House Affordability Calculator: Check Local House Prices Against Earnings
The House Affordability Calculator helps buyers understand how affordable homes may be in different parts of England and Wales by comparing local house prices with local earnings.
Simple answer: This calculator helps you see whether homes in an area look affordable when compared with typical earnings. It is useful for first-time buyers, home movers, relocating families and anyone comparing different areas before starting a property search.
This calculator is provided by the Office for National Statistics, also known as the ONS. It is not a mortgage approval tool, but it can help buyers understand local housing affordability before speaking to a mortgage adviser or viewing properties.

What Does House Affordability Mean?
House affordability usually means how easy or difficult it is for people to buy a home based on local property prices and local income.
A common way to measure this is the house price to earnings ratio. This compares the average or median house price in an area with average or median earnings.
| Term | Simple Meaning |
|---|---|
| House price | The typical price paid for homes in an area. |
| Earnings | The typical income people earn in that area. |
| Affordability ratio | How many years of earnings may be needed to match the house price. |
| Lower ratio | The area may be more affordable compared with local earnings. |
| Higher ratio | The area may be less affordable compared with local earnings. |
Example: If the typical house price in an area is £300,000 and typical annual earnings are £40,000, the affordability ratio is 7.5. This means the house price is around 7.5 times annual earnings.
Why This Calculator Is Useful for Home Buyers
The ONS house affordability calculator can help buyers look beyond asking prices. A home may seem cheaper in one area, but affordability depends on local earnings, mortgage costs, deposit size, travel costs and lifestyle needs.
This calculator is especially useful when you are:
- Comparing two or more locations before starting your property search
- Trying to understand whether an area is expensive compared with local income
- Thinking about relocating to a different town, city or region
- Checking whether house prices in an area may feel stretched
- Planning a first-time buyer budget
- Looking at long-term affordability before making an offer
Buyer tip: Do not use asking price alone to judge affordability. Always compare the property price with income, mortgage payments, deposit, moving costs, Stamp Duty, travel and future bills.
What the Calculator Can Help You Understand
| Buyer Question | How the Calculator Helps |
|---|---|
| Is this area expensive? | It helps show how local house prices compare with local earnings. |
| Which area looks more affordable? | You can compare different places and see how affordability changes by location. |
| Are local prices high compared with wages? | The affordability ratio can show whether prices are stretched compared with income. |
| Should I widen my search area? | If one area looks unaffordable, nearby areas may offer better value. |
| Is this useful before speaking to a mortgage adviser? | Yes. It can help you understand the area before getting mortgage affordability advice. |
What This Calculator Does Not Tell You
The calculator is useful, but it does not replace a full mortgage affordability check or professional advice. It gives a helpful view of local affordability, but it does not know your personal financial situation.
| Not Included | Why It Matters |
|---|---|
| Your deposit | A bigger deposit can improve mortgage options and reduce borrowing needs. |
| Your credit history | Lenders check your credit profile before approving a mortgage. |
| Mortgage interest rates | Monthly payments can change depending on interest rate and mortgage term. |
| Monthly spending | Childcare, loans, car finance, bills and regular commitments affect affordability. |
| Stamp Duty and buying costs | Legal fees, survey fees, moving costs and taxes affect your total budget. |
| Property condition | A cheaper home may still be expensive if it needs major repairs. |
| Future lifestyle costs | Transport, school travel, parking, energy bills and service charges can change affordability. |
Important: This calculator helps you understand area-level affordability. It does not confirm how much you personally can borrow.
How Buyers Should Use the Calculator
- Start by entering or selecting the area you are interested in.
- Review the house affordability results shown by the ONS calculator.
- Compare the area with nearby towns, boroughs or local authorities.
- Think about whether the area fits your income, deposit and mortgage plans.
- Check local sold prices on property portals and Land Registry data.
- Speak to a mortgage adviser or lender for your personal borrowing position.
- Use the result as one part of your property search, not the only decision point.
Practical tip: If an area looks expensive compared with earnings, do not automatically rule it out. Check property type, commute, schools, future growth, service charges and long-term resale demand.
House Affordability vs Mortgage Affordability
These two terms sound similar, but they are not the same.
| Type | What It Means | Who Uses It? |
|---|---|---|
| House affordability | Compares local house prices with local earnings or income. | Useful for buyers comparing areas and market conditions. |
| Mortgage affordability | Checks how much you personally may be able to borrow based on income, spending, deposit and credit profile. | Used by lenders and mortgage advisers. |
A location can look affordable on paper, but your personal mortgage affordability may still be limited by your deposit, income, credit score or monthly commitments.
Important Buyer Checks After Using the Calculator
| Check | Why It Matters | Done |
|---|---|---|
| Check your mortgage agreement in principle | This gives a better idea of your possible borrowing range. | |
| Compare sold prices nearby | Sold prices are often more useful than asking prices. | |
| Check total buying costs | Stamp Duty, solicitor fees, survey fees and moving costs affect the full budget. | |
| Review commute and transport costs | A cheaper house may cost more in travel time and travel money. | |
| Check property condition | Repairs can change whether a home is truly affordable. | |
| Speak to a mortgage adviser or lender | They can check your personal borrowing and monthly payment options. |
When This Calculator Is Most Helpful
The House Affordability Calculator is most helpful at the early stage of buying a home, especially before you become emotionally attached to a property.
- Before choosing your target area
- Before booking multiple viewings
- Before making an offer
- Before relocating to a new town or city
- Before comparing house prices across different areas
- Before deciding whether to stretch your budget
Buyer warning: A property can be affordable to buy but expensive to keep. Always consider mortgage payments, council tax, service charges, repairs, insurance, travel and energy bills.
Final Thoughts
The ONS House Affordability Calculator is a useful starting point for understanding how affordable homes may be in different areas. It helps buyers compare local house prices with earnings and think more carefully about where to search.
However, it should be used alongside mortgage advice, local sold price checks, viewing research, survey findings and a full buying cost budget.
Key takeaway: Use the calculator to understand the area, then speak to a mortgage adviser or lender to understand what is affordable for you personally.
