Even though it may seem complicated at first, the carpet cost calculator is easy and intuitive to use. Start by choosing the shape of your carpet and then follow these short steps and get your carpet's price calculated in no time.

1. RECTANGLE

For a rectangular carpet, put in the carpet's width and length in the carpet calculator. If you want to do the math on your own, use the following formula to calculate the area:

carpet area = carpet's width × carpet's length

Once you know the area, you can move on to calculating the cost. Put in the carpet's price per unit of area (remember to choose the unit of area your carpet is being sold in), and you will get the total cost thanks to the following equation:

carpet cost = carpet area × carpet price per unit

2. CIRCLE

For a circular carpet, the only value you need to put in the calculator is the radius of your carpet. Then, the carpet price calculator will work out the area with this equation:

carpet area = π × radius²

To calculate the carpet's cost, put in the price of the carpet per unit and the area you have just calculated in the following formula:

carpet cost = carpet area × carpet price per unit

3. ELLIPSE

If you're going for an oval carpet, give the calculator the lengths of the A-axis and the B-axis of the ellipsis, or use the following formula to calculate its area on your own:

carpet area = axis A × axis B × π

Now all that's left to do is using the price of the carpet per unit and the area's value to calculate the cost:

carpet cost = carpet area × carpet price per unit

4. PENTAGON

To calculate the area of a pentagonal carpet, put in the length of the pentagon's side so that the carpet cost calculator can work out its area. If you feel like doing the math on your own, you can use the following equation:

carpet area = side² × √(25 + 10√5) / 4

Next, use the area to calculate the cost:

carpet cost = carpet area × carpet price per unit

5. HEXAGON

Lastly, for a hexagonal carpet, you need to do the same thing you would do with a pentagon – give the calculator the hexagon's side's length, or use this formula to get its area on your own:

carpet area = 3/2 × √3 × side²

Calculating the cost is the same as in the previous cases:

carpet cost = carpet area × carpet price per unit

6. OTHER SHAPES

In the case of any other shapes, search for the shape and "area" here on Omni Calculator to help find the shape. Then, just like in the previous cases, simply multiply the price per unit of area by the carpet's area (or input it into the carpet price calculator):

carpet cost = carpet area × carpet price per unit

Knowing how to calculate carpet cost is one thing, but what about the installation? As with pretty much all construction projects, both amateurs and professionals are only human and, as such, are prone to making mistakes.

To make sure you don't waste gasoline going back and forth to the store for additional materials, consider buying at least 10% more of everything (note, we take this into account in this carpet cost estimator).

When shopping for a carpet, there is a number of factors worth considering other than just the carpet price. Here's a short guide of what you should think through before buying a carpet that will fill your needs perfectly.

• What is my budget? One of the first things to consider when wondering how to choose a carpet should be the cost. Carpets come in all shapes, colors, and price ranges. Unfortunately, the carpet price doesn't always depend on the quality or size - frequently, the place of origin, the prestige of the producer, or even such seemingly unimportant details as the trendiness of the pattern are the deciding factors that push the costs up. Estimate how much money you can spend on a carpet in advance to avoid the frustration and disappointment of looking at stores that are way out of your price range.

• Where will the carpet be, and what will it be exposed to? It's important to remember that the suitableness of a kind of carpet depends on the room it's going to be placed in. For example, a fluffy, luxurious carpet should do well in a bedroom, where you don't spend a lot of time. A living room carpet, on the other hand, should generally have shorter hairs and be made of more resilient fibers, as this is where people usually tend to spend most of their time indoors, and it's more prone to staining, tears, et cetera. Pets and children are other significant factors in buying a carpet.

• What are my needs, and what kind of carpet fibers would suit them best? Directly stemming from the point above, the type of fibers is something you should always look at. Natural fibers tend to be more expensive, but they can be less resilient, and, in some cases, they may even cause allergies. If you have pets, or if you're looking for a carpet for a hall where a lot of walking is being done, you may want to consider opting for synthetic fibers instead. Not all kinds of fibers are suitable for rooms with underfloor heating - if your house has that, make sure to choose a fiber that can handle it. Evaluate your needs and see what's available at your carpet store to get both the right carpet and the best carpet price.

• What about underlay? Carpet underlay is something people often forget about when talking about how to choose a carpet, but it's worth considering. Investing in a suitable underlay is especially important if you live above the ground floor and do a lot of walking, as this part of a carpet has a major influence on its acoustic qualities. Underlay is most often made out of rubber or foam. They also add an extra layer of insulation for your home.
