Debt is part of many people’s financial lives. Mortgages, personal loans, student finance and consumer credit make it possible to access goods or services before having all the necessary capital.
Problems arise when the cost of these obligations leaves too little room to save, invest or deal with unexpected expenses. Managing debt effectively does not necessarily mean paying it all off as quickly as possible, but rather understanding how much it costs, what risks it creates and which decisions can reduce its impact without compromising liquidity.
Start by understanding the true cost of each debt
Before deciding which debt to repay early, it is worth getting a complete picture.
For each debt, gather at least the following information:
- Outstanding balance.
- Monthly repayment.
- Remaining term.
- Fixed or variable interest rate.
- Annual percentage rate (APR) or effective cost.
- Any early repayment fees.
The monthly repayment alone tells you little. Two loans with similar monthly payments can have very different total costs.
It is also worth looking at the APR rather than just the nominal interest rate, as it makes it easier to compare different financing options.
The goal is to understand which debts cost the most and which would leave you most vulnerable if your income changed.
Before repaying debt, stop it from growing
Reducing debt achieves little if you continue taking on new borrowing to cover everyday expenses.
This is particularly important with certain deferred-payment credit cards or revolving credit facilities. When monthly repayments are very low, the principal may be paid down extremely slowly.
Before designing a repayment strategy, it is therefore important to check that your total outstanding debt has stopped increasing.
If your expenses regularly exceed your available income every month, paying off one particular debt will not, on its own, address the underlying cause. In that case, reviewing your spending habits may also help, as we explain in our article on how to avoid the trap of rising spending.
Prioritise the most expensive debts, without overlooking risk
A common strategy is to direct any surplus money towards the debt with the highest cost while keeping up with the minimum payments on all other debts.
Known as the debt avalanche method, this approach generally reduces total interest costs more efficiently.
Another option is to pay off debts with the smallest outstanding balances first, gradually eliminating individual obligations. This can be more motivating, although it does not always minimise financial costs.
In any case, a small debt with a very high APR may deserve greater priority than a larger but significantly cheaper loan.
A lower monthly payment does not always mean a better deal
Refinancing or consolidating debts can be useful when you have several financial obligations or when monthly repayments have become difficult to manage.
However, it is important to distinguish between reducing the monthly payment and reducing the total cost.
Extending the term of a loan may improve monthly liquidity while also increasing the number of years over which interest is paid.
Before accepting a refinancing offer, compare the remaining cost of your existing debt with the cost of the new financing, including fees, repayment term and any additional security requirements.
The question is not just how much the monthly payment falls, but how much you will ultimately pay.
Do not repay so much debt that you run out of liquidity
Paying off debt saves money on interest, but it also uses up cash.
Using all your savings to repay a relatively low-cost loan can leave your household without enough money to cover an unexpected repair, a temporary loss of income or another unforeseen expense.
Debt reduction should therefore go hand in hand with maintaining an adequate cash buffer. Its purpose is to prevent unexpected expenses from forcing you to borrow again.
Should you repay debt or invest?
Once your most expensive debts are under control, another question may arise: should you continue making early repayments or use your surplus money to invest?
The comparison should go beyond the interest rate on the debt versus the expected return from an investment.
Repaying debt produces relatively predictable interest savings. Investment returns, on the other hand, are uncertain and may involve losses.
Liquidity, taxation, investment horizon and your ability to withstand fluctuations also matter.
That is why manageable, low-cost debt can coexist with an investment strategy. In our article on whether it is better to repay debt or invest, we explore this dilemma in greater detail.
Monitor how much of your income is committed to debt
There is no single appropriate level of debt for everyone.
What matters is checking what proportion of your net income goes towards debt repayments and how much remains for essential expenses, savings and unexpected costs.
One simple question can help:
Would I still be able to meet my debt repayments if my income temporarily fell or a major expense arose?
The smaller that financial margin, the greater your vulnerability.
This review forms part of a broader assessment of your financial health.
The purpose of borrowing matters too
Borrowing to fund everyday consumption is not the same as borrowing to finance a home, a business or an investment.
Debt linked to an asset may have a different economic rationale, but it is not risk-free either. Borrowing to invest creates a definite obligation — repaying the loan — to finance an uncertain outcome.
That is why it is particularly important to assess your repayment capacity, financing costs and what would happen if the investment performed worse than expected.

When optimisation is no longer enough
Certain warning signs suggest that the problem is no longer simply deciding which debt to repay first:
- Taking out one loan to repay another.
- Repeatedly falling behind on repayments.
- Seeing your total outstanding debt continue to rise.
- Continually relying on credit for essential expenses.
- Being unable to meet repayments without sacrificing basic needs.
In these situations, it is advisable to act as soon as possible and consider negotiating with creditors or seeking professional advice.
Managing debt effectively means maintaining financial balance
The relevant question is not whether having debt is good or bad, but whether its cost, purpose and level are compatible with your income, liquidity and financial goals.
Good debt management means tackling the most harmful obligations first, comparing total costs before refinancing and preserving a financial buffer for unexpected events.
When debt is under control, it leaves more room to save, invest and build long-term wealth.
