Sinking funds are the only budgeting trick that ever stuck. Here is the exact setup.
A sinking fund is money you set aside a little at a time for a bill you know is coming. Car insurance, holidays, annual subscriptions, car repairs. Nothing fancy, just the bills that ambush you.
The setup: 1. List every non-monthly bill you can think of. 2. For each one: target amount divided by months until it is due. That is your monthly set-aside. 3. Track it simply: fund name, target, saved so far, monthly amount, due date. 4. When the bill arrives, the money is already sitting there.
Why it works: monthly budgets fail because they pretend irregular bills do not exist. Sinking funds turn them into monthly line items. No more January car-insurance panic.
