Sinking Fund Setup
Create dedicated savings buckets for predictable future expenses such as repairs, travel, gifts, annual bills, and medical costs.
What Sinking Fund Setup gets you.
By the end of this upgrade you will have separate funded buckets for each predictable future expense, each with its own monthly contribution amount.
- List of predictable non-monthly expenses (car repairs, holidays, annual insurance, gifts, medical)
- Estimated cost and due date/timeframe for each
- A savings account that supports multiple sub-accounts or labeled buckets
- Current monthly budget with available discretionary room
Run the upgrade.
- 01
List every predictable irregular expense
Write down every expense that recurs but not monthly — car maintenance, holiday gifts, annual premiums, vet bills, home repairs — with an estimated annual cost for each.
- 02
Set a target amount and target date per fund
For each item, estimate the total amount needed and the date it's needed by (e.g., $1,200 for holiday gifts by December).
- 03
Calculate the required monthly contribution per fund
Divide each target amount by the number of months remaining until it's needed to get the monthly savings amount.
Monthly contribution = target amount / months until needed
- 04
Create separate labeled buckets or sub-accounts
Set up one labeled sub-account per sinking fund (many banks support this natively) so funds are not commingled and mentally spent elsewhere.
- 05
Automate a transfer into each bucket
Schedule a recurring automated transfer for each fund's monthly contribution amount right after payday.
- 06
Draw only from the matching bucket when the expense occurs
When the irregular expense hits, pay from its designated bucket only, then reset that fund's target for the next cycle.
- Every predictable irregular expense has a named fund with a target amount and date
- Each fund has a calculated monthly contribution
- Separate labeled buckets or sub-accounts exist for each fund
- Automated transfers are active for at least the largest funds
Monthly
- Confirm each automated transfer processed correctly
- Adjust target amounts annually as costs (insurance, gifts, etc.) change
- Add new funds as new predictable irregular expenses appear
