Owning a home comes with several financial benefits, and one of the most notable is the potential for tax deductions. The Mortgage Deduction Calculator helps homeowners estimate their tax savings by factoring in mortgage interest payments, property taxes, and their marginal tax rate.

While recent tax law changes have altered the standard deduction and limited certain benefits, many homeowners can still benefit from itemizing their deductions. This calculator provides a quick estimate of how much you might save on your taxes.

Example

Suppose you paid $8,000 in mortgage interest and $4,000 in property taxes this year. Your marginal tax rate is 24%.

• Total Deductible Amount = $8,000 + $4,000 = $12,000
• Estimated Tax Savings = $12,000 × 24% = $2,880

This means you may save approximately $2,880 on your taxes if you itemize deductions.
