Markup in Singapore: 5 Mistakes to Avoid
Finds the selling price from cost and markup. The maths is not complicated, but a handful of errors come up again and again in this and related loans & finance calculations. Here is what to watch for.
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.
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.
1. Paying only the minimum on a card
Minimum payments barely cover interest, so balances can take years to clear.
2. Comparing flat rates with effective rates
A 3% flat rate can be close to 5.5% effective because interest is charged on the original amount for the whole term.
3. Using unrealistic returns
Projecting 10% a year for decades can make goals look easy; test lower rates too.
4. Only looking at the monthly payment
A longer tenure lowers the instalment but raises the total interest paid.
5. Forgetting inflation
S$1 million in 30 years will buy much less than S$1 million today.
The correct method
Price = cost × (1 + markup).
For example, with these inputs:
- Cost (S$): 40
- Markup (%): 50
the calculator returns:
- Selling price: S$60.00
- Resulting margin: 33.33%
