Background
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.
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.
