How To Start Your First Sinking Fund
The idea of a sinking fund is simple. The execution is even simpler. But most people never start one because they're not sure where to begin — which fund to set up first, how much to put in, or how to track it.
This guide removes all of that uncertainty. Here's exactly how to start your first sinking fund, step by step.
Step 1: Choose One Expense To Start With
Don't try to set up six sinking funds at once. Start with one — the irregular expense that has caused you the most financial stress in the past.
For most people, that's one of these:
- Car maintenance and repairs
- Annual insurance renewal
- Christmas and seasonal costs
- Holiday or travel
- Home repairs
Pick the one that has caught you off guard most recently. That's your first sinking fund.
Step 2: Estimate The Total Cost
How much will this expense cost when it arrives? Be realistic — and slightly generous. It's better to have a little extra than to fall short.
Some examples:
- Car maintenance: €400–€800 per year depending on your car and age
- Annual car insurance: whatever your renewal quote typically is
- Christmas: add up gifts, food, travel, and any other seasonal costs
- Holiday: flights, accommodation, spending money, travel insurance
If you're not sure, look at what you spent last time. That's your baseline.
Step 3: Set A Target Date
When will you need the money? A specific month is enough — you don't need an exact date.
- Car insurance renewal: check your policy for the renewal month
- Christmas: November or December
- Holiday: the month you're travelling
- Car maintenance: spread across the year, or set a 6-month target for the next service
The target date tells you how many months you have to save.
Step 4: Calculate Your Monthly Contribution
This is the simple part. Divide the total cost by the number of months until you need it.
Example: Christmas costs €600. It's currently May — 7 months away. €600 ÷ 7 = €86 per month.
Example: Car insurance renewal is €480, due in 9 months. €480 ÷ 9 = €53 per month.
That's your monthly sinking fund contribution. Add it to your budget as a fixed line item.
Step 5: Set It Aside On Payday
On payday, move your sinking fund contribution before you spend anything else. This is the most important step. If you wait until the end of the month to move it, there may not be anything left to move.
Treat it like a bill — non-negotiable, paid first, every month.
Step 6: Track Your Progress
Once your sinking fund is running, track it. Know how much you've saved, how much is left, and whether you're on track to hit your target by the right date.
The Sinking Funds Tracker from VARDENCIA makes this automatic — enter your target, your contributions, and it calculates your progress, remaining balance, and required monthly amount for you.
When To Add More Sinking Funds
Once your first sinking fund is running smoothly — usually after 2–3 months — add another. Work through your irregular expenses one by one until the most significant ones are covered.
Most people find that 4–6 sinking funds covers the majority of their irregular expenses. How sinking funds work explains the full system in detail. If you don't have a monthly budget yet, the Monthly Budget Planner is the right starting point — sinking fund contributions work best as a planned line in a structured monthly budget.
Your first sinking fund doesn't need to be perfect. It needs to exist. Start with one expense, set aside the monthly amount, and track it. That's all it takes to stop being caught off guard.
