A tax deduction reduces your taxable income. The tax you save equals the deduction × your marginal rate. At 10%, every $1,000 deducted saves $100 in federal taxes.

Important: Marginal ≠ Effective Rate

Being in the 10% bracket does NOT mean you pay 10% on all income. You only pay 10% on the portion that falls within this bracket. Every dollar below $0 (single) is taxed at lower rates. Your effective rate is almost always much lower than your marginal rate.
