Our aims
CalcBudget publishes practical, plain-English information about everyday UK money topics: budgeting, saving, borrowing, tax on pay and property, and paying off debt. Our aim is to help readers understand the numbers behind their decisions, not to tell them what to do. Every page should be accurate, clear about its limits and easy to check.
Research and sources
We base factual statements on primary and official sources wherever possible, mainly GOV.UK, HMRC, the Bank of England, the Office for National Statistics and MoneyHelper, the government-backed guidance service. We link to the specific source page within the text so readers can check the detail. We do not publish statistics or figures that we cannot source, and we do not present estimates as facts.
Worked examples
Worked examples are written to show how a calculation works with realistic figures. They are illustrations, not real people or real cases. Every figure in a worked example is checked, either by running it through the relevant CalcBudget calculator or by calculating it by hand, before publication.
Writing standards
- We write in UK English for UK readers, and we say when a rule applies only to part of the UK.
- We explain terms such as APR, Personal Allowance or Stamp Duty bands when we first use them.
- We state assumptions and limitations clearly, especially on calculator pages.
- We do not use testimonials, invented case studies or exaggerated claims.
- We do not recommend specific financial products or providers.
Independence and advertising
CalcBudget is funded by advertising served by Google AdSense. Advertising is kept separate from our content: advertisers do not see or influence what we write, and we do not accept payment for coverage or links. We do not currently use affiliate links. If that changes, we will label them clearly and update this policy.
Reviews and updates
Pages that depend on tax rates, allowances or thresholds are reviewed at the start of each tax year in April and whenever a relevant change is announced. Other guides are reviewed at least once a year. Each guide shows when it was last updated. When we update a page we check every rate, figure and link on it.
Corrections
If we find or are told about an error, we correct it promptly. Where a correction changes a calculator result or a significant fact, we note it on the page. See our corrections policy for details, and use our contact page to report a problem.
Not advice
Our content is general information, not personal financial, tax, mortgage, legal or investment advice. We encourage readers to check important figures with official sources and to seek regulated advice where it is needed.
