Make every personal finance decision with clarity — not anxiety. From budgeting and debt payoff to FIRE planning and net worth tracking, our 10 free tools help you understand where you stand and what to do next.
Personal finance is not complicated — but it is often emotionally charged and rarely taught. Understanding three numbers changes everything: your savings rate (what percentage of income you keep), your net worth trajectory (are assets growing faster than liabilities?) and your financial independence number (how much you need to never work again). Our calculators make all three visible.
A simple framework: 50% of after-tax income on needs (housing, food, utilities, transport), 30% on wants (dining out, entertainment, subscriptions, holidays), 20% on savings and debt repayment. In high-cost UK cities, many people find 50% on needs is too tight. The key is direction: if savings are under 10%, something needs to shift.
Net worth = Total assets − Total liabilities. Tracking net worth monthly reveals whether financial decisions are working. A rising salary with rising lifestyle costs can produce zero net worth growth. A modest income with high savings rate produces compounding net worth growth. Direction matters more than absolute level.
Your savings rate determines how many years until financial independence more powerfully than any other variable. At 10% savings rate: 43 years to FI. At 25%: 32 years. At 50%: 17 years. At 70%: 8.5 years. Increasing savings rate from 10% to 25% cuts working years by 11. No investment return improvement achieves this impact.
Pay off debts in this order: (1) Any debt above 8% interest immediately; (2) High-interest consumer debt (credit cards, payday loans); (3) Car finance; (4) Student loans (Plan 2 effectively self-cancels at low income); (5) Mortgages (lowest-cost debt, tax-efficient in some circumstances). Emergency fund of 3 months expenses first, before extra debt repayment.
| Metric | UK Average / Benchmark | Target |
|---|---|---|
| Household savings rate | 9.4% of income (ONS 2026) | 20%+ |
| Average household debt (excl. mortgage) | £11,200 | £0 |
| Emergency fund size | 34% have under £1,000 | 3–6 months expenses |
| Pension contribution rate | 8% total (3% employer + 5% employee auto-enrol) | 15%+ of salary |
| Financial independence number | Varies by lifestyle | 25× annual expenses |
The standard recommendation is 20% of after-tax income, split between emergency fund (until 3–6 months expenses), pension contributions (maximising employer match first) and other savings/investments. In practice, anything above 10% is better than average. For FIRE (Financial Independence, Retire Early), 40–60%+ savings rates dramatically accelerate the timeline. Start with your employer pension match — this is a guaranteed 100% return on your contribution.
After-tax income is split: 50% to needs (essential housing, food, utilities, transport, insurance), 30% to wants (restaurants, entertainment, subscriptions, holidays), 20% to savings and debt repayment. This is a starting framework, not a rigid rule. In expensive cities (London, SE England), needs often consume 55–65% of income. The principle — conscious allocation across categories — matters more than the exact percentages.
FIRE number = Annual expenses × 25. Based on the 4% safe withdrawal rate (SWR): at 4% annual withdrawal from a well-diversified portfolio, historical data suggests the portfolio lasts indefinitely. To spend £30,000/year: FIRE number = £750,000. For UK residents, State Pension (currently £11,502.40/year from age 67) reduces the FIRE number required from investments. More conservative planners use 3–3.5% SWR (× 28–33 expenses).
