Background
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.
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.
