Combines compound growth on an initial deposit with the future value of a series of equal monthly contributions.
FV = P(1+r)^n + PMT × [((1+r)^n − 1) ÷ r]The initial lump sum grows exponentially based on the annual rate and compounding frequency.
FV_initial = Principal × (1 + r/n)^(n×t)The Savings Calculator applies industry-standard financial equations used by lenders, accountants, and planners. All intermediate values are computed with floating-point precision and rounded only for display.
