Peak Earnings
Dual-Income Dan & Dana
VP Finance & Senior Product Manager · New York, NY
Two high incomes, two 401(k)s, two opinions on money. Zero coordination.
About Dual-Income Dan & Dana
Dan literally runs financial strategy for a Fortune 500 company and Dana ships product for a living, yet they have never once sat down to optimize their own household. They have $45k earning 0.4% in a savings account, two uncoordinated 401(k)s making redundant tax bets, and a combined $320k income that they suspect is leaking tens of thousands a year in avoidable taxes. The irony is not lost on them — they are world-class professionals who cannot manage to coordinate a single Saturday about their own money.

Dan and Dana's $45k savings account earns $180/year at 0.4%. They model three deployment options: high-yield savings at 4.8%, a taxable brokerage with a 70/30 allocation, or paying down their $480k mortgage at 5.9%.
Uses: fireThe Mega Backdoor Roth

Uses: roth-vs-traditionalThe Coordination Problem
Dan and Dana map their combined finances for the first time. They discover they are both contributing to Traditional 401(k)s despite being in the 35% bracket, they have $45k sitting in a savings account earning 0.4%, and they have never run a backdoor Roth. The model shows the annual tax cost of their incoordination.
