How to save for a house deposit

A deposit is usually the biggest thing standing between you and your first home. The good news is that it is a savings goal like any other, and a clear plan makes it far less daunting.

Key takeaways

  • A deposit is the share of a home's price you pay yourself; a larger one usually means a smaller loan and lower monthly costs.
  • Set a realistic target from the price range where you want to buy, and treat it as a range, not an exact figure.
  • Turn the target into a monthly amount by dividing what you need by the months you have.
  • Make the saving automatic with a fixed transfer on payday, and keep the money in a safe, separate account.
  • Break the big number into milestones to stay motivated over the long haul.

Why does the deposit matter?

A deposit is the share of a home's price you pay yourself, with the rest covered by a mortgage. A larger deposit usually means you can borrow less, which keeps your monthly costs lower and gives the lender more confidence in you.

A larger deposit usually means you can borrow less, which keeps your monthly costs lower and gives the lender more confidence in you. It is worth treating it as a serious, long-term goal rather than something you hope to scrape together at the end.

Work out a realistic target

Start by getting a rough idea of the kind of home you want and roughly what that costs where you plan to live. Lenders usually expect the deposit to be a set share of the price, so once you know the price range, you know roughly the sum you are aiming for. Treat it as a range, not an exact figure, and revisit it as your plans firm up.

Remember that buying a home comes with costs beyond the deposit itself, such as fees and moving expenses. Building a little extra on top of your target means those do not derail you at the finish line.

Turn the target into a monthly amount

Once you have a target and a timeline, the rest is arithmetic. Divide the amount you need by the number of months you have, and you get the monthly saving that gets you there. If that number feels impossible, you have two honest levers to pull: save a bit more each month, or give yourself more time. Both are better than a plan you cannot keep.

Make the saving automatic

The single biggest thing you can do is set up a fixed transfer to a separate account on the day your salary arrives. When the money moves before you have a chance to spend it, saving stops being a monthly decision and becomes a habit. Treat it like rent: not up for negotiation, and paid first.

Where to keep the money

Money you will need within a few years is usually best kept somewhere safe and easy to reach, such as a dedicated high-interest savings account, rather than invested where its value can swing. Keeping it in a separate account, away from your everyday spending, also makes it far less tempting to dip into.

Stay motivated for the long haul

Saving for a deposit takes time, and it is easy to lose steam. Break the big number into smaller milestones and mark each one as you reach it. Watching the balance climb month after month is motivating in itself, and that is much easier when your accounts are gathered in one place so you can follow the progress.

Frequently asked questions

How big should a house deposit be?
It varies by where you live and what lenders expect, but a common approach is to aim for a set share of the purchase price. A larger deposit usually means a smaller loan and lower monthly costs, so saving more than the minimum is rarely wasted.
How long does it take to save a deposit?
That depends on your target and how much you can put aside each month. Work out the monthly amount that reaches your goal in the time you have, and adjust either the amount or the timeline until the plan is one you can actually keep.
Where should I keep my deposit savings?
Money you will need within a few years is usually best in a safe, easily accessible account such as a high-interest savings account, kept separate from your everyday spending so you are not tempted to use it.
