← Money Foundations · lesson 5 of 10
By the end of this one you'll know what saving is for, what investing is for, and why they're two different jobs and not two flavors of the same thing.
Saving is grain in the bin, money kept somewhere safe and easy to grab, like a savings account, because there's always a week the van breaks or the water heater dies. Investing is planting seed, using money to buy a piece of something, like a share, which is a small slice of a real business, hoping it grows into more over the years. Grain doesn't grow while it sits in the bin, but it's right there the day you need it, and that's the entire point of the bin. Seed can grow into a whole field, but it can also get hit by drought, and you can't yank it back out of the ground in January because the kids need shoes. So saved money keeps its number and grows slowly, while invested money can grow bigger or shrink, and nobody on earth can promise which. The mess starts when folks swap the two jobs. Some plant their grain, meaning they put emergency money somewhere it can shrink. Some pour seed into the bin, meaning money they won't need for decades sits in a drawer while inflation nibbles at it. Two jobs, two tools.
Same lesson, told by a hundred dollar bill. Tap to walk it one step at a time.
In this example, 100 dollars in a savings account paying 4 percent APY, which just means it grows about 4 percent over a full year, becomes about 104 dollars in a year and you can grab it any day you want.
The same 100 put into a broad stock fund, a basket holding little pieces of hundreds of companies, has no promised number, in one example year it grows to 115 and in another it drops to 85, and history has real years like both.
Either way the fund itself keeps a small yearly fee, in this example about 50 cents of that 100.
It's Friday and this paycheck has 150 dollars of overtime on it, real extra money for once. At shift change a coworker mentions she finally started investing, and your savings account is sitting at almost nothing.
Pick your move. Then peek at the other roads if you're curious.
Saving and investing are two different jobs on two different calendars, one holds money for this year's storm and one plants money for a decade away.
