Annual Bill Calendar & Expense Planner

The bills that don’t come monthly are the ones that wreck budgets

A monthly bill is easy — it’s the same number every month, so it’s already baked into how you think about money. The bills that hurt are the lumpy ones: the car insurance that bills every six months, the property tax that lands twice a year, the registration that shows up on your birthday month, the annual renewals that all seem to cluster, and the December gift spike. Each one is predictable on its own. Together they ambush you, because nobody’s tracking the month where three of them happen to collide. This planner exists to make that collision visible before it empties your account.

What the planner does

You list each irregular bill — what it costs, how often it hits, and which month it falls due. The tool spreads every bill across the year, totals each month, and does three things: it draws a 12-month calendar so you can see the shape of your year, it flags your worst month (the one that spikes), and it works out the single monthly amount to set aside so none of those months can blindside you.

The number that fixes it: your even monthly set-aside

The fix for lumpy bills is boringly simple: add up everything you’ll pay all year, divide by twelve, and move that slice into a separate account every month. By the time a heavy bill arrives, the money is already waiting. That’s the headline figure at the top of your result. It turns a stressful “how am I paying for this?” into a quiet transfer from savings you already made. The trick that makes it stick is the separate account — if the set-aside sits in your spending account, a good month will quietly absorb it.

A worked example

Say you carry $600 car insurance billed twice a year (March and September), a $1,200 property-tax bill in April, $80 registration in July, and you set aside $500 for the holidays in December. That’s $2,980 a year. Spread evenly that’s about $248 a month — but your calendar shows the real story: April is your worst month at $1,200, with March and September close behind. Budget the $248 average and April still hurts. Pre-fund it with the set-aside and April becomes a non-event.

Make it yours — save, print, export

Your list is saved in this browser, so you can come back and tweak it as bills change. When it’s right, you have two ways to take it with you: Print / Save as PDF gives you a clean one-page calendar to pin up or file, and Download calendar (.ics) drops an all-day reminder for each bill straight into Google Calendar, Apple Calendar or Outlook. None of it leaves your device unless you choose to export it.

What to put in it

If you own a home or a car, start with these — they’re the usual suspects behind a brutal month:

• Insurance — auto, home or renters, often billed every 6 or 12 months.
• Property tax — frequently split into two installments.
• Vehicle registration / tags and any emissions or inspection fees.
• HOA or condo dues, often quarterly.
• Annual renewals — warranties, memberships, domains, software, professional licenses.
• Seasonal spikes — holidays, back-to-school, birthdays you can see coming.

Assumptions and limitations

• It plans, it doesn’t predict. The numbers are whatever you enter. A premium that rises or a surprise repair won’t be in here until you add it.
• Monthly cycles only. Frequencies are monthly, quarterly, twice-a-year, yearly and one-off. For weekly costs, convert to a monthly figure first.
• The set-aside assumes you start early enough. If your worst month is next month, dividing by twelve won’t conjure the cash in time — it’s a plan for the year ahead, not a rescue for tomorrow.
• Pre-tax, single household. It’s a cash-flow planner, not a tax or net-worth tool.
