I've just been sitting here refining my Debt Dragon article so I've been thinking about credit and debts.
And it's only just dawned on me the whole interest free credit trap. I'd never considered this aspect and the companies motivation to offer it.
Hear me out...
You earn £30k gross, you take home £24549.36 a year after pension and tax/NI.
You want to buy something but can't afford it (no savings), but the company is offering 0% interest finance.
It's a kitchen, it's £4k, it's interest free credit for 2 years at £166.66 a month.
Fantastic!
But now, instead of having £2045.78 a month to live on, you only have £1870.12.
So now, you have less money to spend each month than you did before, even though the borrowing isn't costing you anything in interest.
But because you have less money, your budget is a bit tighter, so now you start buying other things on Klana to spread the cost.
But next month, even though they are both interest free and don't cost you anything, you have even less money to live on for the month.
So you have to buy the next thing on Klana to make it through the month.
Gradually your monthly income is being squeezed and squeezed and squeezed.
All these helpful companies allowing you to buy things interest free have gotten you into a tight little pickle because you've got to pay the money back.
So you're almost forced to take out a loan or a credit card to start being able to afford to live.
So they got you! You are desperate. You had to borrow money because your income that used to cover your life, now doesn't because you spent your future earnings before they were in the bank and you have to pay them back.
I'd always wondered why they did interest free, always thought it was just a way to help them sell more as a customer will always think 'it's not costing me anything'. (Well, that's what I would think).
Borrowing against a priceless antique or your house is one thing, but borrowing from your future earnings, when you could lose your job, is absolutely insane.
It's so much better for your budget and your sanity and your credit score, to save up for whatever you need and get second hand in the meantime.
Some facts: £10k loan over 5 years, currently about 6% = £194pm = £1661 interest paid in total
The UK is Klana's 3rd biggest market globally, with 11million active users in the last 12 months, average balance £150.
Klana makes most of its income from the retailers that offer their finance who pay them 2%-6% of the transaction fee. The retailer will obviously be putting up their costs to cover this. But offering the ability to pay over 3 or 4 months has seen sales increase by 40-45%, and returning customers up by about the same.
All this proves is the psychological way we think about money. We don't see a £100 hat if we only pay £33 a month. Another way the system is designed to get you to buy more, ergo, owe more of your future earnings.
Avoid at all costs. Buy things with your savings. Live within your means. Always ask yourself the ultimate question 'Do I want this item MORE than I want to meet my financial goals?'
