The Singles Tax
An itemized bill for your love life.
The big one, the living-alone premium, comes from Zillow's national analysis (about $7,000 a year) and StreetEasy's New York figure (about $20,000), scaled to your city size. Valentine's spend is the National Retail Federation's survey, the wedding footnote is The Knot's annual average, and the rest are the midpoints of the ranges you picked. Where a number is a guess, the receipt says so.
It takes what you spend each month, deposits it monthly into an account earning 5% a year compounded monthly, and runs that for ten years. It's the boring-index-fund counterfactual, not a promise about markets.
