Comparing

Buy vs rent calculator

Where your money ends up if you buy or keep renting over time.

  • What it means

    This compares roughly where your money ends up if you buy a home or keep renting over several years.

  • Why it matters

    Buying builds ownership over time. Renting can leave cash free to save or invest. The better path depends on your numbers.

  • When to use it

    Use it when you are torn between buying and renting, and you can make honest guesses about growth, rent rises and how long you will stay.

  • How to read the result

    Look for the break-even year and the gap at the end. It is a model from your assumptions, not a life decision on its own.
