Budgeting for Life's Milestones, One Month at a Time
This article has been published as part of an advertising collaboration.
Some of life's bigger bills are not really surprises. Weddings, a new baby, replacing a car, moving home, and later-life costs can often be seen months or years in advance, even if you do not yet know the exact final figure.
That gives you the option to break a high future cost into smaller monthly amounts rather than paying the full amount when the bill arrives. A separate pot set aside for a known future expense is often called a sinking fund, and it differs from emergency savings because you already know what the money is being set aside for.
What is a sinking fund and when should you use one?
A sinking fund is a pot of money you pay into regularly for a cost you expect to face later. It can work for annual bills, weddings, holidays, school costs, car servicing, celebrations or preparing for a new baby.
The main benefit is that it turns one large number into something you can compare with your normal monthly budget. If you expect to need £1,200 in 12 months, the basic target is £100 a month; if you have two years, it falls to £50 a month.
That calculation also tells you when a goal is unrealistic. If the monthly amount would leave you short on normal bills, you can reduce the planned cost, give yourself more time, or save a smaller amount rather than forcing a target that does not fit your income.
How much should you save each month?
Start with the amount you expect to need, subtract anything already saved and divide the rest by the number of paydays before the deadline. The right figure is the one your normal budget can actually support rather than a fixed percentage somebody else says you should save.
For example, if you still need £2,400 towards a wedding and have 18 monthly paydays left, the basic target is about £133.34 a month. If that figure means relying on a credit card for food or bills later in the month, the goal needs to be adjusted.
Your target does not need to remain fixed forever either. A pay rise might let you increase it, while a temporary reduction in income could mean lowering the amount and extending the deadline.
What is the difference between a sinking fund and an emergency fund?
A sinking fund is for a cost you know is coming. An emergency fund is there for unexpected expenses, such as a loss of income or an urgent repair.
An annual car service belongs in a sinking fund because you know roughly when it will happen. A sudden breakdown is different because you cannot reliably predict when the cost will arrive.
Keeping the two pots separate stops a planned purchase from using up money that was supposed to protect you when something goes wrong. It also makes it easier to see how much of your savings is genuinely available for each purpose.
Should you automate monthly savings?
A standing order shortly after payday can make saving easier because the transfer happens before the money gets absorbed into everyday spending. You are also less likely to forget it when the transfer is automatic.
You do not necessarily need a separate bank account for every goal. If your current bank or savings app allows labelled pots, that can be enough to keep wedding money, annual bills and emergency savings visibly separate.
The important part is that the amount remains affordable. An automatic transfer that regularly leaves you short is not helping, so review it if your income or essential costs change.
Should you add a buffer to your savings target?
Future costs can change before you reach the deadline, especially when you are planning several months or years. Prices may rise, and smaller extras can appear that were not included in your original estimate.
MoneyHelper suggests allowing an extra 10% when estimating sinking-fund costs to give yourself some room for price changes.
For a £1,000 target, that might mean aiming for £1,100 rather than stopping exactly at £1,000. The right buffer depends on how uncertain the final cost is, but building in some room can be useful for expenses such as weddings and house moves where small charges quickly add up.
My guides to planning a wedding on a budget and how much a wedding costs can help break one of those larger milestones into individual costs.
How should you plan for funeral costs?
Funeral costs can be prepared for in several different ways. Some people keep money in accessible savings, while others consider insurance or a prepaid funeral plan that covers specified services in advance.
A prepaid funeral plan is not the same as keeping money in a savings account. It is a regulated financial product under which you pre-arrange and pre-pay for specified funeral services, either upfront or through instalments. The FCA has regulated the sector since the 29th of July 2022.
Funerals With Grace offers prepaid funeral plans that can be paid in full or spread over monthly instalments. The business trades through Plan with Grace Limited, which states that it is authorised and regulated by the Financial Conduct Authority under reference number 961832.
The monthly figure is not the only number to compare. Its current terms allow payment over 12 to 24 months without an instalment charge, while plans spread over three to five years carry a 6.5% instalment charge, so extending the payment period changes the total amount paid.
Check exactly what any funeral plan includes and excludes before buying. Flowers, catering and other extras may sit outside the plan, depending on the product, so the headline price is not automatically the full eventual cost of every funeral choice.
My guide to understanding funeral costs looks at the broader expenses that can arise, which can help you decide whether ordinary savings, a prepaid plan, or another arrangement fits what you want.
What if you cannot afford the monthly target?
Lowering the target is usually more useful than repeatedly missing it. Go back to the final amount and ask whether the cost can be reduced, the deadline extended, or part of the expense handled another way.
Expensive debt deserves attention too. If interest on borrowing is costing you more than your savings are earning, throwing every spare pound into a long-term savings target may not be the best use of the money.
For a non-essential goal, there is nothing wrong with taking longer. A monthly amount that fits comfortably into your real budget is more useful than an ambitious target that leaves you short before payday.
How often should you review a savings goal?
Check the target when either the cost or your finances change. You do not need to recalculate it every week, but reviewing it every few months can show whether you are ahead, behind or saving more than the goal now needs.
Plans change too. A wedding might become smaller, a house move may be delayed, or replacing a car could suddenly become more urgent.
Once one goal is complete, consider redirecting the same standing order towards the next planned expense. That keeps the saving habit in place without asking the budget to find a new amount from scratch.
Saving for big expenses works best when the money has a clear job, and the target fits your normal finances. Pick the next known cost on your calendar, work backwards from the deadline and start with a monthly amount you can maintain without making the rest of the budget harder to manage.
Frequently Asked Questions
What is a sinking fund?
A sinking fund is money you regularly put aside for a known future expense. Examples include weddings, annual bills, holidays, school costs, car expenses or saving for a new baby.
How do I work out how much to save each month?
Subtract any money you have already saved from the total you expect to need, then divide the remainder by the number of paydays left. If that figure does not fit your budget, change the cost, deadline or monthly target.
Is a sinking fund the same as an emergency fund?
No. A sinking fund is for a cost you expect, while an emergency fund is for something unexpected such as loss of income or an urgent repair.
Should I save immediately after payday?
It can help. Setting up a standing order shortly after payday moves the money before it gets mixed into normal spending and removes the need to remember the transfer each month.
Are prepaid funeral plans regulated?
Yes. The Financial Conduct Authority has regulated prepaid funeral plans since the 29th of July 2022, and firms that provide or sell them need the appropriate authorisation.
Is a prepaid funeral plan the same as saving for a funeral?
No. A prepaid funeral plan is a regulated contract covering specified funeral services, while ordinary savings remain money you hold and can generally use for other purposes. Compare what a plan covers, its total cost and its payment terms before deciding.
