and when each triggers action.

You do not need to obsess over your finances. You need a system that surfaces problems early. These nine metrics, tracked on the right schedule, do that. Each one comes with a specific trigger that tells you when something needs attention.

This page covers US-specific accounts and tax law. Outside the US? The priority order is the same, the account names differ (ISA in the UK, TFSA/RRSP in Canada, Super in Australia, etc.).
THE SHORT VERSION

Track net worth monthly. Savings rate monthly. Expense breakdown monthly. Credit score quarterly. Asset allocation quarterly with rebalance trigger at 5% drift. Insurance coverage annually. FIRE number annually. Emergency-fund ratio when expenses change. Debt progress monthly while debt exists. Everything else follows from these.

Metric 1: Net worth

Track: Monthly. Formula: Total assets minus total liabilities.

Assets: bank accounts, investments, retirement accounts, Bitcoin, home equity, other property. Liabilities: mortgage, car loans, student loans, credit card balances, other debt.

Trends matter more than snapshots. One month tells you little. Twelve months tells you whether you are building or treading water.

Triggers:

Net worth declined two months in a row: review expense breakdown and find the leak. Flat for 6+ months despite positive income: savings-rate problem, expense audit required.

Metric 2: Savings rate

Track: Monthly. Formula: (Income minus spending) / income, times 100. Or: total invested this month / total income this month, times 100.

Include all savings: 401(k) (employee portion only), Roth IRA, HSA, taxable investments, cash saved and not yet invested.

Targets by life stage: building foundation (20s): 10 to 20%. More capacity (30s): 20 to 30%. FIRE pursuer: 40 to 70%. See the full table in Financial Numbers.

Trigger:

Savings rate under 10% for more than two months: find the spending category that grew and address it.

Metric 3: Expense breakdown

Track: Monthly. Categories at minimum: housing (rent/mortgage/insurance/tax), transportation, food (groceries + dining separate), healthcare, debt payments, subscriptions, discretionary.

Target maximums as % of take-home: housing under 30%, transportation under 15%, food under 12%, healthcare under 8%, debt under 20% (zero is the target for consumer debt).

Trigger:

Any category over target for two consecutive months: investigate and address before it compounds.

Metric 4: FIRE number and years to FI

Track: Annually, or when major expenses or income change. Formula: annual expenses × 25 (standard 4% SWR) or × 28 to 33 for early retirement.

Triggers:

FIRE number grew significantly year over year: lifestyle-inflation check, is the increase intentional? Years to FI extended: savings rate dropped or returns were poor; the controllable part is the savings rate.

Metric 5: Asset allocation vs target

Track: Quarterly. Rebalance trigger: any asset class drifts more than 5% from target.

Example target: 80% US total market (VTI/FSKAX), 15% international (VXUS), 5% Bitcoin. Each person's target differs; this is just illustrative.

Rebalance by adding new contributions to underweight categories first (tax-efficient, no selling needed). Sell overweight only if contributions cannot fix it, and even then prefer selling inside tax-advantaged accounts.

Trigger:

Any asset class over 5% drift: rebalance at next contribution. Bitcoin over 40% of portfolio: review Bitcoin Allocation for position sizing.

Metric 6: Credit score

Track: Quarterly. Free sources: Credit Karma (TransUnion + Equifax), Discover Credit Scorecard (FICO, free to anyone), many credit cards now show free FICO in-app.

Your credit is frozen per Credit Freeze. A freeze does not affect your score. The score continues to update.

Benchmarks: under 670 needs work, 670 to 739 good, 740 to 799 very good, 800+ exceptional ×DON'T TRUST, VERIFYClaim: FICO score bands: Poor <580, Fair 580-669, Good 670-739, Very Good 740-799, Exceptional 800+.Verify at: myFICO score ranges ↗Standard FICO 8 bands. VantageScore uses similar but not identical bands..

Triggers:

Score dropped 20+ points: check all three credit reports for errors or fraud at AnnualCreditReport.com. Under 740 and planning a mortgage soon: optimize (pay down balances, do not close old cards).

Metric 7: Insurance coverage vs net worth

Track: Annually. Review life insurance vs dependents' actual needs, disability coverage vs actual income, umbrella coverage vs total net worth, auto liability limits vs net worth (minimum 100/300/100 for most).

Trigger rule:

If net worth exceeds your auto liability coverage, increase coverage or add an umbrella policy. $1M umbrella runs approximately $150 to $300 per year for most people.

Metric 8: Emergency fund ratio

Track: When expenses change significantly (new rent, new child, new mortgage). Formula: emergency fund balance / monthly fixed costs.

Targets: minimum 3 months, recommended 6 months, 9 to 12 months if self-employed or variable income.

Trigger:

Ratio falls below 3 months: pause non-essential investing. Rebuild the emergency fund first. Then resume.

Metric 9: Debt payoff progress

Track: Monthly while debt exists. Once debt-free, retire from tracking. Track total balance on each debt, interest rate, minimum payment, and extra payment applied this month.

Trigger:

New debt over 7% APR appears: reprioritize to pay it off before investing beyond employer match.
