Savings Goal Planner
Work out the monthly amount needed to reach a target by a date.
A goal without a monthly number is a wish
"Save for a deposit" is not actionable. "Save 480 a month for 34 months" is, because it can be compared directly against a budget and either fits or does not. Working backwards from the target and the deadline forces that comparison immediately, and the usual outcome is discovering that one of the three variables — target, deadline, or contribution — has to move.
That discovery is the point. A plan that fails on paper in five minutes is much cheaper than one that fails in eighteen months when the deadline arrives and the balance is short.
On short horizons, returns barely matter
For a goal two or three years out, interest contributes a small fraction of the final balance — the contributions do nearly all the work. This has a practical consequence: money needed on a short, fixed timeline does not belong in volatile investments, because the potential upside is small relative to the risk of being down 20% in the month you need it. A savings account or short-dated deposit is the appropriate home, and the rate you get is a secondary concern.
Over ten years or more the calculation inverts and returns start to dominate, which is when the choice of vehicle genuinely matters.
Build the buffer into the plan, not around it
The most common reason a savings goal derails is not overspending — it is a single unexpected expense that empties the pot. If the emergency fund and the goal fund are the same money, every incident resets the plan. Keeping a separate buffer, even a small one, means a car repair costs you a month of progress instead of all of it.
It is also worth planning for the contribution to be missed occasionally. A schedule with no slack fails the first time a month is tight; adding 10% to the monthly target creates room for two missed months over a two-year plan.
How to use it
- Enter the target amount and anything you have already saved towards it.
- Enter the number of months until you need the money.
- Read the required monthly contribution and compare it against your actual budget.
- If it does not fit, extend the deadline or lower the target rather than assuming you will catch up later.
Before you rely on this
What if the monthly amount is unaffordable?
Extend the deadline, lower the target, or split the goal into stages. The calculation is designed to expose that trade-off early, while there is still time to act on it — not to tell you the goal is achievable when it is not.
Should I invest money saved for a short-term goal?
Generally no. On a horizon under about three years the expected return is small relative to the risk of a market fall in the month you need the money. A deposit account keeps the amount predictable, which is the property that actually matters here.
Should the emergency fund count towards the goal?
No. If the same money serves both purposes, any unexpected expense resets your progress entirely. Keeping even a modest separate buffer means an incident costs a month of saving rather than the whole plan.
How much slack should I build in?
Adding roughly 10% to the required monthly figure creates room to miss a month or two over a two-year plan without falling behind. A schedule with zero slack fails the first time a month is tight.
