Worked example
For example, with these inputs:
- Balance (S$): 5,000

- Monthly payment (S$): 300
the calculator returns:
- Months to pay off: 22 months

Background
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.
