House Deposit — £25,000 Goal Over 5 Years

Saving for a house deposit is one of the biggest financial goals most people face. With average UK house prices around £285,000, a 10% deposit of roughly £28,500 feels daunting — but it is absolutely achievable with consistent monthly saving and a solid plan. This scenario walks through a realistic 5-year savings plan for a £25,000 deposit, showing exactly how to use our calculator to track progress and stay on course.

The Profile

Step-by-Step Walkthrough

Priya and James use the Goal mode calculator with target £25,000, starting balance £3,000, interest rate 4.4%, time period 5 years, and monthly compounding. The calculator shows they need to save approximately £338 per month between them — that is £169 each, or roughly £39 per week each.

Switching to Growth mode to verify: starting balance £3,000, monthly contribution £338, interest rate 4.4%, 5 years. The projected final balance is approximately £25,200. Of this, £3,000 is their initial savings, £20,280 comes from monthly contributions, and roughly £1,920 is compound interest earned. The year-by-year breakdown shows interest accelerating from about £200 in year 1 to over £600 in year 5 as the balance grows.

They could also use a Lifetime ISA (LISA) for part of their savings, which gives a 25% government bonus on contributions up to £4,000 per year. That is up to £1,000 per year in free money — an additional £5,000 over 5 years. With LISA bonuses factored in, they could reduce their monthly savings target or reach £25,000 faster. Note that LISA funds can only be withdrawn penalty-free for a first home purchase or after age 60.

Key Takeaways

• •£25,000 in 5 years requires roughly £340/month for a couple — £170 each
• •Nearly £2,000 of the total comes from interest alone
• •Consider a Lifetime ISA for the 25% government bonus
• •Use a Cash ISA to shelter interest from tax
• •Review and adjust annually — rates and house prices change

Frequently Asked Questions

Is 5% or 10% deposit better?

A larger deposit typically means lower mortgage rates and lower monthly payments. However, many lenders accept 5% deposits. The right answer depends on your circumstances, local housing market, and how long you are willing to save. Use our Goal mode to model both targets.

Should I invest instead of saving for a deposit?

For a 5-year timeline, investing carries meaningful risk — stock markets can and do fall significantly over 5-year periods. Cash savings are lower risk and more predictable. If your timeline is 7+ years, a mix of investments and cash may be appropriate, but for most first-time buyers, cash savings or a LISA are more suitable.
