How much does mortgage interest actually save in taxes?

Only the portion of itemized deductions above the standard deduction ($29,200 married in 2024) generates actual tax savings. On $20,000 interest with $32,000 total itemized deductions in the 22% bracket: savings = (32,000 - 29,200) x 22% = $616.

Does everyone benefit from the mortgage interest deduction?

No. Most taxpayers take the standard deduction, making the mortgage interest deduction worthless for them. Only the approximately 13% of taxpayers who itemize actually benefit.

How does buying vs renting change when I factor in the tax benefit?

The deduction benefit is often overstated. In the first year on a $400,000 mortgage at 7%, you pay approximately $27,800 in interest. If your other itemized deductions total $10,000, you only benefit from $9,800 of deduction above the standard deduction threshold.
