Deposit calculator
See how much deposit you'll need for your target property price, where you are today, and how long it'll take to hit common deposit milestones at your current saving rate.
Most UK lenders look for at least a 5% deposit. A 10–15% deposit unlocks much wider product choice and lower rates.

Estimate based on consistent monthly saving and a fixed target price. Doesn't include investment growth, interest earned, or property price changes over time.
Why deposit size matters
The bigger your deposit, the lower your Loan to Value (LTV) — and the lower the interest rate you may be offered. The biggest rate improvements often come as you reach 10%, 15%, 20% and 25% deposit levels — equivalent to 90%, 85%, 80% and 75% LTV.
Ways to boost your deposit
- Open a Lifetime ISA — the government adds a 25% bonus on contributions up to £4,000 per year.
- Family gifts can usually be used as deposit, provided lenders see a signed letter confirming the funds aren't a loan.
- Some lenders accept proceeds from the sale of another property, shares, or bonds.
