Year-End Money Review: Set Up Next Year's Budget

By Cedar & Ledger

The last week of December is a good time to look back at the year's money before you plan the next one. You don't need a perfect record. A rough look at what you planned, what you spent, and what surprised you is enough to make next year's budget more realistic.

Every dollar figure here is a made-up example to show the math, not a recommendation of what to spend or save. Use your own numbers. This is general information, not financial or tax advice.

Quick checklist

• ☐ Planned vs. actual by category
• ☐ List this year's surprises
• ☐ Check sinking funds + savings
• ☐ Start next year's holiday fund
• ☐ Simple Jan 1 budget reset

The steps below walk through each one.

Track the big picture month by month with a simple net worth spreadsheet.

Step 1: Gather what you already have

Set aside an hour and pull together:

• Bank and card statements (or the yearly summary many banks offer).
• Your budget or spreadsheet, if you kept one.
• A list of yearly and irregular bills: insurance, subscriptions, car registration, memberships.
• Your sinking fund or savings balances.

Don't try to categorize every transaction. You're looking for the big picture.

Step 2: Compare planned vs. actual by category

Pick your 6–10 biggest categories and write down what you planned and roughly what you spent.

Example (made-up numbers):

• Groceries: planned $4,800, spent about $5,400 (+$600)
• Eating out: planned $1,200, spent about $1,900 (+$700)
• Car repairs: planned $0, spent about $850 (+$850)
• Subscriptions: planned $300, spent about $420 (+$120)
• Holidays and gifts: planned $600, spent about $780 (+$180)

The point isn't guilt. Categories that ran over are where next year's plan was too low, or where you want to change a habit.

Step 3: List the surprises

Write down every cost that "came out of nowhere": a vet bill, a repair, a wedding trip, a yearly renewal you forgot. Most of these weren't really surprises. They were irregular costs. Each one is a candidate for a sinking fund next year.

Step 4: Check your sinking funds and savings

For each fund, note the balance now and what you used it for.

Example (made-up numbers): Car repair fund started at $200, you added $50 a month ($600), used $850, so you needed $50 from elsewhere. Next year, a slightly bigger monthly amount may fit better.

Also note your emergency fund and any debt balances compared with January, so you can see the direction you're moving.

Step 5: Start next year's holiday fund in January

If December felt tight, the easiest fix is time. Take this year's actual holiday spending, decide next year's total, and divide by the months or paychecks left.

Example (made-up numbers): $780 total ÷ 12 months = $65 a month, or $30 per paycheck if you're paid every two weeks (26 paychecks).

Starting in January makes each set-aside small. If the holidays are still ahead, How to Plan Holiday Spending and Still Cover January sets this year's total from what's left after January is covered.

Step 6: A simple January 1 budget reset

Use what you learned to set up next year:

1. Start from take-home pay, not salary.
2. Fix the categories that ran over by raising the plan, cutting back, or both.
3. Turn each "surprise" into a sinking fund with a monthly amount.
4. List yearly bills by month so you know when they hit.
5. Cancel what you don't use. The subscription list from Step 1 helps.
6. Pick one or two goals, like a bigger emergency fund or paying off one card, not ten.

Step 7: Schedule check-ins

A budget set in January drifts by March. Put a short monthly check-in on your calendar: 20 minutes to compare planned vs. actual and adjust.

A note on taxes

Year-end is also when people start gathering tax documents. This guide doesn't cover tax rules. If you have side income, deductions, or questions about what to keep, check official sources or a tax professional. If you usually get a refund, deciding now where it will go makes it easier to stick to; see What to Do With Your Tax Refund.

Common snags

• Trying to account for every dollar. Rough totals are enough to plan.
• Setting the same budget as last year. Use what actually happened.
• Too many goals. One or two get done; ten get forgotten.
• Waiting until February. Small set-asides only work if they start early.

A simple way to track it

You can do all of this on paper or in any spreadsheet. If you'd like a ready-made one, the Cedar & Ledger Sinking Funds Tracker helps you plan next year's funds per paycheck (details). (We make it, so take that into account.)
