They say you need to spend money to make money. You can also spend money to save money.
Here are seven things you can buy today that could end up saving you money in the future.
1. Dash cam
If you've ever been a car accident, you can probably see the appeal of a dash cam that records everything that happens in front of your car. A recording can help show your insurance company and the police who was really at fault. Dash cams start at about $65.
2. Heated mattress pad
You can save up to 10% on heating and cooling costs by turning your thermostat back 7 to 10 degrees a day, the Department of Energy says. One way to stay warm in the winter without turning up the heat is by purchasing heated bedding. Electric blankets and heated mattress pads consume very little electricity, according to tests by The Wirecutter, so using one should result in a net savings on your utility bills over time. A heated mattress pad starts at about $90.
3. Alarm clock
Sure, you can use your smartphone as an alarm clock. But having your smartphone near your bed might not be the best idea. The blue light it emits suppresses a hormone that helps you sleep, making it tougher to doze off and leaving you less refreshed in the morning.
Buying a separate alarm clock can keep your phone out of your bedroom, end your late-night Twitter habit, and get you up on time to be your best at work. Alarm clocks are super cheap too.
4. Knife sharpener
A dull blade can cost you — a finger. All knives eventually get dull, even fancy, expensive knives. To protect your investment and yourself, a knife sharpener is a necessity. You can buy a good sharpener starting at about $40.
5. Surge protector
You spend a lot on your electronics. A surge protector is like an insurance policy. It keeps them from getting fried in the event of a power surge due to a storm or some other electrical problem. You can get a one-outlet surge protector for as little as $10, but you'll pay more to protect all your devices.
If you need to dress up for work, and especially if you have to travel for business, a steamer is a good investment. They can quickly get the wrinkles out of your clothes, getting you ready for a job interview or presentation in a snap. A travel steamer goes for about $20, and can save you on trips to the dry cleaner.
7. Streaming device
Paying for cable is over. A streaming device like Roku or Apple TV gives your TV access to an endless supply of media from Netflix to HBO Now. You can haggle over your cable bill every year, or you can just cut the cord. A basic Roku stick starts at $40.
