How does a divorce typically reshape monthly finances?
Two main shifts. First, total household income usually drops on each side — one income covering one household instead of two incomes covering one household. Even if combined income is the same, fixed costs duplicate (two rents, two utility setups, two insurance policies) so per-side discretionary income usually drops 20-40%. Second, support payments redistribute cashflow. Child support is calculated by state formulas and typically covers basic needs for the kids; spousal support varies widely. The post-divorce budget needs to be built from scratch — using the pre-divorce budget as a starting point usually overstates affordability. Plan for 3-6 months of higher costs (legal fees, moving, new household setup) before the new baseline stabilizes. Most people overspend in the first 6 months post-separation and underestimate the long-term reduction in margin.
When should I start a separate budget?
As soon as separation is decided, even before legal filings. The legal process can take 6-18 months in most US states (some longer for contested cases), and during that period your finances are usually in a transitional state — sometimes still combined, sometimes split, sometimes operating from temporary court orders. Starting a personal budget early gives you data for negotiations: knowing your real monthly costs makes alimony and child support calculations more accurate. It also gives you a head start on the post-divorce baseline. Most family law attorneys recommend keeping detailed records of all expenses (especially anything related to children or shared property) from the moment separation begins. Cash Compass's CSV export can produce clean monthly summaries if your attorney needs them.
What should I track during and after divorce?
Eight categories matter most. Housing for the new arrangement (rent or mortgage, utilities, insurance — usually higher per-person than pre-divorce). Legal fees if still ongoing (track these as a separate sinking fund). Child-related expenses if you have kids (schooling, activities, healthcare, clothing, agreed-upon shared costs). Support payments in or out. Insurance changes (health insurance especially — losing spousal coverage is a major shift). Retirement account changes (QDRO transfers, beneficiary updates, contribution adjustments). New solo expenses you didn't previously pay (the partner's car insurance, gym membership, phone bill, etc., now yours). And a 'transition costs' category for moving, furnishing a new place, replacing items that stayed at the old residence.
How do we split shared expenses fairly?
Most workable splits use one of three approaches. Proportional to income — if you earn 60% of combined income, you cover 60% of shared kid expenses. This is the formula many state child support calculators use. Equal split — each parent covers 50% of shared expenses, regardless of income. This is simpler but creates strain if incomes differ significantly. Category-based — one parent handles specific categories (school costs), the other handles different ones (medical), and they true up at year-end. Whatever split you choose, document it in writing and track in Cash Compass. The biggest source of post-divorce conflict around money is ambiguity: 'who pays for X?' Specific categories with logged transactions remove the ambiguity. CSV export lets you produce monthly statements if needed for ongoing court matters.
