Highlights
How the Calculations Work
1. Financial Performance Formula
The core calculation uses the following structure:
| Field | Description | Formula |
|---|---|---|
| Gross Income | Income before any deductions | Gross Rent + Other Income |
| Gross Yield % | Gross annualized return on investment | (Annual Gross Income / Purchase Price) × 100 |
| Operational Expenses | Total running costs | Sum of expense categories |
| Net Income | Post-tax cash flow after all expenses | Gross Income - Operational Expenses - Tax - Financing Costs |
| Net Yield % | Net annualized return on investment | (Annual Net Income / Purchase Price) × 100 |
| Break-Even Rent | Minimum rent required to cover costs (pre-tax) | Operational Expenses + Financing Costs - Other Income |
| Total Tax | Combined sum of income, corporate, and dividend taxes | Income Tax + Corporate Tax + Dividend Tax - Mortgage Interest Tax Credit |
2. Tax Calculations by Ownership Type
The calculator supports three distinct ownership structures, each with different tax implications and calculation methods. Understanding these differences is crucial for accurate yield analysis and tax planning.
Choose your ownership structure based on your situation.
Personal Ownership
Personal ownership offers personal allowances and progressive tax bands, but financing costs are not deductible from pre-tax income.
| Category | Detail | Value |
|---|---|---|
| Personal Allowance | — | £12,570 |
| Tax Bands | Basic | 20% (£12,571–£50,270) |
| Higher | 40% (£50,271–£125,140) | |
| Additional | 45% (above £125,141) | |
| Mortgage Interest Relief | — | 20% credit (22% from 2027-28) |
Limited Company
A limited company structure allows full expense deduction but subjects profits to corporation tax rates.
| Category | Detail | Value |
|---|---|---|
| Corporation Tax | Small Profits Rate | 19% (up to £50,000) |
| Main Rate | 25% (above £250,000) | |
| Marginal Relief | Graduated rate (£50,001–£249,999) | |
| Expense Deduction | Operating Costs | Fully deductible |
| Finance Costs | Fully deductible |
Limited Company + Dividends
Limited company + dividends combines corporate taxation with dividend tax on extraction of profits.
| Category | Detail | Value |
|---|---|---|
| Corporation Tax | Small Profits Rate | 19% (up to £50,000) |
| Main Rate | 25% (above £250,000) | |
| Marginal Relief | Graduated rate (£50,001–£249,999) | |
| Dividend Allowance | — | £500 |
| Dividend Tax Bands | Basic | 8.75% (up to £37,700) |
| Higher | 33.75% (£37,701–£125,140) | |
| Additional | 39.35% (above £125,141) |
3. Portfolio Calculations
How multiple properties are handled depends on your tax treatment selection:
Progressive Tax Treatments (calculated)
When using progressive tax calculations:
- Total income and expenses are aggregated across all properties
- Personal allowance and tax bands are applied to the combined portfolio income
- Tax liabilities are distributed proportionally back to individual properties
- Optimizes total tax liability by considering the entire portfolio
Flat Rate Tax Treatments (basic rate, higher rate, additional rate)
When using flat rate tax calculations:
- Each property is calculated independently - no portfolio aggregation
- Flat rate applied to each property separately (20%, 40%, or 45%)
- No personal allowance applied to any property
- Portfolio dynamics are ignored - properties don't benefit from combined income
3. Tax Efficiency Analysis
Your tax breakdown reveals where income is being reduced and how efficiently your ownership structure manages liability.
| Ownership | Common Efficiency Signals | Watch For |
|---|---|---|
| Personal | Mortgage interest relief limited to basic-rate credit (20%; 22% from 2027-28 per Budget 2025). Efficient at lower income levels. | Diminished returns for higher-rate taxpayers. |
| Ltd Co | Full expense deduction allowed, subject to corporation tax (19–25%). | Profits retained in company may be tax-efficient short term but taxed later if extracted. |
| Ltd Co + Dividends | Combines corporation and dividend tax. Optimal if profits are shared across lower-rate shareholders. | May reduce take-home yield due to double taxation. |
Reference: HMRC Corporation Tax Act 2010; HMRC Dividend Tax Rates, April 2025.
Tip: If your effective tax rate exceeds 35% of pre-tax income, consider reviewing corporate structuring or reinvestment strategies to defer extraction.
6. Example Comparison
| Ownership Type | Pre-Tax Yield | Post-Tax Yield | Notes |
|---|---|---|---|
| Personal (Higher Rate) | 6.2% | 3.8% | Limited mortgage relief and higher tax rate |
| Ltd Co | 6.2% | 4.9% | Corporation tax applies, but full cost deductions |
| Ltd Co + Dividends | 6.2% | 4.3% | Combined effect of corporation and dividend tax |
