Savings Goal Calculator

Understanding your result

The monthly amount fills the gap between your target and the modeled future value of money already saved. If that existing balance is sufficient under your assumptions, the required new contribution is zero.

To translate a purchase priced in today’s money into a future target, first use the Inflation Calculator with an inflation assumption appropriate to that expense.

The formula

T is the future target, P is existing savings, r is the annual percentage divided by 1,200, and n is the number of months. When the rate is zero, divide the unfunded amount by n. The schedule keeps full precision; displayed currency figures are rounded.

How to use this calculator

1. Enter the amount you want to have at the goal date.
2. Enter savings already assigned to that goal, excluding money reserved for other purposes.
3. Choose a time horizon and return assumption, then compare the monthly requirement with your budget.

Set the target in future money

If the goal is a purchase whose price may rise, increase today’s price for inflation before entering it here. A target of 1,000,000 in ten years is a nominal amount; the calculator does not automatically preserve today’s purchasing power.

Changing the deadline often has a large effect on the required payment. Compare shorter and longer horizons, and test a zero or lower return to see how dependent the plan is on growth. A projected return is uncertain, while the contributions are a cash commitment.

Assumptions & limitations

What this calculation assumes

• Existing savings remain invested throughout the period.
• New contributions are equal and occur monthly.
• No withdrawals, taxes, or account charges are deducted.

What to keep in mind

• The result is a mathematical funding estimate, not a recommended investment allocation.
• Rounded payments may leave a small final difference; review progress as balances change.
