How these calculators work
Same engine discipline as the rest of AtFinance: exact-cent math, the 2026 federal brackets and standard deductions straight from IRS Rev. Proc. 2025-32, and market-rate defaults (Freddie Mac, Bankrate) that are dated — never “representative”. Every figure is an estimate for information, not financial advice.
