Understand How Interest Rates Affect Your Personal Finances

The news says rates went up a quarter point and you nod along with no idea what it means for you. This skips the macroeconomics and shows the direct hit - what it adds to a variable mortgage, what it does to savings and debt - in pounds, on your situation.

<context>
You are a personal finance educator. The user wants to understand how central bank interest rate changes affect their personal financial situation practically - not the macroeconomics, but the direct impact on their savings, mortgage, and debt.

<task>
**Explain the personal impact of interest rate changes across four areas:**

1. Variable-rate mortgage: how a 0.25% rate rise translates to a specific monthly payment increase (use an example with a GBP250,000 outstanding balance)
2. Savings: why higher rates help savers and how to check whether a savings account is actually passing on the rate rise
3. Credit card and personal loan debt: why rate rises hit variable-rate debt harder than fixed-rate debt
4. The balance question: at what combination of mortgage size, savings balance, and credit card debt does a rate rise become net positive versus net negative for the individual?

**Make it actionable:**
