## Introduction

The **Retail Discount Calculator** is a free
web
application for calculating retail sales discounts to assist in
making well informed purchasing decisions.

Designed to work on any device the **Retail Discount
Calculator** can be conveniently used on a smartphone while
shopping to efficiently reveal the actual out-of-pocket
cost for sales items. This allows you to remain focused on the
*value* of the potential purchase at hand while reducing the
probability of buyer's
remorse, thus making for a more pleasurable overall shopping
experience.

Are you a budget minded consumer?

Is shopping and finding deals more a sport than a necessity for you?

Do you find yourself frequently contemplating any of the following?

- Did I find a good deal,
*or not*? - How much of a
*deal*? - How much is this actually
*costing me*? - How many, if any, can I
*afford*? - Should I get more than
*one*?

If you answered "*Yes*" to one or more of these questions then
you'll find the **Retail Discount Calculator**
will be an essential tool to accompany you on your shopping adventures.

### Post-decision Dissonance

Lucky you, you've just come upon a *one day only* unadvertised
in store special on shoes! Who doesn't need shoes? Right? Alrighty,
down to business, let's see, **35% Off** the regular
price, not too bad. Having been lured in you take stock of the sale.
Lots of name brands and variety, regular prices range from **63.49** to **249.99**, so you start
digging for deals.

Hmmm, wait a second, are these prices overinflated?79.99for these shoes seems expensive, I'm sure I've seen these for60.00at another store across town. Did I find a good deal,or not?

Guess what just happened? Cognitive dissonance just kicked in. The mental stress of your contradicting monetary values would likely cause you to pass on the now speculative savings, possibly even the entire sale. Assuming you were right about their competitor's pricing, or even the brand similarity for that matter, it is in fact a savings.

Now had you had the **Retail Discount Calculator**
at hand you would have realized this in seconds. Perhaps not enough to
purchase this particular item, but it would have put your mind at ease
and you would most likely keep looking for bargains with confidence.

WHOA! Now here's a find, I've always wanted a pair of these! Now how much are they, YES! only89.99, I know these are well over100.00everywhere else!

With the **Retail Discount Calculator** in hand
you can efficiently conclude exactly how much they'll cost and how much
you could potentially save. Input the **89.99** list
price, then the **35%** discount and *viola*,
that's **31.50** off the list price with a subtotal
of **58.49**, **15%** tax is
**8.77** and the grand total is **
67.27**, that's a Total Savings: **$36.22**. Now
you can make a well informed purchasing decision on this item with next
to no mental effort expended on the math!

Perhaps the only decision now is do you get all three colors. Too easy,
just update the **Qty:** field to **3** and once again, *viola*,
that's **95.49** off the combined list price for a
subtotal of **175.48**. The **15%**
tax is **26.32** and the grand total is **201.80**, that's a Total Savings: **
$108.66**. No more undue mental stress or buyer's remorse for you,
just the *deals*!

Looking at a mattress set on sale at **700.00** off the
**2,249.99** list price. Is it a good deal? Can you
afford it? What's your out-of-pocket cost? ... again, too easy, enter
the list price then the discounted amount. That's a **
31.1112%** discount with a subtotal of **1,549.99**.
The **15%** tax is **232.50** and
the grand total is **1,782.49**, that's a Total
Savings: **$805.00**.

What the? ... how is that a$805.00total savings if it's700.00off?

The difference is the tax that's not charged on the discount.
The **15%** tax saved on **700.00**
is **105.00**, that's real dollars saved that remain
in your pockets after the sale. So it is indeed a **$805.00**
savings.

### Do You ...

- Want to do hypothetical analysis?
- Like to haggle?

Simply change the discounted dollar amount or the subtotal to play with the numbers and haggle with confidence.

You can also use the **Retail Discount Calculator**
to quickly tabulate the tax inclusive costs of regular list price purchases
too. Need to know how much *seven* items at **13.67** each with a **15%** tax rate will cost?
Simply input the list price and quantity to reveal a subtotal of **95.69**, tax of **14.35** with a
grand total of **$110.04.**

## Getting Started

### Accessing the Discount Calculator

Open the following URL in your web browser: http://linuxnet.ca/discount/

If your browser supports off-line browsing you can use this feature to save a local copy of this application for off-line personal use. Consult your web browser's help and or documentation for details.

### Configuring Tax

The first step is to configure the tax. You can set the tax name and
the tax rate by clicking or tapping on the tax label, The default is HST
at 15%, to change the default click or tap on the **HST 15%:** label
and you'll be prompted for the tax label name followed by the tax amount.
A **15%** tax rate is inputed as **0.15** and **7%** would be entered in
as **0.07** et cetera.

Only one tax is currently supported. If you have multiple taxes you can come up with a single rate by figuring out the tax inclusive total for a 10.00 subtotal in your area then use the following formula:

**Formula:**

Total / Subtotal - 1 = Tax Rate

**Example:**

11.50 / 10.00 - 1 = 0.15

If you would like to see multiple tax fields supported in future releases
of the **Retail Discount Calculator** then
contact me at the email address provided at the end of this help document
requesting this feature and if I receive enough requests I'll add it
in. Please provide me with the relevant taxation details of a typical
retail sale in your Province, State or municipality so I'll have a better
idea of what's required to implement this.
