Goal Savings Calculator

Three variables, pick two

A savings goal has a target amount, a deadline and a monthly contribution, and fixing any two determines the third. Most people fix the amount and the date and discover the required contribution is unrealistic. The productive response is to treat all three as adjustable: a target reached three months later at a manageable rate beats an aggressive plan abandoned in week six.

Interest matters less than you expect on short goals

Over one or two years, compound growth contributes very little. Saving for a deposit or a wedding is almost entirely about the contributions, which is why the account rate is a secondary concern and why the money belongs somewhere safe and accessible rather than invested. Over ten years or more the balance flips and growth does much of the work, which is when investment risk becomes worth taking.

Inflation erodes distant targets

A goal several years out is a moving target. A 30,000 deposit today needs roughly 34,800 in five years at 3 percent inflation to buy the same thing, and for a house deposit the relevant inflation is property price growth, which has often outpaced general inflation considerably. Setting a fixed nominal figure for a distant goal quietly guarantees a shortfall.

Automate it and treat it as a bill

A standing order on payday to a separate account outperforms intention reliably, because saving what is left at the end of the month means saving whatever survives. Keeping the money in a distinct account also prevents the balance being absorbed into everyday spending, which is the most common way a goal quietly fails.

Order of priority

Before a discretionary savings goal, clear high-interest debt: paying 20 percent on a credit card while earning 4 percent in savings is a guaranteed loss. Hold a small emergency buffer too, otherwise the first unexpected cost raids the goal and resets your progress.
