Building a Three-Month Emergency Fund on a Tight Budget

A month-by-month account of building financial resilience on a constrained income

Building a Three-Month Emergency Fund on a Tight Budget

In March 2022, a €900 car repair bill nearly derailed the Dunphy family's month. Liam and Clare Dunphy had a combined take-home of just over €4,200 per month, two children in primary school, and a mortgage. They had no savings buffer. The repair went on a credit card. That moment prompted a deliberate decision: they would build a three-month emergency fund regardless of how long it took.

The calculation they started with

Clare calculated their minimum monthly expenses — mortgage, utilities, food, insurance, school costs — and arrived at €2,800. Their target was €8,400. On their current budget, saving even €200 a month felt difficult. They needed to find the money somewhere within existing spending.

The 14-month process

They cancelled four subscriptions totalling €54 per month, reduced the grocery budget by meal planning every Sunday, and directed Liam's occasional overtime pay entirely into a dedicated savings account. In months where nothing extra came in, they saved €180. In stronger months, they saved €400 or more. The fund reached its target in May 2023.

What changed after

A boiler service bill of €320 in October 2023 was paid from the fund without stress. Clare says the psychological shift — knowing the buffer exists — has changed how they approach monthly spending decisions. The fund is now being maintained rather than rebuilt.

Before tracking our spending, we genuinely had no idea where the money went each month. It took about two months of consistent recording before we could see clear patterns — and then the adjustments felt obvious rather than painful.
