I have a friend, let’s call him "High-Income Harry." Harry makes $325,000 a year. He drives a brand new luxury SUV, lives in a massive house, and vacations in the Maldives. He also spends $250,000 a year.
I have another friend, "Teacher Tina." Tina makes $50,000 a year. She drives a ten-year-old Honda, lives in a modest apartment, and vacations at national parks. She spends $25,000 a year.
Who is going to retire first?
If you said Harry, you are wrong. Harry is a slave to his paycheck. If he loses his job, he is broke in two weeks. He can never stop working because his lifestyle demands a quarter-million dollars every single year to sustain. He has virtually nothing left to save after paying his high income taxes.
Tina? Tina is free. She saves 50% of her income. For every year she works, she buys a year of freedom. She will likely retire in her 40s, while Harry will be grinding away at his desk until he’s 70, wondering where all the money went.
This is the secret that Wall Street doesn't want you to know. Your income doesn't determine your retirement date. Your savings rate does.
The Shockingly Simple Math
Retirement isn't an age. It’s a math problem. And the math is surprisingly simple.
It all boils down to one number: What percentage of your take-home pay do you save?
- 0% Savings Rate: You can never retire. You are working until you die (or until Social Security kicks in, which might be a grim existence).
- 10% Savings Rate: It will take you roughly 51 years of working to save enough to maintain your current spending. Start at 20, retire at 71.
- 20% Savings Rate: It takes about 37 years. Start at 20, retire at 57. Not bad.
- 50% Savings Rate: It takes about 17 years. Start at 20, retire at 37. Now we’re talking.
Why does the math work this way? Because saving more does two magical things at once.
The Double Whammy of Saving
Increasing your savings rate is the most powerful lever you can pull because it attacks the problem from both sides.
1. You Build Wealth Faster
This is the obvious part. If you save $1,000 a month instead of $100, your pile of money grows ten times faster. Simple.
2. You Need Less Wealth to Survive
This is the hidden superpower.
If you learn to live on 50% of your income, you have proven that you don't need the other 50% to be happy.
This means your "annual expenses" are lower.
And since your retirement number is just a multiple of your annual expenses (usually 25 times), your target number drops.
- Harry spends $245,000. He needs $6.1 million to retire (25 x $245k). That is a huge mountain to climb.
- Tina spends $25,000. She needs $625,000 to retire (25 x $25k). That is a very achievable hill.
Using the Simulator to Find Your Date
You can see this play out in real-time on our Retirement Savings Simulator.
Go ahead and plug in your numbers.
- Plug in your numbers: Fill out the "Salary" and "Current Annual Expenditures" boxes.
- The Experiment: Now, go to the "Current Annual Expenditures" box. Lower it by $5,000. Also lower your "Withdrawals in Retirement" by the same amount
- The Result: Watch two things happen. First, your "Projected Savings" goes up because you are saving that extra $5,000. Second, your "Success Rate" jumps because the simulator accounts for you spending less in retirement, too.
You might find that cutting your spending by just 10% brings your retirement date forward by 5 or 10 years. Is that new car worth 5 years of your life sitting in a cubicle? Only you can answer that.
Strategies to Boost Your Savings Rate
"Okay," you say. "I get it. But I can't save 50% of my income! I have bills!"
I hear you. But most people focus on the wrong bills. They try to save money by skipping the $5 latte (which I’m all for), but they ignore the elephant in the room.
If you want to move the needle, you have to attack the Big Three:
1. Housing
This is usually the biggest expense. Do you need the extra bedroom? Do you need to live in the trendiest neighborhood?
- The Move: Downsizing or "house-hacking" (renting out a room) can cut your biggest bill in half.
2. Transportation
New cars are wealth destroyers. They lose value the second you drive them off the lot, and you pay interest on the loan.
- The Move: Drive a reliable used car. Drive it until the wheels fall off. If your family has two cars, can you get by with one?
3. Food
I love a good steak dinner. But eating out 4 times a week is a budget killer.
- The Move: Learn to cook. It’s healthier, it’s cheaper, and frankly, it’s a great skill to have.
Takeaway: Freedom is Bought
Freedom isn't free. It’s bought.
But it’s not bought with the money you spend. It’s bought with the money you keep.
Every dollar you save is a little soldier fighting for your freedom. Every dollar you spend is a soldier you sent away to fight for someone else (usually a car dealership or a landlord).
You don't have to live like a monk. You don't have to save 50% tomorrow. But start by saving 1% more than you did last month. Then 2%. Then 5%.
Once you see how much closer it brings your finish line, you might just get addicted to saving. And that is a very good addiction to have.
