How the calculations work

Runway: current available emergency savings divided by your monthly essential expenses. It is a simple average-month estimate, not a prediction of when a bank account will run dry. The what-if calculation first subtracts an emergency bill, then divides any remaining savings by the modeled monthly shortfall. If fallback income fully covers modeled costs, no monthly drawdown is projected; that does not mean your money is unlimited.

Goals and timelines: selected number of months multiplied by entered essential monthly costs. Savings are projected with a fixed end-of-month contribution and, if entered, a constant hypothetical APY converted to an effective monthly rate. Interest is estimated before tax; actual yields can vary. Timelines stop at 50 years rather than promising an impossible payoff.
