SmartRetireCalc is a U.S.-focused retirement planning brand offering free online calculators, planning tools, and educational guides. Its central retirement calculator creates a year-by-year projection of income, withdrawals, taxes, and account balances, helping people explore how their choices may affect their financial outlook through retirement. The tools model pre-tax, Roth, and taxable brokerage accounts, Social Security benefits, required minimum distributions (RMDs), and federal taxes, including capital gains and Medicare IRMAA surcharges.

Users can compare Social Security claiming ages, identify potential Roth conversion windows, estimate sustainable spending, assess RMD-related tax effects, and test their plan against market downturns, high inflation, or longer lifespans. Additional features include an expense estimator, individual stock holdings with live price quotes, and sample scenarios for different retirement situations. People can begin without an account; creating a free account allows them to save and reload a plan. SmartRetireCalc presents its service as private, stating that user data is never sold and is not stored in the cloud unless a plan is saved.
