We've calculated just how much the median mortgage in regional Australia is predicted to rise by the end of the year - and just how much that adds up in takeaway coffees. And for caffeine lovers it's not pretty.

Assuming the cash rate reaches 3.1 per cent by the end of 2022, it would take a huge 177 takeaway coffees per month - 2.9 each per day for a couple - to cover the extra cost for variable mortgage holders in Canberra.

This shocking figure is based on someone with a loan of $750,054 per cent of the current median house price for Canberra of $937,568.

The hike in interest rate is based on Westpac's forecast of the official interest rate rising 1.35 per cent to 3.1 per cent by December 2022 and that full rate increase being passed on by banks, resulting in a variable mortgage rate of 5.8 per cent.

Luckily for those who rely on a morning macchiato, there's other ways to stay in the (long) black.

Finance guru and Canstar's editor-at-large Effie Zahos has seven easy tips for homeowners looking to clean up their budget.

Staying on top of your mortgage is the best way to, well, stay on top of your mortgage.

It's worth checking to see if you can snag a better deal, especially if your loan has rolled over or is near completion.

How many streaming services is too many?

By cutting out just one per year you could add about 30 coffees back into the budget.

EZ says: Play the game. Watch what you want, then unsubscribe and sign up somewhere else. Use the free trial periods. It doesn't cost anything to swap and change.

Groceries are essential but $12 lettuces are a luxury.

Shopping at fresh food markets and stocking up on 'specials' at the supermarket are easy ways to save.

EZ says: There are so many comparison apps to help you at the grocery stores which is amazing. If you're shopping online use filters to sort by unit pricing ... sometimes you think big is better, but not nececeasarily.

Do you have a car you never use chewing up money on insurance, petrol or depreciation?

Selling items you don't use is easy money, and they'll almost certainly be worth more now than in a year's time.

EZ says: The second hand economy is doing extremely well. Look around your house - I always say you should be able to find 10 items in your home you can sell.

If you have a ute and the will to lift heavy objects you're a millionaire waiting to happen on Airtasker.

Removalists, handymen, cleaners and lawn mowers are all in high demand, and a spare room in your house could be an ideal income opportunity in a tight rental market.

EZ says: The number of people listing tasks on Airtasker has exploded - have a look at what skillset you have and what income you could earn from it.

Entertainment and luxury items can be the easiest spendings to shed.

Taking the time to search out the best-value providers can free up space in the budget.

EZ says: Swapping and saving on your regular bills can bring you in about $600 a month - that's some much-needed money to be redirected to your home loan.
