What this calculator works out
This calculator adds yarn, pattern, needles, notions and postage into a total project cost, showing the yarn separately from everything else.
Separating them is the point. Yarn usually dominates, but the extras on a first project can rival it — and they are mostly one-off purchases that later projects reuse.
Project costs
Before you total it up
- Yarn cost is balls multiplied by price. Use the Knitting Yarn Calculator to establish the ball count first.
- Needles are a one-off for that size. If you already own them, enter zero.
- Notions covers buttons, zips, stitch markers, a tapestry needle and anything else the pattern lists.
- Postage is easy to forget and is frequently charged per shop rather than per order.
A first jumper buys the needles, the stitch markers and the tapestry needle alongside the yarn. The second buys only yarn and a pattern. Judging whether knitting is expensive on the first project is like judging cycling by the cost of the first bicycle — and it is why the calculator separates the two.
How this calculator works
A sum with the yarn isolated:
Yarn = balls × cost per ball
Total = yarn + pattern + needles + notions + postageThe result shows yarn, pattern and everything else as three figures, which makes it easy to see what a repeat project would cost — usually just the yarn and, for a different design, the pattern.
Worked example: a small project
Using the default figures — 8 balls at £5.50, a £4.00 pattern, no needles, £3.50 of notions, no postage:
- Yarn: £44.00
- Total: £51.50
Yarn is 85% of it, which is typical once the needles are owned. Add £12 for a pair of needles on a first project and the total becomes £63.50, with the yarn share falling to 69%. Comparing that against a shop-bought equivalent is a reasonable exercise, provided the comparison is with something of similar fibre and construction rather than with the cheapest available jumper.
Common mistakes
- Counting needles on every project. They are reusable across many.
- Forgetting postage. Ordering from several shops multiplies it.
- Underestimating notions. Buttons for a cardigan can cost more than a ball of yarn.
- Comparing against the cheapest shop equivalent. Compare like fibre with like fibre.
- Ignoring the yarn already in stock. Using it costs nothing further.
Frequently asked questions
Is knitting cheaper than buying?
Rarely, for a plain garment compared against mass-produced equivalents. Frequently, compared against a hand-knit or high-quality natural fibre garment of the same specification. Most knitters do it for the making rather than the saving, and framing it as a cost comparison misses what the hobby actually provides.
How can I reduce the cost?
Substituting a cheaper yarn of the same weight and fibre content is the largest lever — the Yarn Substitution Checker covers doing it safely. Free patterns are widely available and many are excellent. Buying yarn in sales, using stash, and choosing projects that use less yarn all help. Charity shops occasionally yield good yarn.
What equipment do I actually need to start?
A pair of needles in the pattern's size, the yarn, a tapestry needle for weaving in ends, and scissors. Stitch markers are useful and can be improvised from scrap yarn. Everything else — row counters, blocking mats, interchangeable sets — is convenience rather than necessity and can wait.
Should I buy an interchangeable needle set?
It is worth it once you are knitting regularly and have found yourself buying individual sizes repeatedly. For a first project it is a substantial cost for a capability you may not use. Many knitters buy singly for the first few projects and switch to a set when the pattern of use is clear.
