Savings Goal Calculator

A savings goal is a specific amount of money you want to accumulate by a specific time — a house deposit, a wedding, a car, a holiday, or a starter emergency fund. The challenge most people face isn't wanting to save; it's knowing how much to save each month to actually arrive on time. This calculator solves that by reversing the usual savings math: instead of asking "how much will I have?", it asks "how much must I put in?".

The calculation has two parts. First, any money you've already saved keeps growing on its own, so the calculator projects what your existing balance will be worth at your goal date using your expected return. It then subtracts that from your target to find the gap your future contributions need to fill. Second, it works out the level monthly payment that, with compounding, grows into exactly that remaining amount — the future value of an annuity formula in reverse.

Three levers move the monthly number. A longer timeframe lowers the amount you need to save each month, because you have more months to contribute and more time for compounding to help. A higher expected return also lowers the monthly figure, since interest does more of the work — but be realistic: short-term goals should rely on safe, predictable returns from a high-yield savings account or CD rather than volatile investments that could fall right before you need the money. Finally, the more you've already saved, the smaller the gap that remains.

Used regularly, a savings goal calculator turns saving from a hopeful habit into a plan. If the required monthly amount is more than your budget allows, you can immediately see your options: extend the deadline, trim the target, or find room in your budget — all by adjusting a single input and watching the monthly number respond.
