Arkansas Mortgage Calculator (with Arkansas Property Taxes & Insurance)

Arkansas property tax works differently from a simple percentage of a home's sale price. Under Arkansas's Constitutional Amendment 79, county assessors set an "assessed value" equal to 20% of a property's appraised market value, and it is that reduced assessed value, not the full price, that the local millage rate is applied against. Amendment 79 also caps how fast the assessed value of an owner-occupied homestead can increase each year, generally 5% annually, which shelters long-time Arkansas homeowners from sudden tax spikes even in a fast-appreciating market. This calculator models a 0.62% effective annual rate applied directly to the purchase price as a simplified planning baseline, since the true first-year assessed value and millage combination depends on the county and school district where the home sits.

Arkansas also offers a Homestead Property Tax Credit under the same Amendment 79 framework, which reduces the property tax bill on an owner-occupied primary residence by a set dollar amount each year regardless of the home's value. That credit is a flat reduction applied after millage calculation, and it is not reflected in this calculator's percentage-based estimate, meaning actual first-year bills for owner-occupants are often somewhat lower than what a flat 0.62% suggests.

This tool combines a standard 30-year fixed amortization for principal and interest with the modeled property tax rate and a flat homeowners insurance estimate to produce a single PITI figure, useful for an initial affordability check before a buyer requests a formal Loan Estimate from an Arkansas-licensed lender.

1. Down payment and loan principal. Loan Principal = Home Price x (1 - Down Payment %).
2. Principal and interest. The loan principal amortizes over 360 months:

$$PMT = \frac{P \times i}{1 - (1+i)^{-360}}$$

where P is the loan principal and i is the monthly rate (APR / 12).

1. Property tax estimate. Monthly Property Tax = Home Price x 0.62% / 12, applied to the purchase price as a simplified stand-in for the assessed-value-times-millage calculation Arkansas counties actually use.
2. Insurance estimate. A flat $125/month is added as a homeowners insurance placeholder.
3. PITI total. Monthly PITI = Principal & Interest + Property Tax + Insurance.

Using the calculator's baseline inputs, which match its published test vector:

• Home Purchase Price: $380,000
• Down Payment: 20% ($76,000)
• Interest Rate (APR): 6.5%

Step by step: - Loan principal: $380,000 x 80% = $304,000.00 - Monthly rate: 6.5% / 12 = 0.541667% - Monthly principal & interest: $1,921.49 - Monthly property tax: $380,000 x 0.62% / 12 = $196.33 - Monthly insurance estimate: $125.00 - Total monthly payment (PITI): $1,921.49 + $196.33 + $125.00 = $2,242.82 - Total interest paid over 30 years: $387,735.24

If this buyer instead put down only 5% ($19,000), the loan principal would climb to $361,000, and the calculator's low-down-payment scenario toggle shows the principal-and-interest portion rising past $2,280/month, a useful comparison for buyers weighing an FHA or conventional low-down-payment path against a traditional 20% down purchase.

• Amendment 79's 20% assessment ratio. Arkansas taxes 20% of appraised value, not the full sale price; a home's actual assessed value can differ meaningfully from a flat percentage of purchase price, especially soon after a sale when the assessor has not yet reappraised the property.
• The Homestead Property Tax Credit. Owner-occupants qualify for a flat annual dollar credit against their property tax bill; this calculator's percentage-based estimate does not subtract that credit, so actual bills for an owner-occupied home are often somewhat lower.
• County and school district millage variation. Millage rates differ across Arkansas's 75 counties and hundreds of school districts; 0.62% is a statewide effective-rate approximation, not a specific county's rate.
• Private mortgage insurance (PMI). Below 20% down, most conventional loans require PMI, which is not added separately in this calculator's low-down-payment scenarios.
• Closing costs and prepaid escrow reserves, which affect cash needed at closing but not the ongoing monthly payment shown here.

• Expecting a tax bill based on the full purchase price rather than the 20% assessed value Arkansas actually taxes, which can lead to over-budgeting for property tax if not corrected once an actual assessment is known.
• Forgetting to apply for the Homestead Credit after closing, which owner-occupants must generally file for with the county assessor to receive the reduction on future bills.
• Missing the 5% annual assessment cap when projecting long-term costs, which means a homestead's taxable value, and therefore its tax bill, typically rises more slowly than its market value in strong appreciation years.
• Skipping PMI in a low-down-payment scenario, which understates the true monthly obligation for any purchase financed above 80% loan-to-value.
• Not shopping insurance regionally, since flood and severe-weather risk (including tornado exposure) varies significantly across Arkansas and can push real premiums well above the flat $125/month placeholder used here.
