Why Calculating Buy to Let Costs Matters
Properly estimating your Buy to Let expenses helps in:

- Avoiding unexpected financial strain

- Comparing properties and opportunities effectively
Skipping any of these cost calculations could result in lower than expected returns—or worse, financial loss.
Formula Used
While the calculator automates everything, here’s a simplified formula breakdown:
Total Upfront Costs = Purchase Price + Stamp Duty + Legal Fees + Mortgage Fees
Annual Ongoing Costs = (Letting Agent Fees + Maintenance + Insurance + Service Charges + Ground Rent)
Net Income = Annual Rental Income – Annual Ongoing Costs
Net Rental Yield (%) = (Net Income / Total Upfront Costs) × 100
This allows you to evaluate both short-term and long-term profitability.
Example Calculation
Let’s say you’re purchasing a rental property with the following details:
- Property Price: £250,000
- Stamp Duty: £10,000
- Legal Fees: £2,000
- Mortgage Fees: £1,500
- Letting Agent Fees: 10% of annual rent (£1,500 on £15,000)
- Maintenance: £1,200/year
- Insurance: £400/year
- Ground Rent & Service Charges: £600/year
Total Upfront Costs =
£250,000 + £10,000 + £2,000 + £1,500 = £263,500
Annual Ongoing Costs =
£1,500 (agent) + £1,200 + £400 + £600 = £3,700
Net Rental Income =
£15,000 (rental income) – £3,700 = £11,300
Net Rental Yield =
(£11,300 / £263,500) × 100 = ~4.29%
This means your property yields 4.29% annually after expenses.
