- Category card (5% on rotating spending)

- Space applications by 6 months (UK/US) or 3 months (AU/CA)
- Hard inquiries stay on report:
- USA: 2 years

- UK/AU: 12 months
4. The Interest Avalanche
- Always pay statement balance in full
- If carrying debt:

5. The Annual Fee Test
Calculate: (Yearly Rewards Value) - (Annual Fee) = Net Benefit Good: £100 fee with £300+ value
Bad: £450 fee with £200 value
