I have two daughters who live at home with me who are both university students. They both work part-time and pay me $50 a week each for everything. (And I mean absolutely everything!) I had begun to get sick and tired of their wasteful habits! I would find half eaten muesli bars lying around, week-old uneaten fruit, discarded shampoo bottles and toothpaste tubes with enough in the base for three or four more uses, soap in the bin which still had plenty of use left in it and the list goes on! Quite frankly, I'd had enough! I told them to keep their $50 a week and instead they could buy everything for themselves (snacks, lunches, toiletries and so on). I would provide their one evening meal and that was it. I even made them buy their own toilet paper. Well after two weeks they have decided to mend their ways! They just did not realise the costs involved in running a household and admitted they had taken things for granted. I only wish I had done it much sooner, for their benefit and also mine! One daughter can only afford to give me $50 still and her older sister has increased her amount to $70. However, I think things around here are going to be very different from now on as my Sad Sallys strive to become more like Happy Hanna!

I have saved $50 in virtual coins in just a few weeks, since I started using my online money jar! I like the idea of emptying out my purse at the end of every day and placing loose change into a money jar to help me to save. The trouble is, I don't really carry any cash on me any more! Whenever I need to buy something I transfer the exact amount onto my debit card then go out and buy it. This ensures I never have excess cash to spend but it makes it difficult to save loose change. So I came up with this idea. Every time I log on to Internet banking I check all my savings accounts and transfer all the cents into a separate savings account called my 'e-Money Jar'. It's working perfectly and is amazing how quickly those few cents soon mount up!

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

I can hardly believe it but we have an extra $2000 sitting in our savings account! I have been a stay at home mum for 18 months. My husband earns a slightly above average salary, which allows me to stay at home with our son. We have a modest home, with modest furnishings and modest tastes. We haven't really had a financial plan since we got married two and a half years ago and have just been cruising along, saving a bit some months and spending it other months.

When I first left work I had full intentions of making a budget, planning our meals, organising our lives and generally being on the ball with our finances. Each month when pay day rolled around, I would say 'this is the month where I get organised!' But it never happened. I am the first to admit that I have been lazy, unmotivated, complacent and ostrich-like. I have been a member of Simple Savings for over a year and always thought we were doing OK and didn't really need to know all these ways to save money. I had heard of the $21 Challenge but wasn't really motivated to try it and we were ticking along as usual - until last month.

With baby number two arriving in three months we needed extra storage space so we extended our garage to make room for all our stuff. This extension made a dent in the savings account which although we knew it would, was quite depressing to see the balance dropping and dropping and not going back up. Lo and behold, motivation began creeping in!

I downloaded all our bank transactions for the month and was horrified to find that I had spent an average of nearly $260 per week on groceries for two adults and one toddler. There were lots of other things I was also horrified to see but I started with the groceries as it seemed easiest. Motivation knocked harder. I decided to take charge!

I read the first two chapters of the $21 Challenge on the website, put a copy of the book on my library request list and did a stocktake of my pantry, fridge and freezer. Imagine my shock when I discovered I had enough ingredients to plan meals for the next 19 days! That's not counting meals like scrambled eggs, pumpkin soup and the emergency baked beans on toast. We had enough food in the house to live on for over three weeks! We just needed fresh fruit and veges and that was about it. I didn't quite make $21 but my first grocery shop after doing the stocktake came to $61, down from $258 per week the previous month.

From then on I watched the bank account like a hawk and knew where every cent went. In previous months when the bank account got low, I would simply pull out the credit card and pay it off on pay day but not this month! This month it stayed in my wallet.

It's pay day again tomorrow and guess what? I have spent an average of $160 per week on groceries, saving us nearly $100 per week. By being aware and thinking to myself 'do I really need that?' and deciding 'no', the savings account has increased by a whopping $2250! That figure makes me weak at the knees! I can’t honestly say where the money has been going before now. We don’t have the latest gadgets, appliances or clothing. I am truly at a loss BUT I have to say I'm pretty proud of myself right now! At the same time, I feel a bit sick that I didn't do this 18 months ago, or even 12 or 6 months ago, but I've done it now. I am motivated to change my ways. I have goals. I have the energy to do this and I have Simple Savings to thank for giving me the tools to continue saving. THANK YOU!

