What are Today’s dollars vs. Future dollars vs. “at horizon”?

Today’s dollars answer: if money arrives later, what is it worth in today’s purchasing power? Inflation and waiting usually make future amounts “feel” smaller today, so a headline like “$1M at age 85” might read closer to ~$740k in today’s dollars under a simple illustrative inflation assumption. In scenario results, the Show dollars control is a viewing lens, not a new plan: Today’s dollars shows purchasing-power columns; Future dollars shows face-value amounts as projected; At retirement / At horizon pin that same future-dollar math to a life milestone (paycheck start age or planning-horizon end age). Lifetime scoreboard lines in today’s dollars also discount a stream of future amounts into today’s terms so years can be compared fairly.
