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.
- How much do I need to retire comfortably in the UK?
The PLSA retirement living standards for 2026: what minimum, moderate and comfortable cost a year, the pension pot behind each, and how to find your own number.
- Cash ISA vs stocks and shares ISA: which is better?
Cash ISAs are safe and predictable, stocks and shares ISAs grow more over time but fall along the way. How to choose by your time horizon, not by the label.
- Lifetime ISA vs pension: which is better for me?
The LISA gives a 25% bonus up to £1,000 a year; a pension gives bigger tax relief and employer money. When each one wins, and why most people use both.
- Annuity vs drawdown: which is right for you?
Annuities give guaranteed income for life, drawdown keeps your pot invested and flexible. How the two compare in 2026, the risks of each, and why many blend them.
- How many ISAs can I have? (2026/27 rules)
Since April 2024 you can pay into multiple ISAs of the same type in one year. The four types, the single £20,000 allowance, the LISA sub-limit and transfers explained.
- Junior ISAs explained: allowance, rules and how they work
A Junior ISA lets you save up to £9,000 a year tax-free for a child. Cash vs stocks and shares, who can open one, when the child gets the money, and a worked example.
- SIPP vs workplace pension: should you have both?
Workplace pensions give you free employer money you should never refuse; a SIPP gives you investment choice. How to use both, and when to consolidate.
- Pension annual allowance and carry forward explained
The £60,000 annual allowance, how carry forward lets you use up to three unused years, the taper for high earners, and the £10,000 MPAA trap.
- Defined benefit vs defined contribution pensions: what's the difference?
Defined benefit pays a guaranteed income for life; defined contribution builds a pot you invest and bear the risk on. How to tell which you have.
- Regular saver accounts: how they work and are they worth it?
Regular savers advertise big rates like 7%, but interest builds on each monthly deposit, so the real return over the year is roughly half the headline.
- Workplace pensions and auto-enrolment: how do they work?
Employers must auto-enrol eligible staff into a pension: minimum 8% total, with 3% from the employer. Why opting out throws away free money.
