The Ledger 3 of 6
Cash you can reach, debt that costs more than markets tend to return, and cover for shocks.
2 sourced figuresnext checked 1 March 20271 piece
Before anyone talks about funds or platforms, there is a boring layer: money for a broken boiler, clearing borrowing that charges double-digit rates, and insurance for the events that would otherwise stop everything else. That layer gets skipped because it is dull. It is also where many long-term plans come unstuck.
What this is not
We describe categories and rules. We do not name products or rank providers.
What this subject contains
Convention, not a rule
Most personal finance writing assumes a buffer of essential spending in cash you can reach without selling investments or paying penalties. No statute sets the number of months; it is a widely used rule of thumb, included here because it shapes how people talk about order of operations.
Convention, not a rule
When debt costs more than you assume investments will return, paying the debt off earns the interest rate with certainty. Most guides put that ahead of investing; it is dull, which is partly why it gets skipped.
A band of savings interest taxed at nothing, which shrinks as income rises and vanishes altogether at the additional rate. Rates on cash have been high enough recently that ordinary balances now generate taxable interest for the first time in years.
A further band of savings interest taxed at nothing, available only where other income is low. It is reduced pound for pound by non-savings income, which is why it matters most to people with a small salary and larger savings, including many company directors.
Convention, not a rule
Insurance against long-term illness, death, or losing an earner. Any map of building wealth has to leave room for protection, because illness and bereavement interrupt plans more often than a poor fund choice.
These are the ones that belong to this subject. The whole map, across all six, is on every key way to build wealth.
