College Planning Calculator

Why it matters
Major life events have major tax implications. The "marriage penalty" can cost couples thousands, while strategic planning can turn it into a bonus. Homeownership offers mortgage interest and property tax deductions that many first-time buyers overlook. College costs rise 5–7% annually — without a plan, families face staggering student debt.
These calculators replace guesswork with numbers based on official 2026 IRS brackets and deduction limits. Whether you're engaged, buying your first home, or saving for a child's education, you'll get actionable numbers — not vague advice.
Based on 2026 tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37% | Standard deduction: $16,100 (single) / $32,200 (married)
