At a Glance
- Select a goal type, set your target amount, current savings, months to goal, and savings rate, and the tool calculates the monthly saving needed to reach your target by your chosen date. The effective savings start figure combines your current savings and any lump sum you can add now, reducing the monthly saving requirement from the outset. How to use this tool
- The lump sum slider lets you model the impact of a one-off payment toward your goal, such as a bonus, a gift, or proceeds from selling something. Because the lump sum reduces the shortfall before the monthly calculation runs, even a modest one-off contribution can meaningfully reduce either the required monthly saving or the time needed to reach the target.

- The save faster panel shows how saving £50 or £100 more per month would reduce the time needed to reach your target. This is a passive display, meaning it updates automatically as you adjust your inputs, so you can see at a glance whether a small increase in monthly saving would bring the target date significantly closer. Setting a realistic goal timeline
- If the numbers show that saving alone cannot close the gap within your chosen timeline, a separate panel appears showing the projected balance at your deadline, the remaining shortfall, and a link to check eligibility for a loan to bridge the difference. This panel only appears when the maths makes it relevant, and it shows the shortfall honestly rather than suggesting borrowing is the default answer. When saving alone will not close the gap in time
- The target date display updates automatically as you adjust the months slider, showing the goal month and year so you can connect the abstract timeline to a specific point on the calendar. This makes it easier to test whether the timeline is genuinely fixed or whether it has flexibility that could reduce the monthly saving pressure. Frequently asked questions

About this tool
What it calculates
Monthly saving needed to reach a goal by a chosen date
Choose a goal type, set your target amount, current savings, any lump sum, your timeline in months, and a savings rate. The tool uses the standard annuity formula to calculate the monthly saving needed, applies compound interest month by month, and plots the balance against the target on a line chart so you can see the trajectory toward the goal date.
Key features
Lump sum slider, save faster panel, and borrow the gap option
The lump sum slider models a one-off payment added at the start, reducing the running shortfall immediately. The save faster panel passively shows how adding £50 or £100 per month would compress the timeline. If saving alone cannot close the gap within the chosen period, a separate panel shows the projected shortfall at the deadline and the option to check borrowing eligibility for the remaining amount.
How to use the savings goal planner
The tool works best when you enter figures that reflect your actual situation rather than aspirational ones. A realistic monthly saving amount and an honest assessment of what the goal actually costs produce a more useful result than optimistic inputs.
Choose your goal type and set the target amount
Select the goal category that best matches your objective: holiday, car, house deposit, wedding, home improvement, or other. The category updates the label on the results display so the output is framed around your specific goal. Set the target amount as the full cost of the goal, including any associated expenses you would need to cover at the same time. For a car, for example, the target might include insurance, road tax, and first service costs alongside the purchase price.
Enter current savings and any lump sum
If you already have money set aside for this goal, enter the current balance. The lump sum slider lets you add a separate one-off amount that you can put toward the goal immediately, such as a bonus, a tax refund, or money from selling something. The tool combines these into a single effective starting figure and calculates the remaining gap that monthly saving needs to cover, so the monthly requirement reflects what you actually still need to save rather than the full target.
Set your timeline and savings rate
Use the months slider to set how long you have to reach the goal. The target date display updates automatically to show the calendar month and year, which helps test whether the deadline is genuinely fixed or whether it has some flexibility. The savings rate reflects the AER on the account where the money will sit. Using the current rate on your chosen easy-access account produces a more accurate projection than a generic figure, since interest on the growing balance contributes to reaching the target slightly sooner.
Review the save faster panel and the borrow the gap option
The save faster panel shows how much sooner you would reach the target if you saved £50 or £100 more each month. This updates automatically as you adjust the main inputs, so you can see whether a modest increase in saving has a large or small effect on the timeline for your specific goal. If the tool calculates that your current saving rate cannot reach the target within the chosen period, a separate panel appears showing the projected balance at the deadline, the remaining gap, and a link to check borrowing eligibility for that amount.
Setting a realistic goal timeline
The monthly saving requirement is directly determined by three variables: the gap between current savings and the target, the savings rate, and the number of months available. Of these, the timeline is often the one with the most flexibility, and adjusting it by even a few months can meaningfully change the monthly figure. A target that requires £400 per month over 18 months might only require £280 per month over 24 months, and the question of whether the goal genuinely must be achieved in 18 months is worth examining before accepting a higher monthly commitment.
The distinction between a hard deadline and a soft preference matters. Some goals have fixed dates: a wedding with a venue deposit due by a specific month, or a car needed to start a new job. Others are genuinely flexible even if they feel urgent. Testing a few different timelines in the tool, using the months slider, makes this visible in concrete monthly saving terms. If extending the timeline by six months reduces the monthly saving by a meaningful amount without creating a real problem, extending the timeline is the simpler solution. If the deadline is genuinely fixed and the required monthly saving is higher than the budget allows, the tool will show the gap that borrowing would need to bridge.
How a lump sum changes the calculation
A lump sum contribution at the start of the saving period has a larger effect on the monthly saving requirement than the same total amount saved gradually over the term. This is because a lump sum added immediately begins earning interest for the full remaining period, while contributions made gradually only earn interest from the point they are added. The tool models this directly: entering a lump sum on the slider reduces the effective starting gap, and the monthly saving figure recalculates around the smaller shortfall.
The lump sum slider is particularly useful for modelling a known one-off payment that is expected but not yet received, such as a year-end bonus, an inheritance, or the proceeds from a previous savings account that will mature within the goal period. Setting the slider to the expected amount shows what the monthly saving requirement would be once that payment is applied, which is a more accurate picture of the ongoing commitment than calculating without it. If the lump sum is uncertain in size or timing, it is worth running the calculation both with and without it to understand what the monthly saving needs to be in the event the payment does not arrive on schedule.
When saving alone will not close the gap in time
The tool is honest when the numbers do not work within the chosen timeline. If the monthly saving amount is insufficient to reach the target by the chosen date even at the current savings rate, the borrow the gap panel appears. It shows the projected balance at the deadline based on what saving alone would produce, and the remaining shortfall that would need to come from somewhere else. This is not a prompt to borrow; it is a factual statement of the gap between the saving plan and the target.
Whether borrowing is the right response to that gap depends on the specific goal, the cost of borrowing relative to the benefit of achieving the goal on the original timeline, and the affordability of both the monthly saving and any loan repayment running simultaneously. A holiday gap of a few hundred pounds might be easily closed by a short personal loan with a low total interest cost. A house deposit shortfall of several thousand pounds involves a different scale of decision with longer-term implications for mortgage affordability. The panel provides a link to check borrowing eligibility, but the decision about whether and how much to borrow is one that benefits from running the numbers on the full cost of any loan alongside the saving plan. The true daily cost of borrowing calculator is a useful companion for understanding what a bridging loan would actually cost before committing to it.

