
|---|---|---|
| H1 (Regular) | Any owner-occupant, any age/income | $4,000 off state assessed value, $2,000 off county |
| H2 | 65+, adjusted gross income ≤ $12,000 | Full state exemption; county reduction on first $5,000 |
| H3 | 65+ with income ≤ $12,000 (federal), or totally/permanently disabled at any age | Full exemption from all state, county and school property tax |
| H4 | 65+, income above H2/H3 thresholds | Partial exemption, smaller than H2/H3 |
H2, H3 and H4 — the senior and disability tiers
Beyond the standard H1 exemption, Alabama offers escalating relief for qualifying seniors and disabled homeowners. H2 provides a full state tax exemption plus a county reduction on the first $5,000 of assessed value for homeowners 65 or older with limited income. H3 goes further, offering a full exemption from all state, county, and school property tax for qualifying seniors with sufficiently low income, or for anyone retired due to permanent and total disability regardless of age. H4 applies to seniors whose income exceeds the H2/H3 limits, still providing a partial benefit smaller than the fuller tiers below it. Each tier has its own documentation and, in several cases, annual revalidation requirements.
The January 1 assessment date rule
Alabama sets January 1 as the assessment date for each tax year, and your status on that specific date — age, disability, income — determines eligibility for that entire tax year. Turn 65 on March 15 of a given year, and you weren't 65 as of that January 1, so the senior exemption doesn't apply until the following tax year, even though you're clearly 65 for most of the current year. The one narrow exception is turning 65 or becoming disabled on January 1 itself, which does qualify for that year.
Current use valuation for agricultural land
Farms, timberland, and certain other qualifying land can be valued based on their actual current working use rather than speculative development value, which is often far higher, particularly near growing metro areas. This current use application must generally be filed with the county assessing official between October 1 and January 1 each year — a specific, easy-to-miss window worth knowing about for anyone purchasing agricultural or timber property in Alabama.
A worked example, start to finish. Say a buyer purchases a $240,000 home in Alabama as their primary residence and properly files the H1 homestead exemption. At the 10% assessment ratio, the assessed value is $24,000, reduced by the $4,000 state / $2,000 county exemption. At a typical combined effective rate of about 0.38% of the home's actual market value once all these mechanics are worked through, monthly property tax comes to roughly $76.
With a 10% down payment, this buyer finances $216,000 at 6.6% over 30 years, giving a principal and interest payment of about $1,378. Add typical Alabama insurance, and the full monthly payment comes to around $1,741 — truly one of the lowest property tax burdens of any state calculator on this site, driven almost entirely by the 10% assessment ratio doing most of the work before any exemption is even applied.
How to use this mortgage calculator Alabama tool
Enter the home price and down payment you're working with, along with your expected interest rate and loan term. The effective tax rate field defaults to a typical statewide figure of 0.38%, already reflecting the 10% assessment ratio and H1 exemption — adjust it if you know your specific county's actual combined rate. Add an estimated annual insurance premium, and this mortgage calculator Alabama shows your full estimated monthly payment.
Common mistakes to avoid
- Not filing the H1 homestead exemption after closing. It's truly not automatic, and skipping it leaves real savings unclaimed.
- Assuming a senior exemption applies the moment you turn 65. Eligibility is fixed to your status on January 1 each year.
- Forgetting some tiers need annual revalidation. H2 and H3 in particular often require signing off again each year.
- Missing the current use filing window. Agricultural and timber land applications generally run October 1 through January 1.
- Confusing the 10% owner-occupied ratio with the 15% non-owner rate. A rental or second home is assessed differently, not automatically at the favorable rate.
