How do we budget on one income when the percentages don't add up?
Standard rules like 50/30/20 (50% needs, 30% wants, 20% savings) often don't fit one-income families because the needs portion runs higher. The 2024 Pew Research single-earner household data showed median spending of about 56% on needs (housing, food, transportation, insurance, healthcare), 27% on wants, and 17% on savings — a meaningful drift from the textbook ratios. Don't fight the textbook; just be realistic about your actual ratios. Build the budget from last 60 days of real spending in Cash Compass, identify the categories that are inflexible (housing, insurance, debt minimums), and decide what's adjustable (groceries, subscriptions, kids' activities). Track unassigned cash by week — that's the early-warning number.
My partner makes the money. How do we set this up fairly?
Apple Family Sharing covers both partners on one premium subscription. Both download Cash Compass on their own iPhones and sign in with their own Apple IDs. Decide which categories are shared (rent/mortgage, utilities, groceries, kids, insurance) and which are personal (each partner's own discretionary). Many SAHM households allocate the working partner a personal allowance category too, so both partners feel the same friction on personal spending. The 2024 American Time Use Survey showed primary-caregiver parents spend roughly 25 hours/week on direct childcare and household management — pricing that as unpaid labor at the prevailing childcare rate of $22/hour means it's worth about $28,500/year. Family financial visibility usually works better when both partners see and respect that math.
What about saving for kids' college on one income?
Create a Savings: 529 category and contribute monthly. The 2024 College Board put average annual tuition + fees at $11,260 for in-state public four-year and $41,540 for private — so an 18-year savings runway makes more headroom than starting at age 5. The honest math: if you can save $200/month per child from birth at 6% annual growth, you'll have about $75,000 by age 18, which covers most in-state public costs. Cash Compass tracks the monthly contribution; the actual 529 lives at Fidelity, Vanguard, or a state plan. Many states give a state income tax deduction for 529 contributions — worth $200-$1,000/year depending on state. Prioritize emergency fund first (3-6 months expenses), then employer retirement match if any, then college savings.
I want to start a side hustle. Can Cash Compass track that too?
Yes. About 24% of stay-at-home parents earn some income from side work according to the 2024 Pew Research survey — Etsy, freelance writing, tutoring, virtual assistant work, photography. Cash Compass tracks side-hustle income as a separate income category and side-hustle expenses (materials, software, web hosting, marketing) as their own expense categories. The CSV export at year-end separates the Schedule C income/expenses for tax purposes. The 2024 IRS data showed about 9% of jointly-filed returns included a spouse's Schedule C with revenue under $20,000 — Cash Compass plus a yearly tax-prep handoff is usually enough at that scale. Keep the personal and side-hustle expenses cleanly tagged so the year-end math doesn't require an archaeology project.
