ROSHI’s credit card repayment calculator helps estimate how long it will take to pay off existing balances and how much total interest will be paid based on different monthly payment amounts. Credit cards in Singapore charge interest rates of 25.9% to 29.9% p.a. on unpaid balances making them one of the most expensive forms of borrowing.

Our calculator shows the true cost of carrying a balance and demonstrates how increasing monthly payments dramatically reduces both payoff time and total interest. Understanding these numbers helps cardholders make informed decisions about repayment strategies, balance transfers or consolidating debt through lower interest options.

Quick Wedding Loan Facts

Credit card interest is charged daily on the outstanding balance at rates of 25.9% to 29.9% p.a. approximately 0.07% per day. Interest compounds meaning unpaid interest is added to the balance and incurs further interest. Paying only the minimum typically 1% to 3% of balance or $50 whichever is higher results in balances growing rather than shrinking.

Minimum payments are designed to keep balances outstanding as long as possible. On a $10,000 balance at 26% p.a., paying only the minimum $100 to $300 per month can take 15+ years to clear and cost $15,000+ in interest which is more than the original balance. 

Pay more than minimum even $100 extra per month dramatically reduces payoff time.

Balance transfer which means moving your debt to a 0% promotional rate card and clear it within the promo period.

Debt consolidation via a personal loan at 5% to 12% EIR to pay off 25.9% to 29.9% credit card debt reducing total interest.

If credit card debt will take more than 12 months to clear, a personal loan at 5% to 12% EIR is almost always cheaper than carrying a 25.9% to 29.9% credit card balance. For debt exceeding 12 times monthly income, a formal Debt Consolidation Plan (DCP) may be required.

Our Expert says

The Minimum Payment Is Not Your Friend

Credit card minimum payments are calculated to maximise interest revenue for the bank not to help you pay off debt. A $10,000 balance with minimum payments only can take over 15 years to clear, costing more than $15,000 in interest which means you'd pay more than double the original amount borrowed. 

When using our calculator compare minimum only payments against fixed higher amounts. Even increasing from $200 to $400 monthly can cut payoff time by 70% and save thousands in interest. Quote Icon

Icon A $10,000 balance cleared with minimum payments costs $8,800 in interest over 8 years. The same balance cleared at $600 per month costs only $1,400 in interest over 19 months which means $7,400 in total savings.

Icon All three options are significantly cheaper than the 25.9% to 29.9% credit card rate. Even a personal loan at 12% EIR. saves more than half the interest cost compared to carrying a credit card balance.

How to Use Our Credit Card Repayment Calculator (FAQs)

What balance should I enter?

Enter your current outstanding balance, the total amount owed including any unpaid interest already accumulated. Check your latest credit card statement for this figure.
Most Singapore credit cards charge 25.99% to 28.99% p.a. on unpaid balances. Check your card's terms or use 26% as a standard estimate.
Enter the amount you plan to pay each month. Run multiple scenarios, minimum payment, your current payment and a higher amount to see how each affects payoff time and total interest.
The calculator projects when the balance reaches zero based on fixed monthly payments minus daily compounding interest at the rate entered. Higher payments clear the balance faster and reduce total interest.
The calculator assumes no new charges are added to the balance. For accurate planning stop using the card while paying down existing debt or enter the projected balance including expected new charges.
Calculate each card separately or enter the combined balance at an average interest rate. For multiple cards, consider paying off the highest-rate card first which is called avalanche method or the smallest balance first also referred to as snowball method for psychological wins.