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.

When you are going out for a picnic or taking lunch to work or school, use cloth to wrap the sandwiches. This is much better than cling wrap or foil because it's cheap and reusable. I use tea towels, napkins and chopped up table cloths to wrap my sandwiches. The sandwiches stay fresh and when I've finished, I just shake off the crumbs and take the cloth home to be washed and used again.

There is something pleasantly old-fashioned about this method - and just think of all that plastic not going into landfill.

Our wonderful daughter is a saver on the grandest scale. At 29 years old and earning a modest wage, she is building her first mortgage free home on five acres; as well as flying out to Bali for a holiday! She has had several serious health problems but is amazing in her efforts to follow her plan, thanks to the support of her equally admirable husband. Their two horses and two dogs are greatly loved and their lifestyle is totally free of unnecessary expenditure. They own their block of land, furniture and vehicles as they need them to drive to work.

To save rent while rebuilding they bought a duplex then removed junk, scrubbed, painted and renovated by finding the best way to build fences, roof a pergola and fix the faults. Meanwhile they have fenced their own block of land, installed gates, had a bore sunk, built open stables themselves with salvaged material and negotiated the big expenses of shed, driveway and site costs.

They are not without experience as she purchased her first property at 19, a unit which she and her father gutted and renovated. Her husband joined in and renovated a property, then they renovated a joint property before they purchased five acres, built a house and developed it for resale so that they could buy their current land. Recycling has included rescuing old baths for horse water troughs, finding a kitchen sink for a fish cleaning bench and rebuilding an old horse float. They planted and watered tube stock trees, had family members grow cuttings and even used the horses to mow the lawns. In fact one horse was purchased for the knacker's fee and the other was free.

No, she hasn't benefitted from a first home buyer's grant as she was too young at the time of her first unit, or from family gifts. Just planning, following her dream and sticking to the budget. It works!

I recently noticed my elderly neighbour was unwell and no longer able to drive or leave the house; relying on taxi services to deliver food (often expensive pre-packaged items), or he would have home delivered takeaways. Being a fussy eater, he was reluctant to consider 'Meals on Wheels', so I volunteered to shop for him and cook him three different meals a week. Each week he gives me enough money to cover the costs of his meals (soups/stews/freezable casseroles) and I make up bulk amounts of each dish. I deliver half to him and keep half for myself, as suggested by him for payment. Not only is he saving money on taxis and home delivery, but he is eating healthy food and my family is also provided with three meals a week as a bonus for giving up a little of my time. Often cooking for one is not inviting, but cooking for others encourages healthier eating habits and helps regain social contact. Often a lonely person will gain a new lease on life to boot. A great savings all round, and using recipes from the Vault saves me even more!

We decided to get rid of the $96,000 mortgage on our home within three years. The massive load of interest we would pay to the bank was over the top and we felt that the bank owned us. The entire family bought into the project one hundred percent.

1) We replaced the nice modern cars with older, less costly ones. The net difference and any savings we had and $700 from a garage sale were paid off the mortgage.

2) We agreed to budget as if we were in a life and death war and the war had to be won in three years. I developed an Excel budget spreadsheet and we tweaked the numbers until we had a 'do-able' weekly saving of $220 extra to pay off the mortgage. Clothes purchases would be done exclusively at 'Harrods', our Salvation Army shop, until the war was over.

We decided to run any item not budgeted for over three 'hurdles'.

The first hurdle was 'could it shorten the mortgage war?'

The second hurdle was 'is it a health issue?' and if so what was the least-cost workable solution?

The third hurdle was 'could it wait until the end of the three years?'

3) As time progressed we became pretty smart at reassigning money to reward ourselves for enduring the war. This meant we could have a low cost take away sometimes, or spend on an out of budget item we had set our hearts on.

It took nearly four years to knock off the mortgage. Yes, we won the war a little later than hoped, but we won. If it had taken eight or nine years to win, it would still have been worth it.

The legacy of our war against the mortgage is that we have developed great money saving skills for life. And life is great.
