David Koch says he can help you make $10k in just 20 days.

David Koch reckons he could make you an extra $10,000 in just 20 days.

With absolutely no involvement from the Cash Cow at all.

The Sunrisehost, who started his career as a financial journalist and has become somewhat of a personal finance guru, says it’s really quite simple actually.

It all comes down to three easy steps: sell, earn, and save.

You see, all you have to do is pick up a “side hustle” in your spare time, sell your unwanted clutter, and look at ways to slash your bills.

Which doesn’t seem exactlygroundbreaking.I’m fairly certain that’s the basic premise of saving money and has been… forever.

But look, I’m not going to saynoto an extra $500 a day. So Kochie, please, how do I make it rain money?

Well, on Kochie’s new programHow To Make $10k in 20 days,which premiered on Channel 7 on Wednesday night, he challenged two very different couples to save (surprise, surprise) $10k in less than three weeks, using his tips and advice.

“Every day I talk to ordinary Aussies who tell me how hard they work for every single dollar, but a quick injection of cash would really help them out,” he said.

“Most think it’s impossible, but there is a way to get ahead and I’m looking forward to showing Australia how to do it.”

Taking up Koch’s “sprint saving” challenge were Gold Coast couple Jana and Tim, who earn a combined income of $150,000 year, and Sydney parents-of-three Rebecca and Mick who rely on $83,000 a year.

It was immediately clear sacrifices needed to be made.

Tim and Jana are used to spending around $300 a week eating out, but for three weeks, they decided to forgo their favourite brunch meal, Eggs Benny, for Vegemite on toast and to their utter distaste, instant coffee, at home.

They also rented out their three-bedroom house on Airbnb, picked up odd jobs and Tim sold his boat for around $5k. The couple ended up saving $10,1117 – which is incredible... if you had an old tinnie just lying around that is. We all have that, right? Okay, glad we cleared that up.

It was... unsurprisingly... a tad harder for Rebecca and Mick. After selling literally every unwanted item they own, picking up jobs via Airtasker, and buying bulk groceries to last the three weeks, the couple ended up saving $7253.

Although it didn't reach the nice and round magical number of $10k, it's an impressive amount none the less, but involved an intense regime that did not seem... sustainable.

Many viewers were also left questioning how relevant the advice was to ordinary Aussies wanting to realistically save money.

Watching ‘How to make 10k in 20 days’ and the couples have combined incomes of $83k & $150k. I reckon anyone could find $10k with those incomes! ????

I watched about 5 minutes of it. It’s basically work yourself arse off, spend no money, and sell stuff. Not rocket science is it. Plus most of us earn less than that and we do this all the time now.

Surely the idea of halving your grocery bill is to still eat nutritiously while not starving yourself?

The couples chosen for this show are highly selected like the family with $$$ worth of baby products and a couple with high value clothing and expensive surfboards. Not helpful for the average #Australian. Not to mention the family’s caravan and the couple’s brothers’ bus.

We'll just have to wait and see if next episode actually proveshelpful.¯\_(ツ)_/¯.

David Koch reckons he can make you $10k in 20 days and Kochie pls, there's a clear problem.
