Please review my web application design

[antony_k]

Hi!
I need opinions and critique for my VAT calculator web app https://vatulator.com/



Is it convenient to calculate VAT on this calculator?

[pauland]

Nice design!

Caveats - not all countries have the same vat rate for all things and sometimes items are VAT exempt.

Vat applies to currencies so decimals/commas should be present (or another local number convention).

I toyed with the idea of having no buttons because I don't like the ambiguity of what the entry field represents, so you can do this without the need for any buttons and the user could enter any variable and have the other values change accordingly. I was too lazy to get the fonts or spacing exactly right.

Thanks for the tip about "no buttons". I will try to implement this option, the main thing is that users do not get confused in which field to enter the amount

I think the fields are clearly named and you can change ANY field!

Antony - What do you plan to do with this app?

As presented you offer no opportunity for What If scenarios.

I would prefer to see a set of sliders where the VAT can be dragged to a new value horizontally and the amount vertically.
A presentation like this might work on a phone:

<form>
    <input type="range" style="width:50%; height: 100%" id="capThou" data-filter="" data-unit="" min="0" max= "9" value="7" ignore="0" step="1"><strong><span id="capThouVal">7</span></strong>,000
    <input type="range" style="width:50%; height: 100%" id="capHun" data-filter="" data-unit="" min="0" max= "9" value="3" ignore="0" step="1"><strong><span id="capHunval">3</span></strong>00
    <input type="range" style="width:50%; height: 100%" id="capTen" data-filter="" data-unit="" min="0" max= "9" value="4" ignore="0" step="1"><strong><span id="capTenVal">4</span></strong>0
    <input type="range" style="width:50%; height: 100%" id="capUnit" data-filter="" data-unit="" min="0" max= "9" value="6" ignore="0" step="1"><strong><span id="capUnitVal">6</span>.<span id="capDecimal">38</span></strong>
</form>
<form>
    <input type="range" style="width:100%; height: 100%" id="capDeci" data-filter="" data-unit="" min="0" max= "99" value="38" ignore="0" step="1">
</form>

Obviously, you would still have an input box for both that can reflect the sliders' setting or adjust the sliders to the typed value.
An on-line example of a slider (almost) in action is http://www.vatcalculator.co.uk.

You need yours to be interactive to steal a march on the large number of simplistic calculators already out there.
This is the type of interactive i would promote: CSS3 Image Filter Generator.xar, which you won't be able to see or use without a Xara Desktop application.
So view here; http://acorn.xara.hosting/ImageFiltering/.

I think this is great, I just can't follow the steps to apply the generated code to an object. Any help would be gratefully accepted.

Edit: No sooner posted this and got it to work 100%. It was me not naming the image htmlclass="filter"

I made this calculator while learning css/html and javascript. Now I will improve the usability of the website.

Hi Antony,

In my opinion, you have to work on UI/UX part.
When I enter the amount and click on Add/Remove VAT button, then the new popup comes and it shows the calculated result.
I think it's not a proper way to show results. You can show results just below the calculator and remaining fields stays as it is.
Look at this one: vat-calc_dot_net

I just saw your web app it is good but for recent time I have used onlinevatcalculate_dot_com to calculate VAT. Please have a look on it and try to replicate it if it is possible.
