Where the loan calculators elsewhere in this section work backward from a debt you already owe, these work forward from money you intend to set aside. The common thread is compounding running in your favour rather than against you: a balance that earns a return, has that return added to it, and then earns on the larger figure the next period — the same mechanism that makes debt expensive makes saving effective, just pointed the other way.

Two kinds of question show up repeatedly. Some calculators start from what you can set aside each month and project forward to a balance on a given date. Others start from a target — a deposit, a tax bill, a fixed amount by a fixed date — and solve backward for the monthly figure that gets there, which is a different calculation even though the same numbers are involved. An emergency fund is the exception to both: it is sized in months of essential spending rather than toward a fixed target, because its purpose is being available on short notice rather than growing toward a deadline.
None of this involves market risk the way the investment calculators elsewhere on this site do — the rates here are the fixed or near-fixed returns of savings accounts and cash deposits, not equity or bond markets.
