Bonus, Refund or Inheritance: Apply a Lump Sum to Debt
Establish the net amount actually available, then rank the debts by cost and urgency before applying it.
In this article
When a significant sum arrives (bonus, refund, inheritance), contradictory advice pours in. It is best to fill in a spreadsheet in order. Start with the net amount: subtract taxes owed, if any, commitments made and pending bills before any allocation. A gross amount leads you to promise the same dollar twice. Next build the reserve, before the debts, up to a floor of two to three months of expenses. A payment that empties every pocket relocates the fragility instead of reducing it. Then rank the debts by cost and urgency, with a check almost nobody makes: each contract's prepayment privileges. A closed loan can limit payments or impose a penalty, while a card accepts anything. The costliest debt that takes the payment without fees gets the money first. This article structures the allocation line by line, with the traps of privilege-bound debts and the place of projects in the ranking.
Establish the net amount genuinely available
A bonus, a tax refund or an inheritance is not available at the amount announced. A bonus is taxable and often subject to insufficient withholding, which leaves a balance owing in the spring. An inheritance can involve estate costs or tax on transferred investments. A tax refund is net, but it often signals excessive withholding worth correcting going forward. The amount to allocate is therefore the balance after those obligations. Calculate it before spending, so you do not create one debt to pay off another.
Rank the debts by real cost
Rank the debts by interest rate, highest to lowest. This method minimizes total cost. A card at twenty percent comes before a line of credit at nine, which comes before a car loan at seven and a student loan at five. Some debts deserve a special place: a debt in collections, a tax arrear generating interest and penalties, an account threatening an essential service. Ordering by smallest balance, which clears the easiest debts first, costs more but sustains motivation. That is a real argument when several attempts have already failed.
Verify the penalties and the privileges
Early repayment is not always free. A fixed-rate personal loan can carry a compensation charge. A mortgage limits prepayments to an annual percentage before penalty. Some loans apply the payment to principal only on explicit request, and otherwise credit it against future payments. Check these rules with the lender before sending the money, then confirm on the next statement that the payment did reduce the principal. A misapplied payment produces the opposite of the intended effect: it advances the due dates without reducing interest.
Keep a reserve before paying it all down
If you put the entire sum toward repayment, you have no cushion left. The first surprise then brings the debt back through a credit card, often at a higher rate than the debt you repaid. A prudent allocation first keeps the equivalent of one to three months of essential expenses, then applies the rest to debts. It is also better to spread a large sum over time than to decide in a day. Holding part of it for two or three months, while the decisions settle, costs little and prevents regret.
Quebec scenario
The cheque from her uncle's estate arrives on a Tuesday: $18,500, the largest sum a hairdresser in Chandler has ever deposited at once. That same evening the advice pours in, all of it contradictory. She decides to listen only to her spreadsheet, filled in order. First the net amount. The inheritance is not taxable in her hands, but $1,200 in instalment catch-up and a dental bill already committed bring the real available sum down to $16,100. That figure goes at the top of the sheet, because allocating a gross amount leads to promising too much. Next the reserve, served before the debts. Her emergency fund covered three weeks of expenses. She adds $4,000 to reach two months, a floor she refuses to fall below again. A payment that empties every pocket only relocates the fragility. Last the debts, ranked by cost and urgency on three lines. The card at 20.99%, with a $6,300 balance, is paid off first and in full. The car loan at 8.9%, with a $9,100 balance, receives $5,800, after she checks a detail almost nobody checks: the prepayment privileges. Her contract allows partial payments without penalty. The student loan, with its favourable rate and tax credit, is deliberately spared and closes the ranking. By Thursday evening nothing is left, and every dollar is allocated in writing. The interest saved exceeds $1,900 in the first year. She says her next unexpected sum will find the spreadsheet already waiting.