How does the tool calculate the monthly saving needed?
The tool uses the standard future value of annuity formula, which calculates the fixed monthly payment needed so that a series of equal contributions, with interest applied each month, reaches a target sum by the end of the period. The effective starting figure is your current savings plus any lump sum you have entered. The remaining gap between that figure and your target is what the monthly saving needs to close over the chosen term, accounting for the compound interest that builds on both the starting balance and each monthly contribution as it is added.
When the effective starting figure already meets or exceeds the target, the tool shows a goal-reached state: you do not need to save anything additional to hit the target, and the question becomes how to manage or protect the money you already have. This can happen when a lump sum is large relative to the target, or when existing savings are close to the goal amount.
What happens if I cannot save enough each month to reach my target in time?
If the monthly saving amount you enter cannot reach the target within the chosen timeline, the borrow the gap panel appears. It shows the projected balance at your deadline based on your current saving rate, and the remaining shortfall between that projection and your target. The panel includes a link to check eligibility for a loan to cover that shortfall, which only appears when the gap is mathematically real and has not been closed by saving alone.
Before considering borrowing, it is worth testing whether the gap can be closed by other means: extending the timeline slightly, adding a lump sum, increasing the monthly saving amount, or reducing the target figure slightly if there is flexibility in the goal cost. The save faster panel shows how much sooner you would reach the target if you increased monthly saving by £50 or £100, which may show that a small budget adjustment closes the gap entirely without any need to borrow. If borrowing is the chosen route, the true daily cost of borrowing calculator helps model what the loan would actually cost in interest over its term.
Should I include an expected lump sum I have not received yet?
It depends on how certain the lump sum is. If it is a confirmed payment, such as a maturity date on a fixed-rate bond or a redundancy payment that has already been agreed, it is reasonable to include it and build the saving plan around the lower gap it creates. If the lump sum is less certain, such as a bonus that depends on performance or an inheritance that is expected but not confirmed, it is worth modelling both scenarios: one with the lump sum and one without.
The reason to run both scenarios is that a saving plan built around an expected lump sum that does not materialise leaves you short at the deadline with less time to adjust. Modelling the no-lump-sum scenario shows the monthly saving you would need to maintain if the payment is delayed or reduced, which tells you whether the plan remains achievable without it. If it is not, the plan is essentially dependent on the lump sum, and it is worth knowing that explicitly before committing to it.
Can I plan for more than one goal at the same time?
The tool calculates one goal at a time. To plan for multiple simultaneous goals, run the tool separately for each one and add up the required monthly savings to see the combined commitment. If the combined figure exceeds the available monthly saving capacity, the priorities become clear: which goal has a fixed deadline, which is flexible, and which might be deferred or reduced in scope.
For a broader view of how multiple financial priorities fit within the overall budget, the monthly budget planner maps income against all spending categories, including savings, which can help identify whether the combined saving commitment for multiple goals is realistic given the full picture of income and fixed outgoings. Separating savings pots for different goals in different accounts is a widely used approach for keeping the goals distinct and tracking progress on each one independently.
Does the savings rate make a significant difference for shorter-term goals?
For goals with a short timeline, such as six to twelve months, the savings rate has a relatively small effect on the monthly saving required. The interest earned on a growing balance over six months at 4% AER is modest compared with the contribution amount, so the difference between a 3% and 5% savings rate on the required monthly saving is usually small. Over longer timelines, the compounding effect becomes more meaningful and the savings rate has a larger influence on the result.
The more significant practical point for shorter-term goals is accessibility. If the goal has a firm deadline, the savings account needs to allow withdrawals when needed rather than locking the money in for a fixed term. Easy-access accounts typically offer slightly lower rates than fixed-term products, but the flexibility is more important than the marginal rate difference for a goal with a known and immovable completion date. Entering the actual rate on your chosen easy-access account, rather than the best available fixed rate, produces a more accurate projection for this reason.
Squaring Up
The savings goal planner translates a financial target and a deadline into a concrete monthly saving commitment, accounting for what you already have saved, any lump sum you can put in upfront, and the interest the growing balance will earn along the way. The most useful thing the tool does is make the relationship between timeline, monthly saving, and target amount visible and adjustable, so that trade-offs between saving more, waiting longer, or accepting a smaller goal can be assessed in real numbers rather than approximate mental arithmetic.
When the maths shows that saving alone cannot close the gap within the chosen period, the tool is transparent about the shortfall. Whether borrowing to bridge that gap is appropriate depends on the goal, the cost of borrowing, and what the total combined commitment looks like. Running the true daily cost of borrowing calculator alongside this tool gives a clear picture of what any bridging loan would add to the overall cost of reaching the goal.
