Debt consolidation means combining multiple debts — credit cards, hire purchase, existing personal loans — into a single loan at (ideally) a lower interest rate. Done right, it simplifies repayments and reduces total interest. Done wrong, it extends your debt and costs more over the long term.
Consolidation works when: (1) the new loan rate is lower than your current average rate; (2) the loan term is shorter than or equal to your current longest debt; (3) you have the discipline not to run up new debt after consolidating. If you consolidate credit cards and then max them out again, you've made your situation worse.
How Debt Consolidation Works
- You apply for a personal loan large enough to cover all debts you want to consolidate
- On approval, funds are used to pay off your existing debts (credit cards, hire purchase, etc.)
- You make one monthly repayment to the new lender instead of multiple repayments
- If the new rate is lower, you pay less total interest — and you’re out of debt sooner or with lower monthly payments
When Consolidation Is Worth It
Typical scenario:
- $6,000 on a credit card at 20.95% p.a.
- $4,000 hire purchase at 24% p.a.
- $3,000 personal loan at 18% p.a.
- Total: $13,000 across 3 debts
Minimum monthly payments are stressful and interest accumulates across all three.
After consolidation:
- $13,000 personal loan at 11% p.a. over 4 years
- Monthly payment: ~$337 (single, predictable)
- Total interest: ~$3,192 vs. much more across the three debts at higher rates
The saving depends on the rate difference and how quickly you pay off the consolidated loan.
When Consolidation Is NOT a Good Idea
1. The new rate isn’t actually lower If your credit profile means you can only access a rate similar to or higher than your existing debts, consolidation doesn’t help. Run the numbers first.
2. You extend the term significantly Consolidating $20,000 of debt from a 2-year to a 7-year term lowers monthly payments but massively increases total interest — even at a lower rate.
3. You use it to fund a spending habit Consolidating and then re-accumulating credit card debt is one of the most common financial mistakes. If the underlying spending pattern hasn’t changed, consolidation is a temporary fix.
4. Secured consolidation using home equity Consolidating unsecured consumer debt into a mortgage (home equity loan) converts it to secured debt against your home. Yes, the rate is lower — but if you fall behind, you risk your home. This is appropriate for some but is a serious step.

The Consolidation Process
- List all debts: Amount, interest rate, minimum payment, remaining term
- Calculate your current total interest cost (ask each lender for remaining interest or use a loan calculator)
- Get consolidation quotes from 2–3 lenders using soft credit checks
- Calculate the new total cost (consolidation loan total repayable including fees)
- Compare: Is the total cost lower? What is the monthly saving?
- Apply and use funds specifically to close existing debts immediately
- Close or reduce credit card limits — a critical step to prevent re-accumulation
