Your real financial health in 3 metrics.
People track dozens of financial metrics.
Only three actually determine your trajectory.
The Situation
Most financial dashboards show account balances, credit scores, investment values, and spending categories. But buried inside all that data are three numbers that determine whether you are building wealth or treading water — regardless of income.
Your income shows what you earn. These three numbers show what you're doing with it.

The 3 Numbers · Number 1
Monthly surplus = take-home income minus every real dollar spent, including irregular and annual costs amortized monthly. If this number is negative, everything else is secondary.
Calculate it nowA surplus of even $100/month, invested consistently, is more powerful than a $1,000 windfall spent reactively. Direction matters more than size.
Track the trendThe 3 Numbers · Number 2
This is the single most powerful predictor of retirement timeline. A 10% savings rate means retirement in ~40 years. A 30% rate compresses that to ~20.
Calculate yoursBelow 15%, you are accumulating less than most long-term financial goals require. This is the threshold to protect above all discretionary spending.
Know your floorThe 3 Numbers · Number 3
Below 28%: healthy. 28–36%: manageable. Above 36%: financial pressure. Above 43%: most lenders won't approve new credit — and for good reason.
Know your DTIHigh DTI doesn't just affect borrowing — it reduces your ability to save, invest, and take career risks. It is a ceiling on your financial flexibility.
Reduce it systematicallyAfter the Work
Once you know all three, your financial picture becomes clear:
Surplus positive, savings ≥15%, DTI <28%. You are building.
You have clear, specific levers. Focus sequentially, not simultaneously.
One at a time. Surplus first, then savings rate, then DTI.
You can only improve what you measure. Start measuring.
