Contact CompoundCalc
One address handles everything: corrections, questions about how a calculator works, privacy requests, and suggestions for tools that should exist but do not.

Messages are read by a person. Most get a reply within a few working days; corrections are looked at first.
What to include, by type of message
| If you are writing about | Please include |
|---|---|
| A number that looks wrong | The page address, the figure you saw, the inputs you used, and what you calculated instead. This is the fastest possible way to get something fixed. |
| A calculator behaving oddly | The page, your browser and device, and the exact inputs. A screenshot helps. |
| A tool that should exist | The question you were trying to answer. Requests phrased as a real question are far more useful than a feature name. |
| Privacy or data | What you would like done. Note that the site holds no accounts and stores nothing you type — see the Privacy Policy. |
| Embedding or reuse | Where you want to use it. The embed page and section 6 of the Terms cover most cases already. |
What cannot be answered
CompoundCalc is not a regulated adviser and cannot answer personal financial questions — which fund to buy, whether to overpay a mortgage, whether a pension or an ISA suits you, whether your plan is enough. Those depend on your tax position, timeline, obligations and risk tolerance, none of which a website can assess. For those, speak to a qualified professional in your country. The disclaimer explains the boundary in full.
Unsolicited guest-post pitches, link-exchange offers and paid-placement requests are declined without reply. The site publishes no sponsored content and no affiliate links, as set out in the editorial policy.
Before you write
Three pages answer most incoming questions:
- How we calculate — the exact formula, compounding convention and contribution timing each tool uses.
- FAQ — the recurring questions about rates, frequency and what the outputs mean.
- Common mistakes — if a result looks too high or too low, the reason is usually one of these seven.
Corrections
Reporting an error is a favour to every future reader, and it is treated that way. Numerical reports are checked against an independent reference calculation, and if the number was wrong it is corrected and the page's update date changed. Where the correction changes the conclusion, a note is left on the page saying what changed. The process is documented in the editorial policy.
