What a buffer is
A buffer is a planned margin in your budget that absorbs surprises and rate changes. Without a buffer, normal life turns into debt.
Simple ranges
- 5–10% starter buffer
- 10–15% if your costs fluctuate
- Aim for an emergency fund over time
Bottom line
Buffers buy stability. Treat them as a core budget category.
Quick recap
- Compare scenarios side-by-side using tools.
- Build buffers to survive rate and cost shocks.
- Confirm exact numbers and rules with official sources.
