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.
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.
