Markup Formula Explained, With Examples
Every markup 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
Price = cost × (1 + markup).
What each input means
- Cost (S$): the value you enter in the calculator.
- Markup (%): the value you enter in the calculator.
Example
For example, with these inputs:
- Cost (S$): 40
- Markup (%): 50
the calculator returns:
- Selling price: S$60.00
- Resulting margin: 33.33%
How the result changes
The table keeps the other inputs at their example values and changes cost (s$).
| Cost (S$) | Selling price | Resulting margin |
|---|---|---|
| 40 | S$60.00 | 33.33% |
| 20 | S$30.00 | 33.33% |
| 30 | S$45.00 | 33.33% |
| 50 | S$75.00 | 33.33% |
| 60 | S$90.00 | 33.33% |
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.
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.
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.
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.
