Should you pay off your mortgage early or invest the extra cash? This classic personal finance debate is often framed as emotional peace of mind versus financial optimization. Paying off a mortgage guarantees a 'return' equal to your interest rate, while investing in the stock market historically yields higher but volatile returns.
To make an informed decision, you must simulate the long-term mathematical compound impact of both choices. Paying down debt reduces monthly cash obligations, while investing leverages compound growth over decades.
