Formula and Assumptions
FV = PV x (1 + r)^n + PMT x ((1 + r)^n - 1) / r, with binary search for rate or periods.

This uses a savings-style sign convention where payment increases future value.

Rate and month solving are estimates because they require numeric search or logarithmic rearrangement.

Reference Upgrade
Built from the Calculator.net model, with added context.

Live validation and instant result updates instead of a submit-only workflow.

Multiple decision metrics are shown together, not only the primary answer.

Formula notes and assumptions are visible on the page so the math is easier to audit.

Reference Model

Modeled after the input style and primary output on Calculator.net's Finance Calculator.

The page keeps the math in one place and exposes the assumptions beside the result.

Default inputs: solveFor=fv, presentValue=10000, payment=250, futureValueInput=25000, annualRate=6, months=60
