What if you could lower your grocery bill without giving up the things you love, fight inflation, and have some money left at the end of the month? Sounds too good to be true? It’s not. It’s the Half Rule. This means cutting the amount of product you use in half and seeing what happens.
Truth is, most of us probably use too much of the things we love. Here are several reasons why:
Manufacturers often ask you to use more of the product than you need.
You’ve probably gotten used to using a certain amount of a product;
And finally, product inflation. Specifically, you might think that if you get pleasure out of something, you might need to use more of it. For instance, why get a tall vanilla latte when you can get a grande, right? But ask yourself: Is it really that much better?
To this end, here are some things you can easily use half of and never miss the other half:
Shampoo. Try using half the amount and adding more water, especially if it’s concentrated.
Laundry detergent. Try a half cup. A little goes a long way, especially if it’s a small load.
Dryer sheets. These are so easy to tear in half.
Cooking oil. Use an oil mister instead of pouring it into your pan or skillet.
Restaurant meals. Eat half or a third and save the rest for another meal. Or better yet, split a meal with your partner, friend or work colleague. Bonus: you’ll also save calories.
Bagels. Just eat half! Save the other half for your next snack or breakfast.
Starbucks order. Try a tall. Or if you get a vente, try a grande. Give it a whirl. See what happens.
Glass stovetop cleaner. If you use less, you might have fewer streaks.
Tape. When you’re wrapping gifts, give string a try.
When you change a few things here and there, over time, you’ll really see the difference in your bank account. Also, imagine how nice it’ll feel not to have to buy these items so often. That’s a big change in spending.
The Half Rule is not for everything. While it works on so many things, there are some things you cannot to apply it to – like filling up your gas tank or cutting a prescription in half. Never do that.
Overall, it’s a good rule. And when you’re persistent over time, you’ll start to develop a habit – one that will help you see a difference quickly and save you money in the long run. It’s a ripple effect that might expand into other areas of your life. In sum, the Half Rule is so effective, you just might go all in – and stay there.
