Your savings rate โ the percentage of your income you save each month โ is arguably the single most important number in personal finance. It determines how fast you build wealth, when you can retire, and how resilient you are to financial shocks. But what counts as a "good" savings rate?
Financial advisors typically recommend saving at least 20% of your net income. The widely-known 50/30/20 rule suggests allocating 50% to needs, 30% to wants, and 20% to savings and debt repayment. But this is a starting point, not a destination.
UK average: The US household savings ratio was around 10โ11% in 2024. If you're hitting 20%, you're ahead of most people. If you're hitting 30%+, you're on track to significantly accelerate your financial independence.
The formula is simple:
Savings Rate = (Money Saved รท Gross Income) ร 100
For example: if you earn $3,500/month after tax and save $700, your savings rate is 20%. Some people calculate this on gross income; others use net (take-home) pay. What matters is consistency โ pick one and stick with it.
Include all forms of saving: pension contributions (including employer match), ISA contributions, emergency fund top-ups, and debt overpayments count.
Our Savings Rate Calculator shows your current rate and charts exactly how long it will take you to reach financial independence at your current pace.
Use the Savings Rate Calculator โThe FIRE (Financial Independence, Retire Early) movement is built almost entirely on the savings rate. The underlying maths, popularised by Mr Money Mustache, shows that at a 50% savings rate, you need roughly 17 years of work to retire. At 25%, it's closer to 32 years. At 10%, you're looking at 45 years.
This assumes your investments grow at roughly 5โ7% after inflation, and that you can live on 4% of your portfolio annually (the "4% rule").
The FIRE Calculator tells you exactly when you can retire based on your current savings rate, existing portfolio, and expected returns.

A good savings rate is one you can sustain. Starting at 10% and increasing it by 1โ2% each year as your income grows is a more reliable path than attempting an aggressive rate that collapses after a month. The most important thing is to start now โ time in the market compounds far more powerfully than the savings rate itself.
