Maximum Car Loan Formula Explained, With Examples
Every maximum car loan result comes from one formula. Once you understand what goes into it, you can sanity-check any figure you are given, whether by an employer, a bank, a teacher or another website.
The formula
Max loan = price × 70% (OMV ≤ S$20,000) or 60% (OMV > S$20,000).
What each input means
- Open Market Value (OMV) (S$): the value you enter in the calculator.
- Purchase price (S$): the value you enter in the calculator.
Example
For example, with these inputs:
- Open Market Value (OMV) (S$): 25,000
- Purchase price (S$): 140,000
the calculator returns:
- Maximum loan: S$84,000.00
- Minimum downpayment: S$56,000.00
How the result changes
The table keeps the other inputs at their example values and changes open market value (omv) (s$).
| Open Market Value (OMV) (S$) | Maximum loan | Minimum downpayment |
|---|---|---|
| 25,000 | S$84,000.00 | S$56,000.00 |
| 12,500 | S$98,000.00 | S$42,000.00 |
| 18,750 | S$98,000.00 | S$42,000.00 |
| 31,250 | S$84,000.00 | S$56,000.00 |
| 37,500 | S$84,000.00 | S$56,000.00 |
Why it matters
Interest rates, instalments and returns compound over years, so a small difference in rate or tenure turns into thousands of dollars. Working the numbers out yourself makes it easier to compare bank offers, avoid expensive debt and plan savings goals.
Calculators make it easy to compare scenarios side by side: a shorter tenure versus a lower instalment, a higher deposit versus more cash in hand, or paying down debt versus investing. Seeing the total cost, not just the monthly figure, usually makes the better choice obvious.
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.
Inflation erodes buying power, so a savings goal set in today's dollars needs to be adjusted upwards for the years it will take to reach it. Singapore's core inflation has varied widely over the past decade, so it is worth testing a range of rates.
