Emergency fund
A cash cushion turns a crisis into an inconvenience — the single biggest reducer of money stress.
Priority Matrix
The numbers.
Four dimensions, scored 1–6, where six is always the good end: cheapest, quickest, easiest, highest impact. Priority is Impact squared, divided by what it costs you in energy, money and time.
How sure we are
Kept separate from the priority score on purpose: confidence in the evidence never raises how worth-it something is.

- How Your Bank Balance Buys Happiness: The Importance of "Cash on Hand" to Life Satisfaction
Emotion · 2016
Among 585 UK bank customers whose balances were verified by the bank, going from £1 to £1,000 of liquid savings was associated with a 2-point gain on a 20-point life-satisfaction scale — entirely via feeling financially secure, and with sharply diminishing returns above that.
- Emergency Saving and Household Hardship
Journal of Family and Economic Issues · 2016
In a longitudinal sample of low-income US households, those who reported saving for emergencies were less likely to experience later hardships such as food and energy insecurity.
- Financial stress and depression in adults: A systematic review
PLOS ONE · 2022
Across 40 observational studies, financial stress was consistently associated with depression — strongest among people with low income or wealth — but heterogeneity prevented a pooled effect size and causation could not be established.
- The relationship between personal unsecured debt and mental and physical health: A systematic review and meta-analysis
Clinical Psychology Review · 2013
Pooling studies covering nearly 34,000 people, those in unsecured debt had roughly three times the odds of a mental health problem — the debt cascade an emergency fund exists to prevent.
- Report on the Economic Well-Being of U.S. Households in 2024 (SHED) — Savings and Investments
Federal Reserve Board · 2025
In 2024, 37% of US adults could not cover a $400 emergency expense with cash or its equivalent, 13% could not pay it by any means, and only 55% had three months of expenses saved.

Where this falls down
All the wellbeing evidence is correlational — no one has run an RCT handing people emergency funds. The life-satisfaction link is modest (r ≈ .21; the first ~£1,000 is worth about 2 points on a 20-point scale) and flattens fast above sufficiency — this is a floor, not a ladder, and piling up cash past a few months of expenses buys little extra.
It also requires income margin: the 13% of US adults who can't cover $400 by any means can't simply choose this card, and they're the group the hardship data says it would help most.
