## Key takeaways

- Set a target deposit as a percentage of a realistic property price, then add buying costs on top.
- A larger deposit usually unlocks better mortgage rates, so saving more can lower your monthly payments.
- A Lifetime ISA can add a government bonus when saving for a first home, within the rules.
- Work backwards from your target and timeline to find the monthly amount you need to save.
- This is general information, not financial advice.

Saving for a house deposit is one of the biggest financial goals most people take on, and the size of the number can make it feel out of reach. Broken into a target, a timeline and a monthly amount, though, it becomes a plan rather than a wish. *This is general information, not financial advice.*

## What a deposit is and why it matters

**A house deposit is the lump sum you pay upfront towards a property, with a mortgage covering the rest.** It is usually expressed as a percentage of the purchase price — so on a 200,000 pound home, a 10 percent deposit is 20,000 pounds.

The deposit does more than get you through the door. **The larger your deposit, the lower your loan-to-value (LTV) ratio**, and lower-LTV borrowers typically qualify for better mortgage rates. In other words, saving a bigger deposit can reduce both the amount you borrow and the interest rate on it, which lowers your monthly payments. That is why stretching the deposit a little further often pays off long after you have the keys.

Smaller-deposit mortgages do exist, which can help people buy sooner, but they generally come with higher rates. There is a genuine trade-off between buying earlier with less and waiting to save more — and the right answer depends on your circumstances and the local market.

## Step one: set a realistic target

Vague goals are hard to hit, so start by pinning down a number.

1. **Estimate a realistic property price** for the kind of home and area you are aiming at. Look at what similar properties actually sell for, not just asking prices.
2. **Decide on a deposit percentage.** A larger percentage means better rates; a smaller one means buying sooner. Pick a figure you can realistically reach.
3. **Add the buying costs.** Beyond the deposit you will face legal fees, a survey, mortgage arrangement fees, removals and possibly Stamp Duty depending on the price and whether you are a first-time buyer.

> Your real target is the deposit *plus* the cost of buying. Saving only for the deposit and forgetting the fees is a common way to fall short at the final hurdle.

Writing down a single, specific target — say "28,000 pounds, including fees" — turns an abstract ambition into something you can plan around.

## Step two: use the right account

Where you keep the money matters, both for safety and for any boost you can get.

**Keep it in cash, not investments.** A deposit is usually a short- to medium-term goal, and money you may need within a few years does not belong in the stock market, where it could fall in value at the wrong moment. A competitive savings account or Cash ISA is the typical home for deposit savings — the same low-risk, accessible approach used for an [emergency fund](/business-finance/how-to-build-an-emergency-fund).

**Consider a Lifetime ISA (LISA).** This is the standout option for many first-time buyers. A LISA adds a **government bonus** on top of what you pay in, up to an annual limit, and can be put towards a first home — effectively free money for your deposit. But the rules are specific:

- There are **age limits** for opening one and paying in.
- The property must be within a **price cap** and the account open for a **minimum period** before you can use it for a home.
- Taking money out for anything other than a first home or retirement usually triggers a **withdrawal charge** that can leave you with less than you put in.

Because the details matter and can change, check the current LISA rules on GOV.UK before relying on one. Our guide to [ISAs and the tax-free wrapper](/business-finance/isas-explained) explains how the LISA fits alongside other account types.

## Step three: work out your monthly amount

With a target and a timeline, the monthly figure falls out of simple arithmetic.

Divide your total target by the number of months you have. If you need 28,000 pounds in five years, that is 60 months, or about **467 pounds a month** — before any savings interest or LISA bonus, which reduce what you need to put in yourself.

| Target | Timeline | Roughly per month (before interest/bonus) |
|---|---|---|
| 20,000 | 4 years | about 417 |
| 28,000 | 5 years | about 467 |
| 40,000 | 6 years | about 556 |

If the monthly figure looks impossible, you have three honest levers: **save for longer**, **lower the target** (a smaller deposit or cheaper property), or **increase what you save each month**. Seeing the trade-offs clearly is far better than hoping the gap closes on its own.

## Step four: build the saving habit

Hitting the number month after month is where plans succeed or fail. A few habits make it far more reliable:

- **Automate it.** Set up a standing order to move your deposit savings on payday, before the money can be spent.
- **Treat it as a sinking fund.** The same approach used for big planned costs works here; our guide to [sinking funds for large planned costs](/business-finance/sinking-funds-explained) shows how to ring-fence the money.
- **Cut fixed costs first.** Trimming a recurring bill frees up the same amount every single month, which adds up faster than occasional one-off savings. A clear [monthly budget](/business-finance/how-to-make-a-budget) makes those opportunities obvious.
- **Bank windfalls.** Bonuses, tax refunds and gifts can give your deposit a useful jump if you route them straight to savings.

It also helps to keep a separate emergency fund so that an unexpected bill does not force you to raid your deposit pot — progress towards a house should not come at the cost of financial safety.

## A note on getting ready to buy

Saving is only part of being mortgage-ready. Lenders look at your wider finances, so it is worth keeping your credit in good shape and your spending stable in the run-up to applying. As the goal nears, free and impartial help from MoneyHelper can guide you through the buying process, and Citizens Advice covers your rights and the practical steps of purchasing a home.

## The bottom line

Saving for a house deposit becomes manageable once you turn it into a plan: set a realistic target that includes buying costs, keep the money in cash, make the most of a Lifetime ISA bonus if it suits you, and work backwards to a monthly amount you can automate. A larger deposit usually means cheaper borrowing, so every extra pound saved can keep working for you long after you move in.

## Frequently asked questions

### How big a deposit do I need to buy a house?

Deposits are usually quoted as a percentage of the property price. A larger deposit generally means access to better mortgage rates, while smaller-deposit mortgages exist but often cost more in interest. There is no single right figure; it depends on the property and lender. This is general information, not financial advice.

### What is a Lifetime ISA and how does it help with a deposit?

A Lifetime ISA is a savings account for first-time buyers and retirement that adds a government bonus to what you pay in, up to an annual limit. It can be used towards a first home within certain rules, including price caps and how long the account has been open. Check current rules on GOV.UK.

### Should I save my deposit in cash or invest it?

Money you may need within a few years is usually kept in cash savings so its value is not exposed to market falls. Investing carries the risk of getting back less than you put in, which is a poor fit for a near-term goal like a deposit. Your circumstances matter, so consider free guidance from MoneyHelper.

### What costs are there besides the deposit?

Buying a home involves extra costs such as legal fees, a survey, mortgage fees, removals and possibly Stamp Duty depending on the price and your circumstances. It is wise to budget for these on top of the deposit itself so they do not catch you out.
