Rent Affordability Table
Rent affordability indicates how much you can spend on rent based on your gross annual income, with the common benchmark used by landlords and letting agents being approximately 30% of your gross monthly income. Understanding what rent you can afford is a crucial first step, as it allows you to easily calculate the maximum monthly rent that fits within your budget based on your annual earnings.
Below table shows the monthly rent and the annual income expected based on the 30% rent-to-income rule, as well as the guarantor’s annual income requirement if one is needed.| Monthly Rent | Annual Income (30x) | Guarantor (36x) |
|---|---|---|
| £300 | £9,000 | £10,800 |
| £400 | £12,000 | £14,400 |
| £500 | £15,000 | £18,000 |
| £600 | £18,000 | £21,600 |
| £700 | £21,000 | £25,200 |
| £800 | £24,000 | £28,800 |
| £900 | £27,000 | £32,400 |
| £1,000 | £30,000 | £36,000 |
| £1,100 | £33,000 | £39,600 |
| £1,200 | £36,000 | £43,200 |
How is Rent Affordability Calculated?
Most letting agents and landlords use the standard UK income-to-rent ratio when assessing applications. The general rule of thumb is that your annual income should be at least 30 times the monthly rent. Guarantors, if required, typically need to earn 36 times the monthly rent.Annual Income ≥ Monthly Rent × 30
If your rent is £500/month, you should earn at least:
£500 × 30 = £15,000 per year
Alternatively, you can multiply the yearly rent by 2.5 times for a quicker calculation. For example, if the monthly rent is £500, you’ll need an annual income of £15,000 to comfortably afford it.
Monthly Income ≥ Monthly Rent × 2.5
If rent is £500/month, your monthly income should be:
£500 × 2.5 = £1,250/month
➡️ Which equals £15,000/year
Guarantor Requirements
If your income falls below the required threshold, a landlord may ask for a guarantor. Guarantors are generally expected to earn at least 36 times the monthly rent per year, giving landlords added reassurance and making your application stronger.
For a monthly rent of £900, the figures would look like this:
Required Tenant Income (×30):
£900 × 30 = £27,000/year
Required Guarantor Income (×36):
£900 × 36 = £32,400/year
Why Rental Affordability Matters?
Renting is one of the biggest financial commitments you’ll make, and getting it right from the start makes all the difference. The rental affordability calculator takes the guesswork out of the process, giving you a clear, honest picture of what you can comfortably afford before you start your search.
Avoid Financial Stress: Taking on more rent than you can manage is one of the most common mistakes renters make. The rental affordability calculator helps you identify a realistic rental range, so your monthly payments never come at the cost of essentials like groceries, household bills, or building your savings.
Balance Rent with Real Life: Knowing how much rent you can afford helps you manage other monthly obligations, such as Council Tax, transport, and food expenses, without compromising your lifestyle.
Speed Up Your Rental Search: With a clear idea of how much rent you can afford, you can focus only on properties that are more targeted, an efficient search from day one of your budget. No wasted viewings, disappointing rejections, or time spent viewing homes that aren’t a financial fit.
Strengthen Your Rental Application: Letting agents and landlords follow the same affordability checks across the board. Knowing your numbers in advance means you can apply with confidence, already aware that you meet the income thresholds most landlords expect.
Make Smart, Informed Choices: Whether you’re weighing up two properties, relocating to a new city, or reassessing your budget after a change in circumstances, the rental affordability calculator gives you the data to support long-term, stress-free decisions.

Frequently Asked Questions
What counts as income for a rental affordability check?
Most letting agents and landlords count your gross income as the income for the affordability check. Gross income is the earnings before tax and National Insurance deductions. If you're employed, this is your annual salary figure on your contract. If you're self-employed, agents typically look at your last two to three years of accounts or SA302 tax returns. Benefits, pension income, and rental income from other properties may also be considered, depending on the landlord or agent's policy.
Does this rental affordability calculator account for scottish rental law?
The affordability ratios used here, i.e., 30x and 36x, are the standard guidelines followed by letting agents across Scotland and the United Kingdom. Scottish tenancies are governed by the Private Residential Tenancy (PRT) framework, which provides open-ended tenancy agreements. Affordability rules themselves are set by individual agents rather than legislation.
How is rental affordability calculated for house shares?
For shared properties, the total rent is divided equally among all tenants named on the tenancy. Each tenant's individual share of the rent is then assessed against their own income using the 30× rule.
What if my income doesn't meet the 30x rule?
You might need a guarantor, often requiring 36x the rent in annual income. Alternatively, look at more affordable areas or shared housing. We can help you explore Dundee options or strengthen your application.
Do landlords check affordability, and what documents do I need?
Yes, most run credit checks and verify income. You’ll usually need three months’ bank statements, recent payslips, and an employer reference. Having everything ready speeds up the process.
How do I factor in deposits and upfront costs?
You should plan for 1–1.5 months’ rent as a deposit plus the first month upfront. That’s typically £1,000–£3,000 in total. Our calculator can help check if your income comfortably covers this.
What's the difference between gross and net income for affordability?
Gross income is before tax; net is after tax. Landlords assess gross, but budgeting with net is more realistic. Use both figures in our tool for a clear picture.
Can students or low-income renters afford UK properties?
Yes, guarantors and shared rentals make it possible. In Dundee, student rents average £400–£600 a month. We offer tailored advice to match your budget.
How can I improve my rent affordability?
Cut back on non-essentials, boost income with side work, or consider build-to-rent options with bills included. We offer free consultations to create a strategy for you.
