Smart saving

Building an emergency fund without falling asleep

Mix high-yield accounts, Spanish T-bills and a monthly habit to hit six months of expenses by 2026.

Key takeaways

Splitting the goal into micro-milestones and indexing it to inflation keeps the fund relevant.

  • Keep the first two months ultra-liquid and search moderate yield for the remainder.
  • Automate the monthly transfer the day after payday.
  • Revisit the fund quarterly and adjust for CPI.

Divide and conquer

Use the savings calculator to total fixed plus variable costs and set a 3, 4 or 6 month target. Park the first block in a no-penalty high-yield account.

Allocate the second block to 6–9 month Spanish T-bills. Short ladders let you capture higher yields without sacrificing liquidity.

Quick tips

  • Nickname each sub-account to build friction before dipping into it.
  • When you get a bonus, route at least 30% into the fund before investing.

Quarterly review

Index the goal using Spain’s core inflation. If expenses rise 2%, tweak the monthly transfer accordingly.

Use that check-in to sweep any excess into your investment plan—automation prevents both underfunding and drag.
