Debt and Borrowing: A Smart Guide to Responsible Credit

When it comes to financial debt, two extreme views exist. The first: "Debt is bad. Avoid it at all costs." The second: "Why wait? Buy now, pay later." The truth? Neither is right, but both contain elements of truth.

In today's world, aiming for a completely debt-free life is simply unrealistic. The question is not whether you will use debt, but how you use it. This guide covers the most common sources of debt, their characteristics, costs, and the key considerations when choosing the right form of credit for you.

Why Do People Borrow Money?

The most obvious benefit of borrowing is that you can buy things or have experiences you otherwise could not afford right now: a trip, furniture, a car, a home. But there is always a price. You must repay the borrowed amount along with all associated interest and fees.

When comparing different credit sources, consider:

Credit limit: How much can you borrow? Accessibility: How easy is this debt to obtain? Cost of borrowing: What are the real terms (not always transparent)? Repayment schedule: When and how often do you need to pay? Extra benefits: Are there advantages to one form over another?

Credit Cards

Credit cards are issued by financial institutions and certain retailers. They allow you to pay for goods or services on the condition that you repay the issuer according to agreed terms. When you make a purchase, the issuer provides the funds immediately and then collects the payment from you.

Why people use them

Credit cards are generally easier to obtain than other forms of debt. They are widely accepted, often required for online purchases, and many cards work internationally. A common extra benefit is rewards: depending on the card, you can earn loyalty points redeemable for hotels, flights, and other goods.

Responsible use of your credit card builds your credit history. Regular payments, ideally paying the full balance every month, contribute positively to your credit score.

What to compare before applying

Different credit cards vary significantly. Compare annual interest rates, annual fees, and extra charges for cash withdrawals, foreign currency transactions, and balance transfers. Annual interest rates typically range between 15% and 20%, although cards with lower rates exist (often with annual fees) and cards with higher rates may offer other benefits.

The minimum payment trap

Understanding how interest accumulates is crucial. Normally there is an interest-free period of around 21 days after a purchase. If you see a "minimum amount due" on your statement, that is the minimum payable now, but your full balance is listed below it.

Warning: If you only pay the minimum amount, interest starts accumulating on transactions from the original purchase date. Not paying off your full balance each month can cost you hundreds of euros over a year.

Use the Credit Card Payoff Calculator to see exactly how much you save by paying more than the minimum, and when you will be debt-free.

Line of Credit

A line of credit is essentially a loan (usually from a bank) that lets you borrow up to a predetermined amount. It works similarly to an overdraft facility: you can withdraw cash, pay for purchases, transfer balances, and pay bills.

How interest works differently

Unlike credit cards, money drawn from a line of credit starts accumulating interest immediately and continues until it is fully repaid. If you have not used your credit line, the balance stays at zero with no interest or significant fees.

There are several types: personal, home equity, student, secured, and unsecured. The differences relate to credit limits, interest rates, and restrictions.

The real advantage

The main advantage over credit cards is that interest rates and fees are generally lower. For example: if you have a credit card balance of 1,000 euros accumulating 20% interest and you cannot pay it off within the interest-free period, you save money by transferring that balance to a line of credit at 9% interest.

Note: Because a line of credit has lower interest rates, people sometimes build up larger balances than they would on credit cards, making it harder to pay off. A solid financial plan for every major credit purchase is essential.

The Debt Payoff Calculator lets you compare the avalanche and snowball methods side by side and see which one saves you the most interest.

Long-Term Financing

For larger, more significant purchases, specific financing options exist that are tailored to the product you are buying. The risk for lenders is lower because the underlying asset serves as collateral: if you cannot pay, the lender can repossess it.

Think of furniture you repay in 48 equal instalments: you use it, but technically it only becomes yours after the final payment. The same concept applies to car loans and, most significantly, mortgages.

Mortgage: The Biggest Loan of Your Life

Buying a home almost certainly requires borrowing money. A mortgage is a debt instrument specific to real estate, where the property serves as collateral to secure the loan.

Before applying for a mortgage, it helps to know how much you can safely borrow. The Borrowing Capacity Calculator works this out based on your income and existing obligations.

Down payment

A minimum down payment is required, ranging from 5% to 20% depending on the purchase price. Ideally these funds come from savings. In the Netherlands, the National Mortgage Guarantee (NHG) offers protection for mortgages up to roughly 435,000 euros (2025), which typically results in a lower interest rate.

If your down payment is less than 20%, or if you are self-employed or have a limited credit history, you may need additional insurance. This provides the financial institution with extra protection against default.

Understanding your mortgage terms

Your total mortgage amount equals the purchase price minus your down payment, plus any insurance costs. You then choose a fixed-rate period, in the Netherlands often 10, 15, or 20 years.

The mortgage contract is locked in for the chosen rate period. Changes before it expires typically incur penalties. After the fixed period ends, you must agree on a new rate.

Amortisation: how your payments actually work

The amortisation period indicates how long it takes to fully repay the mortgage. Each payment contains both interest and principal repayment, but this is where things often surprise people:

If you have a mortgage of 300,000 euros and pay 1,500 euros per month, your balance barely drops in the early years. Payments at the start go mostly toward interest. As you approach the end of the term, more and more goes toward the principal. The total interest you pay over the full life of the mortgage can amount to tens of thousands of euros.

Use the Mortgage Calculator to compare monthly payments across different loan terms and interest rates.

Fixed vs. variable rate

With a fixed rate, your mortgage payments remain the same for the term, regardless of market changes. With a variable rate, your payments fluctuate with market interest rates. Variable rates are often lower initially, but if market rates rise, your payments rise too.
