Savings Goal

Tell us the number and the deadline. We will tell you the monthly deposit that gets you there — or how close you will come.

How the math works.

Required Monthly = (G - C(1+r)ⁿ) × r / ((1+r)ⁿ - 1) Where: G = savings goal C = current savings r = monthly rate (annual ÷ 12) n = number of months If the result is 0, your current savings will exceed the goal.

The savings goal calculator inverts the annuity formula: instead of asking "what will I have?", it asks "what must I contribute to reach a specific target?"

If your current savings, grown at the expected rate, already exceed your goal, the required monthly contribution is zero. If the gap is large and the timeframe is short, the required contribution may be impractically high — a signal to either extend the timeline, increase the return (with more risk), or lower the goal.

For short horizons (under 3 years), use a conservative rate (1–4%, matching a high-yield savings account or CD). For longer horizons, a diversified portfolio may support higher assumptions, but with more variability.
