## What is Total Debt Servicing Ratio (TDSR)?

The Total Debt Servicing Ratio (TDSR) is a framework established by the Monetary Authority of Singapore (MAS) in 2013 to promote responsible lending and borrowing, encourage financial prudence and, in the long run, to curb the risk of a subprime meltdown.

## How to Calculate TDSR?

The rule of thumb of the TDSR states that your total monthly debt obligations **must not exceed 60%** of your gross household monthly income. This sets a cap on the maximum amount of money you can borrow from financial institutions for your monthly repayments.

Here is how TDSR is calculated:

## What is Mortgage Servicing Ratio (MSR)?

The Mortgage Servicing Ratio (MSR) is a sub-component of the TDSR which is a key element to consider when applying for a home loan.

MSR dictates that your total monthly mortgage repayments **must not exceed 30%** of your gross household monthly income.

It is important to note that the 30% MSR cap is included in the 60% TDSR limit. Simply said, if your MSR is 30% of your gross household monthly income, you have a remainder of 30% for your other financial commitments for example Car loans, credit cards, etc.

Here is how MSR is calculated:

### An example to illustrate TDSR and MSR

Say your gross household monthly income is S$10,000.

The TDSR’s threshold is 60% of your gross household monthly income, which is S$6,000. This is the maximum sum of your total monthly repayments.

The MSR’s threshold is 30% of your gross household monthly income, which is S$3,000. This is the maximum sum of your monthly mortgage repayments.

Over a loan tenure of 25 years, with a monthly mortgage repayment of S$3,000, you can borrow up to S$900,000 for a home loan.

This means the remaining 30% of your other monthly debt obligations (excluding home loan repayments) can be up to S$3000 to pass the 60% TDSR cap.
