Your Savings Rate Matters More Than Your Salary

The Most Important Number You're Not Tracking

Your savings rate is the percentage of your income that you save and invest. It's the single most powerful predictor of when you can quit your job — more powerful than your salary, your investment returns, or your age.

Here's why: your savings rate simultaneously does two things. It increases how much you're investing each month AND it proves you can live on less, which lowers your Quit Number.

Savings Rate to Years Until Freedom

Assuming 7% annual investment returns and starting from zero, here's how savings rate maps to years until financial independence:

• 10% savings rate → ~51 years to FI
• 15% savings rate → ~43 years to FI
• 20% savings rate → ~37 years to FI
• 25% savings rate → ~32 years to FI
• 30% savings rate → ~28 years to FI
• 35% savings rate → ~25 years to FI
• 40% savings rate → ~22 years to FI
• 50% savings rate → ~17 years to FI
• 60% savings rate → ~12.5 years to FI
• 70% savings rate → ~8.5 years to FI
• 80% savings rate → ~5.5 years to FI

The relationship is non-linear. Going from 10% to 20% saves you 14 years. Going from 50% to 60% saves you 4.5 years. The biggest gains come from getting out of the low savings rates.

Why Salary Doesn't Matter as Much as You Think

Consider two people:

Alex earns $200,000/year and spends $170,000/year. Savings rate: 15%. Alex saves $30,000/year and needs a Quit Number of $4,250,000 (25 × $170,000). Time to FI: about 43 years.

Jordan earns $75,000/year and spends $37,500/year. Savings rate: 50%. Jordan saves $37,500/year and needs a Quit Number of $937,500 (25 × $37,500). Time to FI: about 17 years.

Jordan earns less than half of what Alex makes but will reach financial independence 26 years sooner. The savings rate changes everything.

How to Increase Your Savings Rate

There are only two sides of this equation: earn more or spend less. Most people can do both.

Quick Wins on the Spending Side

• Housing: This is usually 30-40% of expenses. Moving to a cheaper place, getting a roommate, or refinancing can free up hundreds per month.
• Transportation: A paid-off car instead of a $500/month car payment changes your timeline by years.
• Subscriptions: Audit every recurring charge. Most people have $100-300/month in subscriptions they barely use.
• Food: Cooking at home vs. eating out is a $300-600/month difference for most people.

Bigger Moves on the Income Side

• Negotiate your salary. Most people leave $5,000-15,000 on the table by not negotiating.
• Switch jobs. The average raise from switching employers is 10-20%, compared to 3-5% for staying.
• Start a side income. Even $500/month extra — invested consistently — can shave years off your timeline.
• Develop high-value skills. Investing in skills that increase your earning power compounds over your entire career.

The Biggest Obstacle

Lifestyle inflation. As income rises, spending rises to match. A $20,000 raise that turns into a nicer apartment and a new car payment does nothing for your savings rate. The antidote is simple: every time your income goes up, keep your expenses flat and invest the difference.

Track Your Real Numbers

You can't manage what you don't measure. Calculate your current savings rate and Quit Date right now. Then look at the table above and ask: "What would it take to move up one tier?"

Going from a 20% savings rate to 30% cuts 9 years off your timeline. That's worth a few lifestyle adjustments.
