Shared Ownership Calculator UK
Buying a home can be challenging, especially with rising property prices. The Shared Ownership Calculator UK by Accotax helps you understand the real cost of buying a shared ownership property by estimating both mortgage payments and rent on the remaining share. Shared ownership schemes allow you to purchase a percentage of a property (usually between 25% and 75%) while paying rent on the rest. This calculator helps you see the full monthly cost so you can decide whether shared ownership is affordable for you.
Shared Ownership Formula (How It Is Calculated)
The calculator estimates total monthly housing costs using:
1. Mortgage Payment
Mortgage = (Share of Property Price – Deposit) × Interest Rate ÷ 12
2. Rent Payment
Rent = Remaining Share × Property Value × Rental Rate
3. Total Monthly Cost
Total Cost = Mortgage Payment + Rent + Service Charges (if applicable)
Example:
- Property value: £250,000
- Your share: 40% (£100,000)
- Remaining share: 60% (£150,000)
- Mortgage payment: £450/month
- Rent: £600/month
Total monthly cost = £1,050
