Understanding the Total Debt Servicing Ratio (TDSR) and Its Impact on Your Loan Applications
20 May 2025 | Monetium Credit
The world of credits may appear to be confusing at first, but there’s nothing a quick and short article can’t explain. Today’s topic is the total debt servicing ratio and how it can influence your application success rate. If the formula always seemed too complicated to understand, let today be the day you get to understand, once and for all, how to calculate it and become an expert in loans. Let’s now get started!
1. What Is the Total Debt Servicing Ratio (TDSR)?
The total debt servicing ratio is the formula by which Singapore moneylenders and other financial institutions determine your borrowing capacity. This is done in order to make sure you are able to pay your loan. This is important not only for the institution, as it offers it a realistic image of your borrowing capacity, but it is also important for you to know how things work.
In this article we’re going to explain what the total debt servicing ratio is, how it is calculated, what its role is in an application, and what can you do to improve this TDSR to increase your chances of loan approval.
They say a person’s desk illustrates a person’s life – if it is messy, it means their life is messy. Sam goes for your wallet. A messy wallet reflects chaos and instability and it attracts the same.
Here are some things you should do in order to avoid the attraction of chaos in your financial resources:
- Remove old receipts, loose change, random coins, expired or unused cards and any other unnecessary items.
- Empty out your wallet and rearrange your banknotes in ascending order.
- If you must keep some coins, make sure you keep them in a separate coin pouch.
- Look out for open seams or stains and if you notice any of them, it would be best that you clean or change it.
2.Why Is TDSR Important?
In mathematical terms, the TDSR is a financial metric that shows what percentage of a borrower’s gross monthly income goes toward debt repayment. This is a safety mechanism brought forward by Singapore moneylenders and other financial institutions such as banks that serves not only the institution, but the borrower as well. If you’ve ever turned down a loan because of the interest and you feared you wouldn’t be able to pay it back, know that this mechanism makes sure that you are able and capable of paying it off.
Financial institutions will not allow you to take a loan, unless you have the means to pay it back and that should be a reassurance for the borrower. Remember that the institution wants you to pay off your debts as much as you want to, so when it comes to a repayment mechanism, they are very invested in making it easy for you to complete your financial obligations.
Here is why TDSR is so important:
- It prevents borrowers from overleveraging. This mechanism shows exactly what your current payroll can afford to borrow.
- It helps financial institutions manage credit risks. No financial institution will risk overloading you for the sake of securing a client and this mechanism guarantees that.
- It ensures that borrowers have enough disposable income after paying off debts. If your payroll is enough for you to pay off your debt only, then it is not enough for you to secure a loan. You might be inclined to think you can do this, but this mechanism comes to calculate what is the maximum amount of money you can borrow without compromising your financial leverage and cash flow.
- It aligns with governmental regulations on responsible borrowing. This ensures that financial institutions don’t “rip you off” and make you take more than you can bear.
3. How to Calculate TDSR
The general formula is calculated by dividing your total monthly debt obligations by your total monthly gross income. This result is later on multiplied by 100 and there you have it, your total debt servicing ratio.
- In this formula, the total monthly debt obligations include mortgage payments, car, student or personal loans , and credit card payments.
- In this formula, the total monthly gross income includes one’s salary, rental income, bonuses, commissions, or any other types of regular income.
Example:
Let’s assume our friend John Smith has a monthly income of $8000. John has to pay a monthly mortgage payment of $2000, a car loan rate of $800 and a credit card payment of $400 All of these costs are more or less common for the regular Singaporean. These costs add up to $3200/ month.
The calculus is as follows: we take the monthly obligations ($3200) and we divide it by the monthly income ($8000) and then multiply it all by 100. This results in a percentage of 40. After finding this John is happy, because he is now eligible to get a new renovation loan.
4. How this TDSR Affects Loan Application
Now that we know what TDSR is, why it is important and how to calculate it, let us now see the ways in which it can impact your loan application.
If you want to get a money loan in Singapore, there are a few documents you would have to turn in. The number of documents required may differ from lender to lender and certain types of loans might require additional information, but typically all you need is proof of citizenship (or permanent residency), documents showing you’re above the age of 21, identity proof, income proof (computerized payslip/CPF/Bank statement), residency proof (such as household bills) and an employment contract for those who have been hired for less than 6 months.
Once you have this documentation, you are free to apply for a money loan in Singapore. Once you get to this step and begin the talks with the financial representatives, your TDSR will soon be calculated. Many countries have regulated the way in which TDSR is calculated. In Singapore, the Monetary Authority of Singapore (MAS) has set the TDSR cap at 55%. From this point on, there are three possible scenarios:
- Your TDSR exceeds the limit: if this is the case, then you will need to either reduce the amount of the loan or increase your income. In most of these cases, it is easier for you to reduce the amount, than it is to get an additional source of income.
