United States Savings & Budget Calculators

Free, localized savings & budget planning tools updated for the 2026 financial year in United States.

Two very different savings questions live here. The inflation calculator shows what rising prices quietly do to cash, the real-return arithmetic that decides whether your savings are actually growing, in today's dollars, or just getting bigger numerals. The Trump Account calculator prices the OBBBA's new child accounts: a $1,000 federal seed for babies born 2025-2028, up to $5,000 a year of contributions locked and invested until 18, and the basis rules and FAFSA treatment that determine whether the account beats a 529 for your family.
