How to Increase Your Savings Rate

Previously, you calculated your savings rate. Maybe the number surprised you. Maybe it motivated you.

But a natural question comes next:

👉 How do you increase it… without turning your life into a permanent diet?

Because let's be clear: FIRE isn't a deprivation contest. It's an optimization game.

The Trap to Avoid: Believing Everything Comes Down to Restriction

When people talk about saving, many immediately picture:

  • cutting out restaurants

  • skipping vacations

  • living at the "bare minimum"

👉 Wrong approach.

Why? Because it doesn't last.

The real strategy is to maximize the value of every euro spent, not to cut everything across the board.

The 3 Levers That Actually Make a Difference

1. Big expenses (massive impact)

This is where it all happens.

The three biggest categories in almost every budget:

  • housing

  • transportation

  • food

👉 Reducing each of these by 10–20% has a huge impact.

Concrete examples:

  • a slightly smaller home, or one negotiated better

  • a simpler car (or one you replace less often)

  • optimized grocery shopping without sacrificing quality

💡 A single smart decision here can be worth years of small, pointless savings elsewhere.

2. Automation (invisible effect)

What works best is what doesn't depend on your willpower.

👉 Set up a system:

  • automatic investing every month

  • transfer as soon as income arrives

  • savings "deducted" before you spend

Result: You naturally adapt to what's left. No mental effort required.

3. Aligning with your real priorities (anti-frustration effect)

Not all expenses are equal.

👉 Ask yourself a simple question: "Does this expense actually improve my life?"

You'll discover two categories:

  • high-value expenses (travel, family time, health…)

  • "default" expenses (subscriptions, impulse buys, social habits)

The FIRE strategy isn't to cut everything.

👉 It's to spend more on what truly matters… and less on the rest.

An Important Truth: You Don't Need to Be Perfect

Many people give up for the wrong reason:

👉 They want to optimize 100%.

In reality:

  • going from 20% to 30% already changes your trajectory enormously

  • going from 30% to 40% is even more powerful

But every +5% is already a win.

Classic Mistakes to Avoid

  • Optimizing only small pleasures (coffee, outings…)

  • Ignoring the big decisions (housing, car)

  • Trying to move too fast → frustration → giving up

  • Not investing (savings sitting idle = invisible loss due to inflation)

👉 Remember: consistency beats perfection.

A Concrete Example

Let's revisit a simple case:

  • Income: €6,000

  • Expenses: €3,500

  • Savings: €2,500 → 41.6%

If you reduce your expenses by just €500:

  • new expenses: €3,000

  • savings: €3,000

  • savings rate: 50%

👉 Result: a massive acceleration… without radically changing your life.
