Loans & Credit

Borrowing is where financial institutions are most creative with arithmetic, and where a plain-numbers explanation pays for itself fastest. This section breaks down how loan interest actually works: the difference between an advertised rate and an APR, how amortisation decides how much of each payment reaches the principal, why credit card balances compound daily against you, and how the grace period disappears the moment you carry a balance. We compare the debts most households hold – mortgages with their points, PMI and refinancing traps; student loans with capitalised interest and subsidy rules; auto loans with negative equity risk – and lay out which balances deserve extra payments first. The aim is not to shame anyone for borrowing; credit is a tool. The aim is to show the true cost of each form of it, in worked examples with real figures, so the next loan you sign is one you chose with the full picture in view.