- Your TDSR is at 55%, right on the limit. This is a risky move. Technically, you do qualify for the loan, but going for that amount might not be the most the wisest option. Try talking with your financial institutions and find the best option available, one that allows you to secure the amount of money you need without running the risk of compromising your financial resources.
- Your TDSR is below the limit: if that’s the case, congratulations, you are one step closer to securing a loan.
5. Factors That Influence TDSR
When it comes to factors of influence, there are quite a few elements that play a high role in determining your chances of obtaining a loan. It is very beneficial for you to understand the way in which these factors work so that you can maximize your chances of success.
- Monthly debt commitments: when it comes to this factor, every single type of recurrent payment that is paid on a monthly basis is taken into account. The more obligations you have as a borrower, the higher your TDSR will be an, as a consequence, the lower your chance of obtaining a loan is. These monthly payments can include but are not limited to mortgage payments, car loans, student loans, credit card balances, personal loans and overdrafts.
- Gross monthly income: now that we’ve tackled the spending, it is time we address the income. As we have seen in the formula, this also plays a great role in determining your TDSR. The general rule is that the higher the income, the lower the impacts, therefore the chances of obtaining a loan are higher. Some of the types of income can include but are not limited to, fixed salary, bonuses and commissions, rental income, investment dividends and freelance or business income.
- Interest rates and tenure: one important aspect that is not directly related to one’s purchasing power is the interest rate and the tenure. A longer loan tenure generally means a lower monthly repayment which translates into a lower TDSR. In contrast, shorter loan tenure increases the monthly repayment and that translates into a higher TDSR. That’s the general rule when it comes to tenure. Let us now address the role of interest rates. A high-interest rate increases the total debt servicing costs and that leads to a higher TDSR. On the other hand, a low-interest rate reduces the monthly repayment and that helps keep the TDSR manageable.
6. International Government and Banking Regulations
The TDSR is a mechanism that, as stated before, is used by multiple countries to manage financial institutions and calculate the borrower’s capability to pay off their loans. Some countries are stricter in terms of regulations, while other countries are more relaxed and offer more opportunities for loan seekers. Here are a few comparisons:
- In Singapore, as stated before, the limit is set at 55%.
- In Canada, this limit is set at 44%
- In the United States, the percentage varies between 36%-43%, depending on the money lender.
In addition to this, money lenders are free to add other internal policies that can further more restrict the access to a loan. Based on this comparison, we see that Singapore is one of the more relaxed countries in terms of limitations and that is because the Government is making an effort to support the citizens in their financial endeavours.
In short, the stricter the total debt servicing ratio is, the more difficult it is for people to access loans. The more relaxed the TDSR regulations are, the easier it is for people to access financing.
7. Common Misconceptions About TDSR
Now that we know all there is to know about TDSR, let us address some of the most commonly encountered misconceptions and debunk all of the myths surrounding the topic.
- Misconception no. 1: TDSR only applies to home loans. This is false. TDSR applies to all kinds of loans and is not limited to mortgages. Moreover, when calculating the TDSR, we have seen that all types of monthly costs are taken into account when determining the ratio.
- Misconception no. 2: I can take longer loan tenure and reduce my TDSR. While it is true that a longer tenure equals a lower TDSR, things are not that easy in real life and that is because these mechanisms are in place to keep both you and the financial institutions safe when it comes to monetary transactions. You might get a lower TDSR score which might increase your chances of getting a loan, but you also run the risk of paying a higher total interest rate over time. Talk with your money lender about the best option you should choose, they will be able to recommend you the option that is best suitable for your lifestyle.
- Misconception no. 3: If I earn more, I can take on unlimited debt. We would all like for that to be true, but, unfortunately, it is not. Not entirely, at least. Even with higher incomes, money lenders will set a limit when it comes to debt obligations. Having a higher salary increases borrowing capacity but does not mean unlimited borrowing. This is done in order to keep you safe, first of all, and then to ensure that you are able to pay off your debts without altering your lifestyle and without changing your cash flow
Conclusion:
We understand that some might find this TDSR as restrictive or see it as a limitation, but we urge you to remember that governments set this in place in order to protect you, first of all, from financial burden. Its role is to promote financial stability and responsible borrowing and lending.
If you’ve made it this far, congratulations! You are officially more financially knowledgeable than those who gave up on this article halfway through.
