Valtrinity vs CalculatorSoup

CalculatorSoup is a long-running calculator site, with copyright dates from 2006 on its pages. It describes itself as a comprehensive resource of professionally designed and programmed online calculators, and it is especially deep on maths. Valtrinity has calculators too, with a strong group of UK and US money tools, but it is a wider collection that also holds converters, text, PDF, image, developer and website tools.

Valtrinity is a rival of CalculatorSoup, so weigh our view with that in mind. We read their pages on 18 October 2026 and list every one at the bottom of this page. CalculatorSoup does not state how many calculators it has, so we do not compare totals. Instead we compare what each site lists, and where CalculatorSoup goes further, particularly in maths, physics and chemistry, we say so.

At a glance

Maths and everyday calculators

CalculatorSoup's home page groups its mathematics calculators into fractions, general maths, algebra, percentages, statistics, discrete maths, plane and solid geometry, trigonometry and word problems. It also lists practical groups for time and date, words, construction, conversions, technology, physics, chemistry, games and sports, health and miscellaneous calculators. Its description adds that many calculator pages show the work or equations behind the answer.

Valtrinity covers the everyday ground: percentage, percentage change, fraction, decimal to fraction, average, ratio, GCD and LCM, prime numbers, Pythagoras, area and volume, and a long list of unit converters. We now have algebra, trigonometry, statistics, physics and chemistry calculators, but CalculatorSoup covers more topics within each subject, such as discrete maths, so for a student going deep it is still worth a look.

Money, tax and the UK

CalculatorSoup lists financial groups for loans, interest and APR, time value of money, financial ratios, sales and retail, depreciation, saving and investing, and money, pay and taxes. Its home page does not say which country's rules the tax calculators follow, and we have not tested them.

Valtrinity has UK income tax, take-home pay, stamp duty (with versions for commercial and historic purchases), capital gains tax, dividend tax, inheritance tax, student loan repayment, redundancy pay, holiday pay, VAT and pension calculators, and US versions of the main money tools. Our rule is that any figure that changes over time carries a review date and a link to an official source.

Cost, accounts and adverts

We found no plan, price or sign-in link on the CalculatorSoup pages we read. Its privacy policy says it may allow third-party companies, including ad networks, to serve adverts and collect information about visits, so adverts are part of the site. Its Terms of Use restrict commercial use of the website except for its widgets.

Valtrinity's calculators need no account and have no daily count. We show adverts on tool pages unless you have Unlimited, which is £29.99 a month or £249 a year with a 3-day trial. Unlimited raises the cap on server lookups to 1,000 a day and on writing runs to 100 a day. Lookups for visitors are limited to 5 a day, or 10 with an account, and none of this affects the calculators.

Widgets, requests and languages

CalculatorSoup offers financial calculator widgets, which its home page aims at financial institutions and financial professionals, and invites requests and suggestions for new calculators. Valtrinity has no widgets, so a site owner who wants to embed a calculator should look at CalculatorSoup first.

We found no language switcher on the CalculatorSoup home page. Valtrinity's menus, buttons and headings come in nine languages: English, German, French, Spanish, Italian, Dutch, Portuguese, Polish and Japanese. The explanation under each tool stays in English. We have not tested either site with a screen reader.

Which should you choose?

Choose CalculatorSoup if you want a deep maths reference, with algebra, statistics, discrete maths, geometry and trigonometry calculators, physics and chemistry groups, or financial calculator widgets for another site. Choose Valtrinity if you need UK money calculators such as take-home pay, stamp duty or student loan repayments, or if your task also needs text, PDF, image, developer or website tools on the same site.
