Talk:Compound interest

Rewrite

I have started rewriting this over-long, meandering, rambling article. I have rewritten the early part, re-using as much of the previous content as possible, but the rest of it still needs simplifying and condensing into something more easily digestible. Jonathan G. G.

There is inconsistent use of the variables in the math section. I find it confusing that the variable i is used for interest rate, when it can be confused with the interest amount. Likewise P is used for Payment, and elsewhere for Principal. --Gfsheppard (talk) 23:10, 16 October 2016 (UTC)

I moved some of the sections around, notably trying to keep all the math under one heading. The Examples section is confusing, as it contains information that is not clearly examples, but applications of compounding interest.Gfsheppard (talk) 22:58, 17 October 2016 (UTC)

The calculation section especially should be minimized. And this article should not focus on loans so much. — Preceding unsigned comment added by Dashparabola (talk • contribs) 23:56, 17 August 2020 (UTC)

History - Roman and Common Law

I took a cursory glance at a scanned version of this cited source online and while the edition of the encyclopedia I found does have an entry on compound interest, it does not make mention of or imply the claim that "Compound interest when charged by lenders was once regarded as the worst kind of usury and was severely condemned by Roman law and the common laws of many other countries."

I'm not suggesting an edit be made to the article proper because, by my own admission, my own research into the source was done very quickly and it may to the contrary of my own claim be stated in another edition of the encyclopedia, but I was unable to find it myself in the one edition that I did find. My sincere apologies if I am incorrect or if this post is made in poor etiquette but I believe if the citation does not in fact corroborate such a claim it may be worth further investigation in order to strengthen the statement in question or otherwise disprove it. 2001:1970:4B9E:C701:41FF:9BA2:91EF:F028 (talk) 20:45, 20 July 2023 (UTC)

Error messages for formulae

The formulae on this page aren't displaying correctly. Instead, each formula has been replaced by an error message in large red font. It's not my browser, as the formulae on other Wiki pages display correctly. An example on this page is the standard compounding formula A=P(1+r/n)^nt, which instead shows the following:

Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "http://localhost:6011/en.wikipedia.org/v1/":): {\displaystyle A=P\left(1+\frac{r}{n}\right)^{nt}}

I don't know how to edit formulae, so I'm posting this alert. My first "talk" contribution, so I hope I'm doing this right. Emperorsnewtogs (talk) 03:23, 19 April 2024 (UTC)

Replaced bare reference; saving note for posterity

I saw that InternetArchiveBot had labeled the url for this reference as a permanent dead link. Because it was a bare reference, I replaced it entirely. However, the reference also included a lengthy note that I considered reproducing via the quote parameter of the cite web template, or perhaps as a footnote in the article, but I hesitated because the last sentence makes an assertion that I imagine needs a citation:

The Interest Act specifies that interest is not recoverable unless the mortgage loan contains a statement showing the rate of interest chargeable, "calculated yearly or half-yearly, not in advance." In practice, banks use the half-yearly rate.

I don't have the time now to track this down, and am also not sure how necessary people might find the note. But if someone else wants to restore this note in some way, feel free! – spida-tarbell ❀ (talk) (contribs) 04:58, 15 August 2024 (UTC)

Negative amortization

Are there any reasons not to merge the article for negative amortization with this one? Does it represent a meaningfully different concept? Jokojis (talk) 03:38, 22 August 2024 (UTC)
