Tennessee Mortgage Calculator (with Tennessee Property Taxes & Insurance)

Tennessee combines two features that matter a great deal to homebuyers: no state income tax on wages, and a relatively low effective property tax rate. This calculator applies a 0.66% effective property tax rate, reflecting Tennessee's residential assessment ratio of 25% of appraised value applied against local county and municipal tax rates, which together tend to produce lower effective bills than many states with comparable home prices.

Because Tennessee fully repealed its Hall income tax on interest and dividends in 2021 and has never taxed wage income, homeowners here keep their full paycheck at the state level while also facing one of the lighter property tax burdens in this comparison set. That combination is a notable contrast with South Carolina, which pairs a low property tax rate with an active state income tax, and South Dakota, which has no income tax but a meaningfully higher property tax rate.

The mortgage payment math, principal and interest amortized over a 30-year fixed term, uses the same engine applied across every mortgage calculator on this platform. State-specific property tax rates and surrounding context are the only variables that change.

1. Down payment and loan principal. Down payment percentage is applied to the home price; the remainder becomes the loan principal.
2. Principal and interest (P&I). The loan principal is amortized over 360 months (30 years):

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

1. Property tax. Home price is multiplied by Tennessee's 0.66% effective rate and divided by 12 for a monthly figure.
2. Insurance. A flat $125 monthly homeowners insurance estimate is added.
3. Total PITI. Principal, interest, tax, and insurance are summed into the headline monthly payment.

Using the calculator's default inputs:

• Home Price: $380,000.00
• Down Payment: 20% ($76,000.00)
• Interest Rate: 6.5%
• Term: 360 months (30 years)

Step by step:

1. Loan principal: $380,000 − $76,000 = $304,000.00
2. Monthly principal and interest at 6.5% over 360 months: $1,921.48
3. Tennessee property tax: $380,000 × 0.66% = $2,508.00 per year, or $209.00 per month
4. Homeowners insurance estimate: $125.00 per month
5. Total monthly PITI: $1,921.48 + $209.00 + $125.00 = $2,255.48
6. Total interest paid over the full 30-year term: $1,921.48 × 360 − $304,000 = $387,732.80

• County and municipal rate variation. Tennessee's 95 counties, plus cities that levy their own municipal property tax on top of the county rate, produce a wide range of effective rates; 0.66% is a statewide approximation.
• The 25% residential assessment ratio mechanics. Only 25% of a home's appraised value is taxable in Tennessee, a different structure than states that tax closer to full market value; the 0.66% figure already reflects that ratio, but local mill rates still vary.
• Property tax relief for elderly, disabled, and veteran homeowners. Tennessee offers property tax relief programs for qualifying low-income elderly, disabled, and disabled veteran homeowners that can reduce the effective bill below this calculator's statewide estimate.
• PMI for down payments under 20%. This calculator does not add private mortgage insurance, typically required when the down payment is below 20%.
• HOA dues, flood insurance, or closing costs. None of these are modeled.
• Local sales tax impact on cost of living. Tennessee's 7% state sales tax plus local option tax (among the highest combined sales tax rates in the country) partially offsets the income tax and property tax savings modeled elsewhere on this platform, but is outside the scope of a mortgage payment calculator.

• Assuming a single statewide property tax rate applies everywhere in Tennessee. Nashville, Memphis, and smaller municipalities layer city property tax on top of county rates, which can push the effective rate meaningfully above or below the 0.66% statewide estimate depending on location.
• Forgetting that Tennessee's overall tax picture includes a high sales tax. No income tax and low property tax are real advantages, but Tennessee's combined state and local sales tax rate is among the highest in the country, which affects overall cost of living beyond the mortgage payment.
• Ignoring reassessment cycles. Tennessee counties reassess property values periodically (commonly every four to six years), which can change your tax bill independent of your mortgage rate.
• Overlooking the down payment threshold for PMI. Below 20% down, expect an additional PMI line item not reflected in this calculator's output.
• Not applying for available property tax relief. Eligible elderly, disabled, and veteran homeowners in Tennessee can significantly reduce their tax bill but must actively apply through their county trustee's office.
