About TopicDrill
Numbers you can act on, from a site that shows its working
Money decisions are serious, so we treat them that way. Every calculator runs on the standard, transparent formula for its topic, and each page documents the method, the assumptions, and the date it was last reviewed. Where a number depends on tax bands or contribution limits, we check it against the official source and link to it.
- Transparent formula and assumptions on every page
- Content reviewed and stamped with a last-updated date
- Figures checked against official US and UK sources
- 100% free, with no sign-up and no data collected
Frequently asked questions
Are all the calculators free to use?
Yes. Every calculator and guide on TopicDrill is completely free, with no sign-up, account or payment required. You can use any tool as many times as you like.
Do I have to share any personal or financial data?
No. The calculators run in your browser and we do not ask you to register or hand over personal details to get a result. You stay in control of your numbers.
How accurate are the results?
Each tool uses the standard financial formula for its topic, and we show the method and assumptions on the page. Results are reliable estimates for planning, but they are not a quote or an offer from any lender or provider.
Which countries do the calculators support?
Most tools work for any currency and are tuned for United States and United Kingdom rules where tax or contribution limits apply. Each page states the market and figures it uses so you know what applies to you.
Is this financial advice?
No. Our calculators and guides are for general information and education only. For decisions that affect your money, speak to a qualified professional who can consider your full situation.
