Use this free yarn cost calculator to estimate what you will spend on yarn before starting a crochet project. Enter your required quantity, the amount in one ball and its price. The tool rounds the purchase to whole balls, shows the estimated cost and reports the quantity left over at those figures.

Your estimate
Enter your details, then select Calculate.
An estimate of yarn purchase cost only. Delivery, taxes, discounts, dye-lot availability and other materials are not included. No currency conversion is performed.
How this yarn cost calculator works
Enter the required quantity after adding any spare-yarn allowance. If you need 650 g and each ball contains 100 g, you need 7 whole balls. The estimate assumes every ball has the same quantity and price. Use the currency in which you will buy the yarn.

How to use the yarn cost calculator
Choose grams, metres or yards, then use that same unit for both quantity fields. Enter the total yarn needed after including your chosen allowance. Next, read the amount in one ball from the yarn label and enter the actual price per ball. Select the currency used by the shop and press Calculate.
The currency selector changes the money display. It does not fetch prices or convert exchange rates. If you are buying in Pakistani rupees, enter the price in PKR and choose PKR. Do not enter a dollar amount and select another currency expecting the number to be converted.
A yarn cost calculator example: seven whole balls
Suppose your project requires 650 g including spare yarn. Each ball holds 100 g and costs 5 dollars. Dividing 650 by 100 gives 6.5, so you need seven whole balls. The yarn cost calculator returns a yarn purchase cost of 35 dollars and an estimated spare quantity of 50 g.
That spare amount comes from buying 700 g for a requirement of 650 g. It is not another allowance added by the tool. If the pattern asks for several colours, calculate each colour separately because a leftover amount in one colour cannot always replace yarn needed in another.
Use the label quantity consistently
Some patterns list weight while others give length. A 100 g ball is not automatically a fixed number of metres: fibre, thickness and construction vary. When your pattern specifies length, use the ball’s labelled length in the same unit. Avoid comparing a requirement in yards with the number of metres on the label.
For an area-based estimate made from your own sample, start with the Yarn Quantity Calculator. It estimates weight, length and whole balls from a measured swatch. The budget tool then lets you compare a supplier’s actual price without assuming that a yarn substitution has the same fabric or gauge.
What belongs outside the yarn budget
This calculation includes yarn at one quantity and price per ball. Add shipping, applicable taxes, buttons, lining, stuffing and packaging separately when they apply. A promotion may use bundles, a minimum spend or a different price for each colour; check the actual basket before treating the estimate as your final bill.
If a pack contains several balls, either convert the pack price to the price of one matching ball or treat the entire pack as the purchasable unit. In the second method, enter the total quantity in the pack and the pack price together. Do not combine a pack price with a single-ball quantity.
Yarn cost calculator questions
Should I include a spare-yarn percentage? Enter the requirement after adding any allowance you choose. The tool does not silently add another percentage. Swatch size, finishing, borders and your own tension affect how much yarn you use. The Craft Yarn Council’s gauge guidance explains why a sample matters when comparing your fabric with a pattern.
Can I subtract yarn I already own? You can enter only the remaining amount you need to buy, provided your existing yarn is suitable for the project. Check the colour and dye lot before combining supplies.
Can this price a finished handmade item? Yarn purchase cost is one input. Use the Crochet Pricing Calculator to include working time, overhead and your chosen selling fees. Browse the other free crochet tools when planning the size and stitch count.
Three checks before using a yarn cost calculator result
1. Calculate each colour separately
Suppose a project needs two hundred and fifty grams of one colour and fifty grams of another. If both are sold in one-hundred-gram balls, you need three balls of the first colour and one of the second. Adding the requirements together and buying three unspecified balls would leave the second colour unaccounted for.
Run the yarn cost calculator once for each colour or distinct yarn. Keep each ball quantity and unit price beside its result, then add the subtotals. If the supplier charges different prices for particular shades, use the actual price for each shade rather than assuming the range has one uniform cost.
2. Compare packs on the same basis
A pack containing four one-hundred-gram balls provides four hundred grams. When entering that pack as one purchasable unit, use four hundred grams and the full pack price together. The required number of packs will then be rounded as packs, not individual balls. Confirm that the pack contains the colours and quantities your project needs.
The yarn cost calculator cannot identify an offer’s conditions. A bundle discount, minimum order or mixed-colour pack may change what you actually buy. Compare the estimated quantity with the supplier’s product details and basket before deciding which option meets the project requirement.
3. Separate spare yarn from other costs
If your requirement already includes an allowance, the leftover quantity reported after rounding is additional yarn resulting from whole-ball purchasing. It is not a second allowance inserted by the calculator. Keep the original requirement and purchased quantity separately in your notes so that the difference is easy to explain.
Use the yarn cost calculator for the yarn subtotal, then record shipping and any other applicable costs separately. Yarn already in your cupboard can reduce the amount to buy only when it is suitable for the design and quantity required. Check the label, colour and condition before subtracting it from a new purchase plan. The cheapest basket is useful only if its contents will work for your project.
