Boomer vs Gen Z House Price Calculator
See how much harder your generation works to own the same home
In 1979, a Baby Boomer paid £775 a month on their first mortgage. Today, Gen Z pays £1,739 for the same milestone. That’s not just inflation—it’s a £97,000 gap over 15 years. Your paycheck hasn’t doubled, but your mortgage burden has. This shows you exactly how much harder you’re working for the same dream your parents had at your age.
What the Numbers Actually Mean
Every figure here comes from real UK mortgage data, not guesswork. When you enter your birth year and property price, the system compares what someone from your generation typically pays against what Baby Boomers paid when they were the same age—adjusted for inflation so it’s apples to apples.
Monthly payment uses standard mortgage formulas: your loan amount (property price minus deposit) multiplied by your interest rate over 30 years. The comparison pulls historical interest rates for each generation—Boomers averaged 13.5% but paid £74,000 for a house, while Gen Z faces 5.5% on £293,399 properties. Total 15-year cost includes all payments made in the first half of a typical 30-year mortgage.

Limitation: This uses average data. Regional differences matter—London deposits are £110,716 vs £26,859 in Wales. Your specific mortgage deal, credit score, and lender will affect your actual numbers.
The £97,000 Question
House prices have climbed 580% since 1979, but wages only doubled. A Baby Boomer buying their first home needed to save one-third of their £15,034 annual salary for a deposit—about £5,000. Today’s first-time buyer earns £37,430 but needs £61,090 upfront. That deposit alone is 1.6 times your yearly income.
It gets worse when you factor in rent. Average monthly rent jumped from £1,025 to £1,343 between 2019 and 2024—a 31% spike in five years. If you’re paying average rent on an average salary, you have roughly £1,150 left each month for bills, food, transport, and trying to save that £61,090 deposit. At that rate, saving takes 53 months without spending a penny on anything else.
Gen Z mortgage holders pay £104,000 in their first five years compared to Baby Boomers’ £46,500. That’s £57,500 more—enough to buy a decent car and take 10 holidays. And here’s the kicker: 58% of Gen Z’s house price growth over those five years goes straight to mortgage interest, not building equity. Boomers only lost 31% to interest thanks to rapid house price growth in the 1980s.
Real People, Real Numbers
Sarah, 27, Manchester
Sarah works in digital marketing earning £32,000. Her monthly mortgage payment is £1,131. A Baby Boomer buying the same property at 27 in 1978 would have paid £687 monthly (adjusted for inflation). Over 15 years, Sarah will pay £203,580 while her Boomer counterpart paid £123,660—a £79,920 difference. That extra cost equals nearly 2.5 years of her gross salary.
James, 33, London
James is a software engineer who saved aggressively for eight years. His monthly payment is £2,128. He’s paying 38% of his £82,000 salary toward housing. His parents bought their first London home in 1989 for £95,000 with a 10% deposit, paying £1,050 monthly. Even accounting for their 12% interest rate and inflation, James pays £428,160 over 15 years versus his parents’ £189,000—a gap of £239,160.
Emily, 25, Birmingham
Emily bought through a Help to Buy scheme as a teacher earning £28,500. Her 5% deposit was the minimum allowed, pushing her monthly payment to £1,182. Over five years, she’ll pay £70,920 total—but only £12,450 goes toward the principal. The rest is interest and fees. If house prices stay flat or fall, she could be trapped in negative equity, unable to move or sell without taking a loss.

Regional Reality Check
| Region | First-Time Buyer Age | Average Deposit | Average Property Price |
|---|---|---|---|
| London | 34 years, 1 month | £110,716 | £462,694 |
| South East | 34 years, 4 months | £63,470 | £321,598 |
| North West | 31 years | £37,221 | £216,412 |
| Scotland | 30 years, 11 months | £44,825 | £216,270 |
| Wales | 31 years, 11 months | £26,859 | £191,284 |
Location determines whether homeownership feels remotely achievable. A 25-year-old in Wales needs to save £26,859—doable in 3-4 years with discipline. That same person in London needs £110,716, which takes 8-10 years even with a £40,000 salary and minimal spending. By the time they’ve saved enough, house prices have likely risen another 15-20%.
FAQs
Why do Gen Z pay so much more than Boomers if interest rates are lower?
House prices. Boomers bought homes for £74,000 on average (in today’s money) even with 13.5% interest rates. Gen Z buys at £293,399 with 5.5% rates. The loan amount is four times bigger, which overwhelms the interest rate advantage. A 5.5% rate on £263,699 costs more monthly than a 13.5% rate on £66,600.
Are these numbers adjusted for inflation?
Yes. Every historical figure uses 2024 prices so comparisons are fair. When we say Boomers paid £775 monthly, that’s what their 1979 payment would buy in today’s economy. Without adjustment, their actual 1979 payment was around £140, which would be misleading to compare directly.
Does this account for salary differences between generations?
Partially. Average wages in 1979 were £15,034 (adjusted to today), and now they’re £37,430—a 149% increase. House prices went up 580% in the same period. So yes, wages rose, but housing costs rose nearly four times faster. The ratio of house price to salary was 4:1 for Boomers and is now 8:1 for Gen Z.
What if I have a different deposit percentage?
Deposit size changes everything. A 5% deposit on a £250,000 property means borrowing £237,500. A 20% deposit drops that to £200,000, saving you roughly £250 monthly and £45,000 over 15 years. But saving from 5% to 20% takes an extra £37,500 upfront—which is 3-5 years of saving for most first-time buyers.
Why does so much of my payment go to interest instead of equity?
Mortgage amortization. Early payments are mostly interest because you owe the full principal. If you borrow £250,000 at 5.5%, your first month’s interest alone is £1,146. Your £1,500 payment only puts £354 toward the actual loan. This flips over time—by year 20, most of each payment reduces the principal. Gen Z faces this worse than Boomers because higher house prices mean larger loans and more interest.
Is it even worth buying anymore?
Depends on your situation. Renting costs £1,343 monthly on average with zero equity gained—£241,740 over 15 years that’s gone forever. Owning costs more upfront and monthly, but you build equity. If house prices rise just 2% annually, your £250,000 home becomes £336,000 in 15 years. But if prices fall or stay flat (like they did for 2020 buyers), you could lose money or get trapped. There’s no universal answer.
What’s the best way to save for a deposit faster?
Lifetime ISAs give you a 25% government bonus (up to £1,000 per year) if you’re a first-time buyer. Opening one at 18 and maxing it out annually gets you to £33,000 plus bonuses by 25. Beyond that: reduce rent by house-sharing, automate savings the day you get paid, avoid lifestyle inflation when you get raises, and consider moving to a cheaper region if your job allows remote work.
Will house prices ever become affordable again?
Not likely through price drops. A 30% crash would wipe out equity for millions of existing owners, causing economic chaos. More probable: wages slowly catch up over decades, or interest rates drop significantly. Some experts suggest the Bank of England should target house price growth as part of inflation control—capping annual increases at 2-3% while wages grow 4-5%. But that requires political will that hasn’t materialized yet.
