What this demo shows. This demo runs the real Meridary engine on a sample household. It models U.S. federal income tax, a single flat state rate, your accounts, Social Security, RMDs, and Roth conversions — for a single-earner household. It does not model a house, mortgage, or other debt, a second earner, or Medicare IRMAA and ACA subsidy cliffs (those live in our free calculators). The sample figures are illustrative, and nothing you change here is saved.
