This calculator provides a suggested emergency fund range based on general financial planning principles and the factors you have provided. It is for informational purposes only and does not constitute financial advice. The recommended amount is illustrative — your actual needs may differ significantly based on circumstances not captured here, including specific financial commitments, health considerations, and employment terms. Opportunity cost figures assume a 7% average annual investment return which is not guaranteed. Selvox accepts no liability for decisions made in reliance on these outputs.
