Choose the life event first, then follow the calculators, explainers and checks in the right order. This is for the moments where one number is not enough: pay rises, childcare, buying a home, HMRC letters, investing, self-employment and retirement.
Most money mistakes happen when the tool is chosen before the question is clear. Filter by topic, select the closest life event, then use the report panel as your route through the site.

Tax traps route
I think I hit a hidden tax trap
Use this when the result looks worse than the headline tax rate: pay rise, bonus, 60% zone, Child Benefit, childcare, emergency tax, savings, dividends, CGT or pension allowance.
Find the threshold first.
Check adjusted net income where relevant.
Open the calculator only after the trap is identified.

Everyday money route
I need to get normal money under control
Use this when credit cards, bills, loans, overdrafts or switching admin matter more than another tax wrapper comparison.
Separate bills, spending, buffers and goals.
Rank debt by cost and risk before adding new products.
Use switching bonuses only after payment timing is safe.
Life events route
Something in my life changed
Use this when the real problem is a life event: first job, renting, baby, redundancy, illness, caring, separation, bereavement, retirement or self-employment.
Start with the moment, then choose the tool.
Protect bills, benefits and deadlines before optimisation.
Use official links where rules can change.
Income route
I got a pay rise or bonus
Use this when your salary changed and you want to know what you actually keep after tax, NI, student loans and threshold effects.
Compare old pay, new pay and bonus cash kept.
Check adjusted net income before childcare or Child Benefit decisions.
Use salary sacrifice as a scenario, not as a reflex.
Family route
I had a baby or childcare changed
Use this when your household has children, leave, childcare bills or one parent near a benefit threshold.
Check Child Benefit charge before making pension choices.
Price leave periods week by week.
Compare childcare support routes before changing payroll elections.
Property route
I am buying a home
Use this when the question is not only affordability, but whether the purchase makes sense after costs and timing.
Run rent versus buy before falling in love with a property.
Price the mortgage at different rates and terms.
Add transaction taxes and process steps early.
HMRC route
I got an HMRC letter or tax code
Use this when you need to work out what HMRC is actually asking for before calculating anything.
Identify the letter or tax-code type.
Check whether a refund, underpayment or filing duty is likely.
Use the calendar if a deadline is involved.

Investing route
I want to invest properly

Decide ISA, pension or GIA tax wrapper before product selection.
Use ETF checks for role, cost, risk and overlap.

Business route
I am self-employed or contracting

Check filing duty before structure.
Model profit and tax under the realistic route first.
Add VAT, IR35 and director extraction only when relevant.
Use this when you need the retirement income picture, not just a pension balance.

Check workplace pension, old pots and State Pension gaps.
Compare ISA and pension flexibility before drawdown.
Life events command centre
When life changes, choose the checklist first
These are the pages for moments where the financial question is bigger than one calculator. Start with the event, then open the workbook, benefit route, tax tool or debt help page that fits.
Use before large pension contributions, salary sacrifice, taper checks or drawdown decisions.
Tax-year command centre
The dates and resets that quietly change the answer
Some decisions should be reviewed when allowances reset, thresholds bite or Self Assessment deadlines approach. Use these pages when the timing is part of the decision.
One calendar for the deadlines that can change what you should do next.
Household dashboard
Build a full household picture in four passes
Premium planning is rarely about one perfect tool. It is about doing the passes in the right order, then saving scenarios while the numbers are still fresh.
Use the knowledge route before the calculator route
If a term, letter or threshold is confusing, pause before entering numbers. The professional habit is to understand the rule, inspect the assumptions, then run scenarios.
