There is no one-size-fits-all answer to how much of your paycheck you should save each month, as it depends on your individual financial situation and goals. However, there are a few general guidelines you can follow.

One popular rule of thumb is to save at least 20% of your income each month. This includes saving for both short-term goals, such as an emergency fund, and long-term goals, such as retirement.

Another popular rule of thumb is to save at least 15% of your income if you are starting to save for retirement in your 20s or 30s and increase the percentage as you get closer to retirement.

A good way to start saving money is to set a budget and determine how much you can save every month. Be realistic with your budget, and make sure you're saving enough to meet your short-term and long-term financial goals, including paying off any high-interest debt and saving for retirement.

It's important to keep in mind that saving is a journey, you don't have to start with 20% or even 15% if that’s not possible, but it's important to start somewhere and gradually increase your savings over time.

Ultimately, the most important thing is to start saving as soon as possible, and to make it a consistent habit. Even if you can only save a small percentage of your paycheck at first, it's better than nothing and as you progress, you can adjust it to a higher percentage.
