"My finances are fine" isn't an assessment — it's reassurance. To know your real financial state, you need measurable numbers.
This is what financial planners use. Calculate them yourself, compare to benchmarks, find the gaps.
1. Savings Rate
Formula: (Monthly savings / Net monthly income) × 100%
Benchmarks:
- < 5% — critical, you can't accumulate
- 5-10% — minimum acceptable
- 10-20% — good
- 20-30% — excellent
- 30%+ — early FIRE trajectory
What counts as savings: money moved into your emergency fund, investments, debt payoff above minimum, contributions to goals. Doesn't count: money just sitting in checking until end of month — that usually gets spent.
2. Debt-to-Income Ratio
Formula: Sum of monthly debt payments / Net income × 100%
Benchmarks:
- < 15% — excellent
- 15-30% — acceptable
- 30-40% — high risk
- > 40% — crisis territory
Count all required payments: mortgage, auto, personal loans, credit card minimums. This is what you must pay even if you lose your job.
3. Emergency Fund Months
Formula: Emergency fund balance / Monthly essential expenses
Benchmarks:
- < 1 month — crisis-ready zero
- 1-3 months — beginner
- 3-6 months — healthy
- 6-12 months — strong (especially for variable income)
Use essential expenses, not total. Not income.
4. Burn Rate
Formula: Average monthly expenses over the last 6 months
Why it matters: shows what you actually cost per month. Most people underestimate by 20-30%.
Benchmark: should stay flat or trend down as income grows. If it scales linearly with income — you're suffering lifestyle inflation, the classic trap. Made more → spent more on restaurants, travel, gadgets. Savings rate didn't budge.
5. Net Worth
Formula: All assets (cash, investments, real estate at market value, vehicles at honest resale) minus all debts
Benchmark: should grow each quarter. By age:
- 25 → ~1× annual income
- 35 → ~3× annual income
- 45 → ~6× annual income
- 55 → ~10× annual income
Aspirational, but show direction. If you're 35 with 0.5× annual income — strategy needs adjustment.
Important: net worth is the difference, not "how much I have." A $400k house with $320k mortgage gives you $80k of net worth on that line, not $400k.
6. Housing Ratio
Formula: (Rent/mortgage + utilities) / Net income × 100%
Benchmarks:
- < 25% — excellent, room for everything else
- 25-35% — normal
- 35-50% — tight
- > 50% — crisis, need cheaper housing or more income
Above 50%, no amount of "financial literacy" can help — the arithmetic doesn't add up.
7. Liquidity Ratio
Formula: Cash + cash-equivalents accessible in 1-3 days / Total net worth × 100%
Benchmarks:
- 100% (all in cash) — under-investing, losing to inflation
- 50-100% — too cash-heavy
- 20-50% — healthy balance
- 10-20% — optimal if your emergency fund is solid
- < 10% — too risky, hard to react to surprises
Composite: Health Score
Apps (including WealthMentor) combine 5-7 metrics into a single 0-100 score.
Rough interpretation:
- 0-40 — critical
- 40-60 — unstable, needs urgent change
- 60-75 — healthy
- 75-90 — excellent
- 90-100 — model, FIRE-trajectory
It's a weighted average of the metrics above, adjusted for age and income.
How to use these
Monthly
- Savings rate
- Burn rate
- Debt/income
Quarterly
- Net worth
- Housing ratio
- Liquidity
Annually
- Goal recalibration based on trajectory
Common blind spots
- Ignoring seasonality. December is usually worst (gifts, holidays). January looks deceptively great (less work, less spending). Use 3-6 month rolling averages.
- Not counting "irregular" income. Bonuses, sales, cashback — they should be in the bigger picture, not "happened, spent."
- Counting gross, not net. $10,000/month gross is not your income — count after taxes.
- Static asset valuations. Real estate prices change. Update yearly, especially before borrowing against or selling.
What to do with bad numbers
Don't panic. Any metric improves with 3-6 months of focused work:
- Low savings rate → audit budget, find 5-10% leakage (subscriptions, impulse spending)
- High debt/income → snowball or avalanche strategy
- Small emergency fund → auto-transfer 10% of every inflow
- Low liquidity → rebalance investments
- High housing ratio → if possible, move / get a roommate / buy vs rent
Bottom line
Financial health isn't "how much money do I have." It's a set of indicators that together describe your resilience. Weakness in one area can be balanced by strength in another, but critical gaps (debt/income > 40%, housing > 50%) need immediate attention.
