Module 6 · Lesson 1

Bills, Big Expenses & Sinking Funds

12 min read

The Problem

Rent hits on the 1st. The car insurance comes every six months. The paycheck lands on the 15th and the 30th. A budget that only knows monthly totals cannot tell you whether the 1st is going to hurt. And the twice-a-year bills? Those are the ones that "come out of nowhere" and land on a credit card.

Two tools fix this. Scheduled transactions tell the app when money moves. Sinking funds turn big irregular bills into small monthly ones.

Scheduled Transactions

A scheduled transaction is a bill, paycheck, or transfer that repeats on a known day. Rent on the 1st. Phone bill on the 12th. Paycheck twice a month. You create it once and the app knows it is coming.

That is what powers the cash-flow forecast you will use in Module 7. Without scheduled transactions, a forecast is just today's balance. With them, the app can show you what the balance looks like on the 28th, after rent and before payday.

Amounts follow the account's sign rules. On a checking account, a bill is negative and a paycheck is positive. On a credit card, a charge is positive and a payment is negative.

Try It: Schedule a Bill

  1. Navigate: Transactions → Scheduled
  2. Verify: demo data already lists recurring items such as Mortgage & Rent and Paycheck
  3. Click: "Create Scheduled Transaction"
  4. Type: Description — Internet
  5. Type: Amount — -79.99
  6. Select: Account — Primary Checking
  7. Select: Tag — Internet
  8. Select: Day of Month — 12
  9. Click: "Create"
  10. Navigate: Transactions → Scheduled
  11. Verify: Internet appears in the list for the 12th of each month

Scheduling a recurring bill

Set up every recurring item you listed in Module 2: each fixed bill, each minimum debt payment, each paycheck. Use exact amounts from your statements. When a bill changes, edit the scheduled transaction the same day. The forecast is only as good as this list.

Sinking Funds: Big Bills, Small Pieces

A sinking fund is money you set aside a little at a time for a bill you know is coming. Car insurance is $720 every six months? That is $120 a month. Budget $120 to an Auto Insurance line every month, and when the bill arrives the money is already there.

Same idea for anything big and irregular: property taxes, holiday gifts, a new set of tires, a vacation. Divide the total by the months until it is due. That is the monthly line.

In a zero-based budget, these lines look just like any other expense. So does saving. Your emergency fund, your vacation fund, and your extra debt payment are each a budget line with an amount. They are not "whatever is left." Nothing is ever left. That is the point.

Try It: Add a Sinking Fund Line

  1. Navigate: user menu → Settings → Tags
  2. Click: "New Tag"
  3. Type: Name — Auto Insurance Fund
  4. Select: Tag Group — Savings
  5. Click: "Save"
  6. Navigate: Budgets → List
  7. Click: your current budget
  8. Click: "Edit"
  9. Type: Auto Insurance Fund amount in Outflows — 120.00
  10. Type: one variable line in Outflows — lower it by 120.00 so the budget still nets to zero
  11. Verify: Net Cash Flow reads $0.00

Creating the sinking-fund category

A budget carries the lines it was created with. A category you add later shows up in the budget you create after it, so add sinking-fund categories before you plan the period they belong to.

Which Savings First

If money is tight, fund in this order:

  1. A starter emergency fund, so the next surprise does not go on a card.
  2. Extra payments on any debt over 15% interest.
  3. Sinking funds for the bills you already know are coming.
  4. Everything else: the trip, the down payment, the new couch.

One to three goals at a time. Spreading $200 across eight lines makes none of them happen.

Key Takeaway: Schedule every recurring bill and paycheck so the app knows when money moves. Turn big irregular bills into monthly sinking-fund lines. Savings is a line in the budget, never the leftovers.

Check Your Understanding

  1. What does a scheduled transaction do for you?

    Answer: It tells the app when a recurring bill, paycheck, or transfer happens, so the cash-flow forecast can show your balance on future dates.

  2. Your car insurance is $600 every six months. What is the sinking-fund line?

    Answer: $100 a month. Divide the total by the number of months until it is due.

  3. In a zero-based budget, where does savings come from?

    Answer: It is a budget line with its own amount, assigned like any other expense. It is never what is left over.

  4. On a checking account, what sign does a scheduled bill have? What about a paycheck?

    Answer: A bill is negative (money out). A paycheck is positive (money in).
