At the heart of householding spending is the budget.
The days of receiving a weekly pay packet with cash have disappeared into the mists of time.
Almost everyone gets paid by a bank transfer from their employer, pension or benefit agency.
From that amount, there will be certain deductions which will be set up by direct debit and other payment transactions.
Weekly food and household shopping will usually be paid for by card. It is very easy to overspend these items and simply lose track.
Other items also get tacked on such as subscriptions to entertainment and items for family. It is easy to do and there are no consequences at the point of purchase.
The downside is when bank statements come in showing every purchase and often the amount going out exceeds the amount going in.
An increasing number of people are deciding to economize by leaving the large deductions such as rent, mortgage etc. in place, discarding any unnecessary subscriptions, and lifting an amount of cash to cover food and household goods.
Only that money can be used. Once it runs out there is no more.
This method shows that it eliminates unnecessary items finding their way into a supermarket basket, and sticking to essentials.
This system can be widened of course.
It can also include putting cash aside for utilities, clothing, transport and leisure.
Traditionally weekly pay packet money was divided into rent, utilities, food/household and anything left was for saving.
It is a model which would be difficult to comprehend for people brought up on paying for everything by card, but it is a system which keeps a tight reign on budget and can work well.
