How much of your income are you keeping?

Your savings rate is the share of your income you keep instead of spend. It’s the single number that most shapes your financial future. Work out your true rate, including what goes to retirement before your paycheck, and see how many working years it points to.

Step 1 · Your monthly income

What lands in your bank account after taxes and deductions. Include a partner if you share finances.
Monthly 401(k) or 403(b) money taken before your paycheck, plus any employer match. 0 if none.

Step 2 · What you save

Monthly transfers to savings, investments or an IRA, plus extra debt payments beyond the minimums.

How this calculator works

Savings rate = (pre-tax contributions + money saved) ÷ (take-home pay + pre-tax contributions)

Money that goes to retirement before your paycheck is income you’ve kept, so it counts on both sides. On $5,000 take-home, with $400 going to a 401(k) and $500 moved to savings, you keep $900 of $5,400: a savings rate of about 17%.

Under 10% leaves you exposed to surprises. 10–20% is a solid baseline, roughly what many retirement planners suggest. 20% or more builds real momentum.

A higher rate helps twice: you invest more, and you learn to live on less, so you need a smaller nest egg. The working-years estimate assumes investments earn 5% a year after inflation and that you reach independence at 25 times your yearly spending (the 4% rule). It’s a planning yardstick, not a promise.

Words you’ll see

Savings rate
The share of your income you keep instead of spend, counting retirement contributions and extra debt payments.
Take-home pay
Your pay after taxes and payroll deductions: what actually reaches your bank account.
Employer match
Money your employer adds to your retirement account when you contribute. Capturing the full match is usually the best return available.
Financial independence
Having enough invested that its returns can cover your spending, so working becomes a choice.
4% rule
A rule of thumb that you can withdraw about 4% of a diversified portfolio in the first year of retirement, rising with inflation, with a low risk of running out over 30 years. It’s why the target is 25 times yearly spending.

Common questions

How do I calculate my savings rate?

Add your pre-tax retirement contributions to the money you save from your paycheck, then divide by your take-home pay plus those same contributions. On $5,000 take-home, with $400 going to a 401(k) and $500 moved to savings, you keep $900 of $5,400, a savings rate of about 17%.

What is a good savings rate?

Under 10% leaves little room for surprises, 10 to 20% is a solid baseline, and 20% or more builds real momentum. Fidelity's rule of thumb is to save at least 15% of pre-tax income each year for retirement, counting any employer match.

How long will it take to reach financial independence at my savings rate?

Starting from zero, with investments earning 5% a year after inflation and a target of 25 times your yearly spending, a 10% savings rate takes about 52 years, 20% about 37 years and 50% about 17 years. Money you have already invested shortens the timeline.

Should 401(k) contributions count in my savings rate?

Yes. Pre-tax 401(k) or 403(b) contributions and any employer match are income you have kept, so count them in both your savings and your income. Leaving them out makes your savings rate look lower than it really is.
