Your savings rate is the single most important number in personal finance. It determines how fast you build wealth, regardless of how much you earn.
Your savings rate is the percentage of your income that you keep after all expenses. It's the gap between what you earn and what you spend, expressed as a percentage.
If you earn €4,000 per month and spend €3,000, you save €1,000. Your savings rate is 25%.
This number matters because it directly controls how fast you accumulate wealth. A high income means nothing if you spend it all. A modest income with a strong savings rate builds real financial security over time.
In Boring Money, your savings rate is front and center on the dashboard because we believe it's the metric that actually drives financial health, not your account balance, not your salary.
Use the income you actually receive and track. In Boring Money, you enter your income as it comes in (salary, freelance, side income), and the app calculates your savings rate from there. No need to worry about gross vs. net distinctions, just enter what you actually get.
Some people in the FIRE community also include employer retirement contributions (like a 401(k) match) in both income and savings. That's valid, but keep it consistent month to month. What matters most is tracking the trend, not the exact methodology.
Most people focus on earning more. But your savings rate matters far more for building wealth. Here's why:
Sofia earns less than half of Alex but saves 3x more each month. After 10 years of investing at 7% returns, Sofia has ~€207,000 while Alex has ~€69,000.
Your savings rate directly controls how many years until you can live off your investments. At 10%, it takes ~40 years. At 50%, ~15 years. At 75%, ~7 years. The math is the same regardless of income level.
You can't always control your income (raises depend on employers, markets, timing). But you can always control your spending. Your savings rate reflects the choices you make every day.
A higher savings rate does double duty: it increases the money you invest and it lowers the expenses your investments need to cover. Someone who needs €2,000/month to live requires half the portfolio of someone who needs €4,000/month.
A high savings rate means you're living well below your means. If your income drops, you have a large buffer before you're in trouble. It also means your emergency fund fills up faster.
There's no single "right" savings rate. It depends on your income, cost of living, goals, and life stage. Here's a general framework:
Living paycheck to paycheck. One unexpected expense can create debt. Priority: build an emergency fund and look for expenses to cut.
You're saving, but slowly. At 15%, traditional retirement is achievable. Good foundation to build on.
The sweet spot for most people. You're building wealth consistently, can handle emergencies, and are on track for a comfortable retirement. The 20% target is a classic recommendation.
Wealth is growing fast. Financial independence becomes possible in 15-20 years. You have significant flexibility if your income changes.
Financial independence in 10-15 years. Requires either a high income, very low cost of living, or both. Not sustainable for everyone, but transformative for those who can.
Assuming 7% annual returns and expenses stay constant. Based on the 4% rule.
There are only two levers: earn more or spend less. Most people have more room on the spending side than they think. Here's a practical approach:
You can't improve what you don't measure. Track all your expenses for a full month before making changes. Most people are surprised by how much they spend on things they don't value.
Housing, transportation, and food typically account for 60-70% of expenses. A small percentage reduction on these has more impact than eliminating small luxuries. Can you move closer to work? Switch to public transit? Meal prep more?
List every subscription and recurring payment. Cancel anything you don't actively use. Negotiate better rates on insurance, phone, and internet. These savings compound every month.
On payday, immediately transfer your target savings amount to a separate account. Then live on what's left. This flips the script: instead of saving what remains after spending, you spend what remains after saving.
When you get a raise, keep your lifestyle the same and direct the extra income to savings. This is the easiest way to boost your savings rate because you never "had" the money, so you don't miss it. This directly fights lifestyle inflation.
Give yourself a budget for entertainment, dining out, and shopping. You don't have to cut these to zero. Intentional spending on things you value is fine. The goal is to eliminate mindless spending on things you don't.
Knowing the theory is great. But tracking your savings rate manually in a spreadsheet gets old fast. Boring Money automates the entire process:
Stop guessing your savings rate. Track it automatically and watch it improve.
Start tracking your savings rateA bad month doesn't ruin your finances. What matters is the trend over 3, 6, 12 months. December will always be lower. January might spike. Look at the moving average, not individual data points.
Getting a 20% raise and immediately upgrading your apartment, car, and subscriptions. Your income went up but your savings rate stayed the same (or dropped). Each raise is an opportunity to widen the gap, not match it with new expenses.
Going from 10% to 60% overnight is like a crash diet: you'll burn out and rebound. Aim for gradual improvements. Increase your savings rate by 2-5% every few months. Sustainable beats dramatic.
Cutting expenses has a floor (you still need to eat and have shelter). Income has no ceiling. Negotiating a raise, developing a side skill, or switching jobs can boost your savings rate more than any frugality hack.
"I think I save about 20%." You probably don't. People consistently overestimate their savings rate. The only way to know is to track every expense. That's why active tracking beats passive bank syncs: it creates real awareness.
Yes, money invested is money saved. In Boring Money, when you transfer money to your broker and buy ETFs or stocks, that money isn't counted as an expense. It moved from liquid assets to investments but it's still yours. Goal contributions, however, are treated as expenses since they're earmarked for future spending.
A negative savings rate means you're spending more than you earn, either drawing down savings or accumulating debt. This is a red flag that needs immediate attention. Start by tracking all expenses to find where the money goes, then focus on the biggest categories.
Absolutely. Debt payments reduce your expenses faster, which improves future savings rate. Build a small emergency fund first, then aggressively pay off high-interest debt. As debt disappears, your savings rate naturally increases because those payments become available for saving.
Track it monthly for awareness, but evaluate it annually for decision-making. Monthly rates fluctuate due to irregular expenses (insurance premiums, car maintenance, holiday gifts). Your annual average smooths these out and gives you the real picture.
For a shared household, add both incomes together and subtract all household expenses. This gives you the household savings rate, which is what matters for shared financial goals. You can also track individual rates if you maintain separate finances for personal spending.
Boring Money puts your savings rate front and center. Track expenses, set budgets, and watch your savings rate improve over time.
