Personal Loan (Flat Rate) in Singapore: Your Questions Answered
These are the questions people ask most often about personal loan (flat rate). Each answer is short; follow the links for the full detail.
What does a personal loan (flat rate) calculation tell me?
Singapore banks advertise personal loans at flat rates. This shows the instalment and the effective interest rate.
What is the formula?
Interest = P × flat rate × years; EIR is solved from the instalment stream.
What do I need to enter?
Loan amount (S$), Flat rate (% a year), Term (years).
Is this financial advice?
No. It is a calculation tool. For decisions about loans or investments, compare official offer documents and consider speaking to a licensed adviser.
Can you show an example?
For example, with these inputs:
- Loan amount (S$): 15,000
- Flat rate (% a year): 3.5
- Term (years): 3
the calculator returns:
- Monthly instalment: S$460.42
- Total interest: S$1,575.00
- Effective interest rate: 6.60%
Any tips?
- Compare loans by effective interest rate, not flat rate; the EIR is roughly double the flat rate.
- Use realistic return assumptions; long-term projections at high rates can be very misleading.
- Paying credit card bills in full avoids interest charges of around 27% a year or more.
Background
An emergency fund of three to six months of essential expenses protects you from having to borrow at high rates when something unexpected happens. Once that buffer is in place, extra savings can go towards longer-term goals and investments.
Compounding is the reason long-term saving works: returns earn further returns, so the growth curve steepens over time. The same maths works against you with debt, which is why credit card balances at around 27% a year grow quickly if only minimum payments are made.
Interest in Singapore is quoted in several ways. Mortgages and savings accounts use effective annual rates, while car loans and many personal loans are advertised at flat rates that look much lower than their true cost. Banks must disclose the effective interest rate, and comparing on that basis gives a fair picture.
