Stability first
Make sure a bad month does not force expensive debt or a rushed investment sale. Start with the Emergency Fund Calculator.

Sources shown where tax rules matter
Start here: the order matters
Most financial plans are built in layers. Each layer need not be perfect from day one, but getting the order right from the start gives everything that follows a better chance of working.
Do not ignore employer money
If your employer adds pension contributions when you do, that can beat almost any clever investing idea. Check it before you optimise the rest.
Invest for the goals with time
Longer timeframes give investments more room to work. Use the Investment Calculator to test the difference between starting small and waiting.
Choose the wrapper deliberately
An ISA, pension and taxable account can hold similar investments but produce different outcomes. Sometimes the wrapper matters as much as the fund. The ISA vs Pension Calculator lets you test that trade-off with your own numbers.
Know how you will take it out
Building a pot is one half of the plan. The other is knowing how long it needs to last and what you can safely withdraw. Use the Drawdown Calculator to test your numbers before you rely on them.
The questions behind the calculators
These are the questions each calculator is built to help you think through.
How much should I invest each month?
There is no universal answer. The calculator helps you find a number that fits your income, your timeline and what you are working towards.
How much emergency fund do I need?
It depends on your situation. The calculator works it out based on your spending, your income and who relies on you.
Should I use an ISA or pension?
Compare access, tax relief, salary sacrifice and pension access age with the new calculator.
Is salary sacrifice worth it?
Check how much pension contribution you get for the take-home pay you give up.
Should I overpay my mortgage or invest?
Compare mortgage interest saved with the uncertain return from investing.
How long will my pension pot last?
Test withdrawals, returns and pot size before relying on a drawdown plan.
Where money goes when you invest it
Each asset type has a different job. A cash savings account and a global index fund are not competing; they serve different purposes at different stages.
Cash and savings
Useful for emergency funds and short-term goals. Cash is stable and accessible, but may lose buying power after inflation.
- Good for money needed soon
- Check FSCS protection and access terms
Stocks and shares
Shares give exposure to companies. They can produce long-term growth, but values can fall sharply along the way.
- Higher volatility than cash or bonds
- Often held through funds or ETFs
Bonds
Bonds are loans to governments or companies. They can add income and stability, but they still carry interest-rate and credit risk.
- Can reduce portfolio volatility
- Not risk-free
Funds and ETFs
Funds and exchange-traded funds pool investments. A single global fund can hold hundreds or thousands of companies.
- Useful for diversification
- Fees matter over time
- Check what the fund actually owns
- Costs vary widely: from cheap index trackers to expensive active funds
Property
Property can provide income and capital growth, but it is concentrated, expensive to buy and sell, and often illiquid.
- Less liquid than funds
- Costs and tax can be significant
Alternative assets
Crypto, private investments, commodities and specialist strategies can be complex and volatile. They are rarely the first place a beginner should start.
- Higher complexity than mainstream assets
- May be hard to value
Core investing concepts
These ideas make the calculator results easier to interpret.
Compound growth
Growth can earn future growth. Time matters because later returns may apply to a larger pot.
Contributions
For most people, regular contributions drive early progress more than investment return. Return becomes more important as the pot grows.
Annual return
The annual return in a calculator is an assumption, not a forecast. Testing 4%, 6% and 8% can be more useful than pretending one number is certain.
Volatility
Investments move up and down. A plan that only feels acceptable when markets rise is not a plan you will stick with.
Diversification
Spreading money across companies, sectors and countries reduces dependence on one outcome.
Inflation
Inflation reduces buying power. A future pot may look large in pounds but buy less than expected.
Fees
Fees are one of the few things you can control. Small differences can compound over decades.
Sequence risk
The order of returns matters when withdrawing money. Bad early years in retirement can do more damage than bad later years.
Liquidity
Liquidity means access. A pension can be tax-efficient but locked away; cash is accessible but usually grows more slowly.
UK wrappers in plain English
The account you use can change the result. That is why some calculators ask whether money is inside an ISA, pension or taxable account.
ISA
Tax-free savings or investments within the annual ISA allowance. Usually flexible access, depending on the product.
Pension / SIPP
Usually tax-efficient for retirement, especially with employer contributions or salary sacrifice, but access is restricted.
General Investment Account
Flexible, but dividends and capital gains can be taxable above allowances. Useful after ISA/pension allowances or for specific needs.
