Building an emergency fund starts with deciding on a target: 3 months of essential expenses is minimum, 6 months is better for people with variable income or dependants.
Calculate your monthly essentials: rent, food, utilities, transport, minimum debt payments. Not luxuries, just what you'd need to survive a job loss. If that's £1,500, your target is £4,500-£9,000.
Open a separate high-yield savings account specifically for this fund — keeping it separate makes it psychologically easier to leave alone. In the UK Marcus by Goldman Sachs and Chase's savings account offer competitive rates. In the US, Ally Bank and Marcus are popular.
Start small. Even £50/month builds the habit. Automate it so the transfer happens on payday. Treat it as non-negotiable. Use any windfalls — tax refunds, bonuses, birthday money — to accelerate it.
Once fully funded, you invest with much more confidence knowing you have a cushion.
