Home Loans and Financing

Loans and Financing

Complete guides on mortgages, refinancing, auto loans, student loans, and all types of personal and business financing.

What this section covers

A loan comparison is only meaningful when you compare the same thing. Two mortgages quoted at the same rate can differ by tens of thousands over their life, because of how the interest is calculated, what fees are rolled in, how the rate resets, and whether the term is ten or thirty years.

These guides cover mortgages, refinancing, home equity borrowing, auto loans and student loans. Each one breaks the product down into the handful of numbers that actually drive the cost, then shows a worked example so you can see where the money goes rather than taking a rate at face value.

Every calculation shown in these guides is reproduced in the site calculators, so you can substitute your own figures and check the result.

How to use this section

  1. 1
    Read the guide for the loan type you are considering before you apply anywhere — the terms you are offered will make far more sense afterwards.
  2. 2
    Enter your own numbers in the loan, mortgage, refinance or amortisation calculators to see your true monthly cost.
  3. 3
    Compare a shorter term against a longer one on total interest, not just on the monthly payment. The cheaper monthly figure is often the more expensive loan.

Common questions

Should I choose the lowest rate or the lowest payment?

For the same term, the lowest rate wins. Across different terms they are not comparable: a longer term lowers the payment but raises total interest, sometimes dramatically. Decide how much total cost you can accept first, then find the lowest rate within that term.

How much does a 0.5% rate difference actually cost?

On a 300,000 loan over 30 years, half a percentage point is roughly 30,000 in extra interest. On a 20,000 car loan over five years, the same half point is closer to 250. Rate differences matter in proportion to the balance and the term.

Is it worth refinancing for a small rate reduction?

Only if the interest saved exceeds the closing costs before you expect to move or repay. As a rough test, divide the total closing costs by the monthly saving to get the break-even month, and compare that with how long you realistically expect to keep the loan.
