How Much Loan Can I Afford? A Step-by-Step EMI Guide (UK & Europe 2026)
.webp "How Much Loan Can I Afford? A Step-by-Step EMI Guide (UK & Europe 2026)")
"How much can I borrow?"
Wrong question. I'll explain why in a second, but first — almost everyone asks this, and almost everyone gets an answer that doesn't actually help them.
Here's the thing. Lenders will happily tell you the maximum they're willing to give you. That number is based on their risk model — basically, how likely are you to default. It has very little to do with whether the monthly payment will actually feel okay to live with.
"Maximum approved" and "comfortably affordable" are two completely different numbers. Nobody tells you that upfront. So this guide does — step by step, with real figures, no jargon.
Why "You're Approved For £15,000" Doesn't Mean You Should Take £15,000
Lender affordability checks generally allow a fairly large chunk of your disposable income to go toward debt. Sounds reasonable on paper.
But "disposable income" on a spreadsheet and "money I actually have left at the end of the month" — these are not the same thing. Not even close, honestly. Lenders don't always account for irregular costs, savings goals, or just... wanting some breathing room. Their model answers one question: will you probably default? That's a much lower bar than "will this feel fine every month."
This is exactly how people end up loan poor. Approved for an amount that fits the lender's model perfectly, and yet every month feels tighter than it used to.
The 35% Rule (And When You Should Go Way Below It)
Most UK and European lenders use roughly the same guideline: keep total monthly debt repayments under 35% of your net (take-home) income. That's everything combined — the new loan, existing loans, credit card minimums, car finance, all of it.
| Net Monthly Income | 35% Maximum (All Debt) | If You Have No Other Debt |
|---|---|---|
| £1,500 | £525 | £525 available for new loan |
| £2,000 | £700 | £700 available for new loan |
| £2,500 | £875 | £875 available for new loan |
| £3,000 | £1,050 | £1,050 available for new loan |
| £4,000 | £1,400 | £1,400 available for new loan |
Now — and this is the bit most articles skip — 35% is a ceiling, not a target. It's the absolute maximum lenders will tolerate, not what you should actually aim for.
If you're already comfortable, with decent savings sitting in the background, sure, 35% might be fine. But if money already feels a bit tight before adding this loan? Aim for 20-25% instead. That spreadsheet doesn't know your life. You do.
Step by Step — Working Out Your Actual Number
Okay, here's the process. Grab a notes app. This takes maybe 10 minutes, and it's genuinely worth doing properly rather than skimming.
A Worked Example
Let's make this real. Someone earning £2,400 net a month in the UK. Pretty average situation.
| Item | Monthly Amount |
|---|---|
| Net income | £2,400 |
| Rent | £800 |
| Existing car finance | £180 |
| Utilities, phone, internet | £150 |
| Groceries | £280 |
| Transport (non-car) | £60 |
| Total committed | £1,470 |
| Left over | £930 |
£930 left at the end of the month. Sounds like a lot. Does this person commit all of it to a new loan?
No. Obviously not — that leaves nothing for savings, for going out occasionally, for the boiler that inevitably breaks at the worst time. Around £250-300 a month toward a new loan is far more sensible. Here's what that actually buys:
| Monthly Payment | APR | Tenure | Loan Amount You Could Take |
|---|---|---|---|
| £250 | 8% APR | 3 years | ~£7,900 |
| £250 | 8% APR | 5 years | ~£12,400 |
| £300 | 8% APR | 3 years | ~£9,500 |
| £300 | 8% APR | 5 years | ~£14,900 |
So somewhere between roughly £7,900 and £14,900, depending on tenure, is genuinely comfortable for this person. If a lender offered them £20,000? That pushes the monthly payment well past their actual comfort zone — even if the lender's model says it's fine.
Try different loan amounts and tenures. See exactly what monthly payment each one creates, and work backwards from your budget.
Three Things That Can Shift the Numbers
Stretching the Tenure
If your dream amount comes in slightly above your comfort zone, adding 12 months to the tenure often pulls it back into range. Worth knowing — but as we covered in our EMI guide, this adds to the total interest. It's a trade-off. Not a free lunch.
Just... Borrowing Less
Sometimes the boring answer is the right one. Financing a renovation, a car, a wedding — does a slightly scaled-back version still get the job done? The gap between £15,000 and £12,000 might be the difference between "fine" and "stressful," every single month for years.
Fixing Your Rate Before You Apply
Lower APR = more loan for the same monthly payment. If your credit sits in the "fair" range, a few months of work — covered in our UK credit score guide — could move you from 12% to 8% APR. Same monthly payment, meaningfully more borrowing power.
People Also Ask
How much loan can I get based on my salary?
There's no universal multiple of salary that applies to everyone. It comes down to your existing debts, essential expenses, and the lender's specific model. As a starting point — total monthly debt repayments, including the new loan, should stay under 35% of net monthly income. Use the EMI Calculator to turn that monthly figure into an actual loan amount at your expected APR and tenure.
What percentage of income should go to loan repayments?
35% of net monthly income is the ceiling most UK and European lenders use. Again — ceiling, not target. If savings are limited or income is irregular, 20-25% gives you noticeably more breathing room and a lot less stress if something changes.
Does a longer loan term mean I can afford more?
In terms of monthly payment, yes — spreading the same amount over more months lowers each individual payment. But the total interest goes up, sometimes by a fair amount. Use a longer term because you genuinely need the lower payment, not just because the option exists.
Should I borrow the maximum a lender approves me for?
No. That number reflects their risk assessment — not whether the resulting payment fits comfortably into your actual life. Work out your own affordable amount first, based on your real budget, before applying anywhere. If a lender offers more than that, it's perfectly fine to just... not take it.
What if there's barely anything left over each month?
Then honestly, this might not be the right moment for a new loan — regardless of what you'd be approved for. Worth asking whether the expense can wait while you build some breathing room, whether existing costs can be trimmed, or whether a smaller version of whatever you need would work for now.
Bottom Line
The question was never "how much can I borrow." It's "how much can I borrow without my month feeling different."
Work out what's actually left over, decide how much of it you're comfortable committing, then use the EMI Calculator to turn that into a loan amount. Do this first. Before the offers, before the "you're approved for" emails.
Ten minutes. That's genuinely all it takes — and it's the difference between a loan that fits your life and one that quietly reshapes it.
