Mortgages Explained: Your Payment Is Not the Whole Bill

Episode notes and examples

Alex can afford the mortgage payment. Has the roof approved his calculation?

A country-neutral guide to understanding mortgages with Alex, Maya, Leo, Nina and Ben. Learn what you borrow, how principal and interest work, what equity means, why a longer repayment period can cost more in interest, and why the loan payment is only part of a housing budget.

This episode explains general concepts, not one country's mortgage system. Dollar amounts are invented teaching examples, not US-specific guidance, market quotes, or recommended loan terms. Local laws, contribution requirements, taxes, fees, interest calculations, renewal rules and typical loan structures vary. A fixed-rate period may be shorter than the repayment period. Some structures leave principal outstanding.

ILLUSTRATIVE MATH Home price: $300,000. Upfront contribution: $60,000. Borrowing: $240,000. The contribution shown is not a universal minimum.

For the worked example only, assume a fully amortizing loan, nominal annual interest of 6%, monthly rate 0.06/12, rate unchanged throughout, equal monthly payments, no fees and no extra repayments: • 30 years: $1,438.92 monthly principal + interest; approximately $278,012 total interest. • First payment: $1,200 interest and about $238.92 principal. • 15 years at the same assumed rate: $2,025.26 monthly principal + interest; approximately $124,546 total interest.

Spoken figures and charts round these amounts for readability, including total interest of about $278,000 and $125,000. Totals use the unrounded payment formula. Taxes, insurance, maintenance, fees and other ownership costs are outside this loan calculation.

BEFORE BORROWING Know your upfront cash requirement, full monthly costs, possible rate changes, and debt remaining. Compare written offers with equivalent assumptions over your likely ownership period. Avoid counting charges twice if the lender collects them. Check your actual contract and local requirements.
