The Opportunity Cost of Cash
Every €1,000 kept in cash instead of invested at 7% could earn €967 over 10 years. This calculator quantifies that cost for your numbers.
Why 3-6 Months?
Irish financial advisors recommend 3-6 months of essential expenses as an emergency fund. Less than 3 months risks shortfall; more than 6 months starts costing significant investment growth — especially with DIRT at 33% eroding cash returns.
DIRT Eats Cash Returns
Irish deposit interest is taxed at 33% DIRT. A 3% savings rate becomes ~2% after tax — while investments like global ETFs have historically returned 6-9% before taxes.
The Split Strategy
A balanced approach: invest 50% of your surplus immediately while using the other 50% to build your emergency fund. Once funded, redirect all surplus to investments — giving you market exposure with adequate protection.
