Guides
- How much emergency fund do I need?
The three-to-six-months rule explained properly: what counts as essential spending, when three months is enough, and where to keep the money.
- Is paying more into my pension worth it?
What an extra 1% really costs your take-home after tax relief, why the employer match beats everything else, and when to hold off.
- How much should I save each month?
The 20% rule explained, the priority order that beats it, paying yourself first, and what to do when 20% is out of reach.
- Cash ISA vs savings account: which pays more?
When a cash ISA beats an ordinary savings account: the personal savings allowance, the £20,000 limit, and why the rate matters most.
- How compound interest actually works
Growth on growth, why starting early beats paying in more, the rule of 72, and worked 10, 20 and 30 year examples in pounds.
- Do I pay tax on savings interest?
The personal savings allowance by tax band, why frozen thresholds drag more savers in, and when an ISA beats a higher headline rate.
- How much pension do I need to retire at 60?
Realistic pot sizes for retiring at 60, the seven-year gap before the state pension, and how to test your own number.
- Can I take 25% of my pension tax-free at 55?
Yes, within limits. The lump sum cap, the age rising to 57 in 2028, and the emergency-tax trap on first withdrawals.
- What happens to my pension when I die?
Who gets your pot, how age 75 changes the tax, and the expression-of-wish form most people never complete.
- ISA or pension: which is better?
Pension wins on tax relief and the employer match, ISA wins on access. The order of operations that uses both properly.
- Should I consolidate my pensions into one pot?
Usually yes for old high-fee DC pots, almost never for defined benefit. The fee-drag maths and a lost-pot tracing checklist.
- How much state pension will I get with 20 years of NI?
The 35ths formula made concrete: what 10 to 35 qualifying years each pay, and when buying missing years is worth it.
- Are premium bonds worth it?
What median luck actually returns at each holding size, and who genuinely beats a savings account by holding them.
- Can I retire at 60 with £500k?
Roughly £20k to £25k a year sustainably, more once the state pension arrives. The drawdown maths behind the answer.
