Experts say you don't need $1 million to retire comfortably.

Instead, you should aim to save 75% to 85% of your pre-retirement income in retirement.

This is because you're likely to live longer than the average life expectancy, and your expenses may increase in retirement.

You should also factor in potential sources of income in retirement, such as Social Security, pensions, and rental income.

It's important to develop a retirement plan early so you can save enough money.

Consider contributing to a 401(k) or IRA, which offer tax advantages.

If you have an employer-sponsored 401(k) plan, see if your employer offers a matching contribution.

Invest your retirement savings wisely so that your money can grow over time.
