Yarn Cost Calculator
How many balls your project needs — and what it will cost.
Buy 7 balls · total 59.50
Leftover 140 yd/m. Use the same length unit for both fields; the total is in whatever currency you enter.
How to use
- Enter how much yarn the project needs — take this from your pattern or the Yarn Yardage estimator.
- Enter the length of a single ball (from the ball band) and its price.
- Read how many balls to buy — always rounded up — plus the total cost and how much yarn is left over.
- The price works in any currency; whatever you type in is what the total comes out in.
Good to know
- Balls always round up because you cannot buy part of a skein — the leftover figure tells you how much spare you will have.
- Buy from the same dye lot for a whole project, and consider one extra ball for safety — leftover yarn is easier to live with than running short mid-row.
- Length per ball, not weight, drives how far the yarn goes — two 50 g balls can hold very different yardage.
FAQ
- Why does it always round up?
- Shops sell whole balls, so if a project needs 6.4 balls you have to buy 7. The calculator rounds up and shows the leftover so you know how much spare you are paying for.
- What currency is the total in?
- Whatever you enter. The price field is just a number, so if you type the price in your own currency the total comes out in the same currency.
- How do I find how much yarn my project needs?
- Your pattern usually lists total yardage. If it does not, estimate it with the Yarn Yardage calculator from the project type and yarn weight, then bring that figure here.
