Shared Ownership Calculator UK

Shared ownership is a government-backed scheme that allows you to:

• Buy a percentage (usually 10%–75%) of a property
• Pay rent on the remaining share
• Gradually increase ownership over time (called “staircasing”)

It’s designed to make homeownership more affordable.

How Shared Ownership Costs Are Calculated

Step 1: Calculate Your Share Value

Property Value × Ownership %

Step 2: Mortgage Amount

Share Value – Deposit

Step 3: Monthly Mortgage Payment

Based on interest rate and loan term

Step 4: Rent on Remaining Share

Usually around 2%–3% annually of unsold share

Example Calculation

If a property is worth £300,000 and you buy 25%:

• Share value = £75,000
• Deposit = £7,500
• Mortgage = £67,500

You’ll also pay rent on the remaining 75%.
