How to Create a Budget After Divorce in British Columbia
Start With What Actually Changed
Your pre-divorce household had two incomes (or one income covering two people). Now you're working from a fundamentally different financial base. A budget built on your married-life numbers is useless — the income changed, the expenses changed, and new categories exist that didn't before.
Pull three months of bank and credit card statements from before you separated, not to replicate that spending, but to identify which costs were shared and which are now entirely yours. Then build from the ground up.
Map Your New Income Sources
Your post-divorce income likely includes some combination of these:
Employment income. Your take-home pay after tax, CPP, and EI deductions. If you adjusted your TD1 forms with your employer after reporting your separation to the CRA, your withholding should already reflect your new marital status.
Spousal support received. If your ex-spouse pays you periodic spousal support under a separation agreement or court order, this is taxable income. Budget with the after-tax amount, not the gross — you'll owe tax on it at year-end if your employer isn't withholding on your behalf.
Child support received. Child support is not taxable income for the recipient. The full amount goes into your budget as received.
Government benefits. After you notify the CRA of your separation, your Canada Child Benefit, GST/HST credit, and BC Family Benefit recalculate based on your individual income. If you're the lower-earning custodial parent, these payments likely increased. Use the CRA's online benefits calculator to estimate your new amounts rather than waiting for the first adjusted payment.
Account for New Expenses You Didn't Have Before
These are the categories that catch people off guard in the first year:
Housing. If you moved out of the family home, your rent or mortgage is a new expense. If you kept the home and refinanced, your new mortgage payment may be higher than the joint one — you're carrying the full balance on one income.
Child care. If your ex-spouse previously handled school pickups or stayed home with the children, you may now need before- and after-school care, summer programs, or a nanny. Child care is deductible on your tax return (claimed by the lower-income parent, generally), which offsets some of the cost.
Insurance. If you were covered under your spouse's extended health plan, you now need your own. Individual health and dental coverage through Pacific Blue Cross, Sun Life, or another private insurer typically costs $150–$350 per month for a single adult. Auto insurance may also change if your ex-spouse was a listed driver on your Autoplan policy.
Legal fees still outstanding. If you're paying your lawyer in installments, include the monthly payment. Legal fees for establishing spousal support are tax-deductible for the recipient — but only in the year you pay them.

Build the Actual Budget
Use whatever format works for you — a spreadsheet, a budgeting app, or pen and paper. The categories that matter for a post-divorce budget:
| Category | Monthly Amount |
|---|---|
| Housing (rent/mortgage + property tax + insurance) | |
| Utilities (hydro, gas, internet, phone) | |
| Groceries | |
| Transportation (car payment, insurance, gas, transit) | |
| Child care | |
| Children's expenses (school, activities, medical co-pays) | |
| Health/dental insurance premiums | |
| Debt payments (credit cards, lines of credit, student loans) | |
| Spousal support paid (if applicable — this is deductible) | |
| Savings / emergency fund | |
| Personal (clothing, haircuts, subscriptions) |
Compare total expenses against total income. If expenses exceed income, the fix needs to happen now — not after you've accumulated credit card debt for six months.
The Two Traps to Avoid
Trap 1: Lifestyle inertia. Maintaining the same standard of living on half (or less) of the household income you had before. The family home, the car, the children's extracurriculars — keeping everything the same while your income dropped is the fastest path to unsustainable debt. Something has to adjust.
Trap 2: Ignoring the tax impact of spousal support. If you're paying spousal support, your actual cost is lower than the gross payment because it's tax-deductible. If you're receiving spousal support, your actual income from it is lower than the gross amount because it's taxable. Budget with the after-tax numbers for both sides, or you'll be surprised at tax time.
Build an Emergency Buffer
Divorce is expensive, and the first year after is financially volatile. Unexpected costs — a car repair, a child's medical expense, a legal bill — hit harder when your cash reserves are depleted from the divorce process itself.
Target three months of essential expenses in a savings account before you start any discretionary spending. If that's not realistic immediately, start with $1,000 and build from there. Automate a transfer on payday so it happens before you see the money in your chequing account.
