The 20 systems
Household saving is organised the way money leaves a home: bills, food, transport, the kids, the big buys and the quiet digital drains. Each system is one cluster of guides, completed whole, from the foundations system where the household numbers are first written down to the calendar system that keeps the year on one page.
System 01 - Foundations system Saving foundations and the household money system Start here: how a household money system works, the one number that tells you it is working, and the small set of habits everything else on this site hangs from. (12 guides) System 02 - Audit system Subscription audits The full sweep: find every recurring charge, write down what each one really costs, and decide keep, cut or downgrade with a clear head. (12 guides) System 03 - Category system Subscriptions by category Streaming, apps, memberships, software, boxes and plans: what each category of subscription should be doing for your household, and the ones that quietly stop earning their place. (12 guides) System 04 - Heating and power system Energy bills Heating, hot water, cooling and the appliances in between: read your bill properly, then work the levers in the order they matter. (12 guides) System 05 - Services system Broadband, mobile and home service bills Speeds, data allowances, bundles and renewal windows: pay for the service your household actually uses, not the tier you were sold. (12 guides) System 06 - Renewal system Insurance renewal literacy Renewals are literacy, not advice: read the notice, compare like for like, understand deductibles and coverage, and never let a policy renew itself unnoticed. (12 guides) System 07 - Grocery system Grocery shopping systems Meal plans that happen, lists that run the shop, store layouts, bulk buying and the freezer: a grocery bill is a system problem, not a willpower problem. (12 guides) System 08 - Running costs system Household running costs The quiet budget: cleaning, laundry, water, pets, maintenance and the small consumables that leak money a few dollars at a time. (12 guides) System 09 - Transport system Transport costs Fuel, maintenance, passes, parking and the true cost per mile: spending less on getting around without giving up the car or the trips. (12 guides) System 10 - Family system Kids and family costs School costs, clothes, activities, parties and days out: family spending with a framework, so control does not mean saying no to everything. (12 guides) System 11 - Seasonal system Seasonal and annual costs The costs that arrive once a year and ambush the monthly budget: holidays, back to school, winter, summer and the annual renewals month. (12 guides) System 12 - Buying literacy system Buying literacy Unit prices, price cycles, cost per use and sales theatre: how to read a price calmly and decide like someone who is not being hurried. (12 guides) System 13 - Big purchase system Big purchases Appliances, furniture and electronics: total cost of ownership, repair or replace, warranties read properly, and the extras nobody quotes. (12 guides) System 14 - Automation system Savings automation Money that moves itself on payday: transfers, splits, round-ups and automated bills set up once, so saving does not depend on remembering. (12 guides) System 15 - Sinking fund system Sinking funds and savings goals Known future costs, funded monthly in advance: car repairs, home repairs, holidays, gifts and the annual bills that are only a surprise once. (12 guides) System 16 - Challenge system Savings challenges and money routines Challenges that teach something and routines that outlast them: the pantry challenge, the ten-minute money check, use-it-up months and selling one thing a week. (12 guides) System 17 - Waste system Avoiding waste Food in the bin, returns never made, duplicates in the cupboard and guarantees never claimed: the money your household already spent, recovered. (12 guides) System 18 - Repair system Second-hand and repair Buy it used, mend it first, keep it alive longer: what to buy second-hand, what to check, and the repair-or-replace question in the right order. (12 guides) System 19 - Digital hygiene system Digital spending hygiene Trials, taps and renewal traps: free-trial reminders, auto-renew sweeps, in-app purchases and the stored cards that make spending invisible. (12 guides) System 20 - Calendar system The annual money calendar The whole year on one page: the once-a-year review, the monthly money jobs, the records worth keeping, and the check that proves the system worked.
