Savings goal calculator

Plans here compound a constant rate at a steady monthly cadence, which is a model, not a forecast: real returns wobble, fees and taxes come out of the rate, and deposits land when you actually make them. With inflation on, the goal is priced in future money while the return stays nominal, so the two are consistent but the plan says nothing about today's purchasing power of the interest. Monthly solving stops at 100 years; beyond that the honest answer is that the amount or the rate has to move.
