Project Cost Calculator
Total the yarn, notions, and extras you enter, with an optional stitch-rate time estimate and selling-price scenario.
A calculator that adds entered yarn and notion amounts, estimates time from an entered stitch count and stitch rate, and compares an entered selling price with materials and estimated hours.
Fiber artists who want to check a material subtotal or explore a time and selling-price scenario from their own inputs.
The total is entered materials only. Optional time and selling-price outputs do not add labor cost, calculate net profit, or recommend a price.

How do I track yarn costs when buying from multiple sources?
Add each yarn purchase as a separate line with its quantity and price per skein. The calculator multiplies each pair of values and adds the results; it does not retrieve prices or verify receipts.
If you bought 2 skeins at one price and 4 at another, enter two lines so each quantity is multiplied by its matching price. The displayed yarn subtotal reflects only the values currently entered.
The calculator does not compare stores, retain purchase history, or add shipping, taxes, discounts, or fees automatically. Add an applicable amount as a notion or extra if you want it included, and keep source records separately.
What should I include in my craft project cost besides yarn?
The notions and extras section adds the amounts you enter for items such as buttons, zippers, stuffing, a pattern, packaging, shipping, taxes, or fees. It cannot identify missing costs or decide whether a reusable tool belongs in this project.
Review your own accounting scope before entering extras. A one-time material, a reusable tool, overhead, and a business expense are different categories even though this form can add any entered amount. The result remains an arithmetic subtotal, not a complete project or business budget.
The optional time estimate divides total stitches by the stitches-per-minute value you enter, then by 60. With a selling price, the tool subtracts entered materials and divides that remainder by estimated hours. It does not add labor cost, time setup or finishing work, determine net profit, or advise what anyone should charge.
What This Project Cost Calculator Totals
Enter each yarn quantity and price per skein, then add any notion or extra amounts you choose. The calculator multiplies and sums those entries into a material subtotal.
The optional time section estimates hours from total stitches and an entered stitches-per-minute rate. If you enter a selling price, the calculator subtracts the material subtotal and divides the remainder by estimated hours. It does not add a labor charge or recommend a price.
What Does the Result Represent?
The displayed total is the sum of the yarn and notion or extra amounts entered in the form. It is a material subtotal, not a complete accounting of every expense and not materials plus labor.
The optional selling-price outputs are scenario arithmetic. 'Selling price minus entered materials' is the remainder after the displayed material subtotal, and 'hourly remainder after entered materials' divides it by the displayed time estimate. The calculator has no cost-per-use, expected-use, target-rate, tax, fee, or overhead input.
How Project Cost Is Calculated
Yarn subtotal = the sum of each entered skein quantity multiplied by its entered price per skein. Notion subtotal = the sum of the entered notion or extra prices. The displayed total adds those two subtotals.
Estimated hours = entered total stitches ÷ entered stitches per minute ÷ 60. The visible time is labeled approximate and formatted to at most two decimals; the hourly remainder uses the unrounded time estimate. The model assumes one constant stitch rate and excludes work not represented by the stitch count.
When both estimated hours and a selling price are present, amount after materials = selling price − material subtotal, and effective hourly remainder = amount after materials ÷ estimated hours. Those values are not labor cost, net profit, or a fair-price calculation.
How to Use the Project Cost Calculator
Enter the quantity and price per skein for each yarn line. Add any one-time notion or extra amounts you want included. The calculator does not decide which expenses belong to the project, so review the entries yourself.
Optionally enter a total stitch count and your own stitches-per-minute assumption. Entering a selling price adds the after-materials and effective-hourly-remainder scenario; there is no hourly-rate, labor-cost, expected-use, or cost-per-use input.
Understanding Your Results
Use the material subtotal to check the arithmetic for the entries currently in the form. Missing or estimated expenses remain missing or estimated; the calculator does not verify receipts, quantities, currency conversion, or whether the list is complete.
Use the time and selling-price outputs only as sensitivity checks for your own inputs. Pricing, taxes, fees, legal requirements, overhead, demand, and compensation decisions are outside this calculator.
Input Checks
- ✓Use the same currency for all entries. Selecting a currency changes the displayed symbol; it does not convert amounts or exchange rates.
- ✓Enter shipping, taxes, fees, packaging, or other costs as extras only if you want them included in the material subtotal.
- ✓Measure your own stitch rate for a representative section if you use the time estimate; setup, finishing, corrections, and breaks require separate treatment.
- ✓Keep the entered selling price distinct from a recommended or accepted price. The calculator performs arithmetic on that scenario but does not evaluate the market or business obligations.
When to Use This Calculator
- ✓Adding the entered skein quantities and per-skein prices to the entered notion or extra amounts.
- ✓Estimating project time from an entered stitch count and personal stitches-per-minute assumption.
- ✓Comparing an entered selling-price scenario with the entered material subtotal and estimated time, without treating the result as a recommended price or complete profit calculation.
Common Mistakes to Avoid
- !Treating the displayed material subtotal as a complete project or business cost. It includes only the yarn and notion amounts you enter; taxes, shipping, fees, reusable tools, overhead, and other costs are absent unless you add them manually as extras.
- !Reading the time estimate as measured labor. It divides the entered total stitches by the entered stitches per minute and assumes that rate remains constant; it does not time the project or model setup, finishing, corrections, or breaks.
- !Reading the selling-price remainder as net profit or a pricing recommendation. It is only the entered selling price minus the entered material subtotal and does not subtract fees, taxes, overhead, or a labor charge.
Worked Example
Suppose you enter 3 skeins at $8 each and $6 of notions. The material subtotal is 3 × $8 + $6 = $30. If you also enter 12,000 stitches at 20 stitches per minute, the time estimate is 12,000 ÷ 20 ÷ 60 = 10 hours. With an entered selling price of $100, the displayed amount after materials is $100 − $30 = $70 and the effective hourly remainder is $70 ÷ 10 = $7 per hour. Neither figure includes fees, taxes, overhead, or a labor charge, and neither recommends a selling price.

Frequently Asked Questions
What does the project-cost total include?
It adds each entered skein quantity multiplied by its entered price per skein, plus the notion or extra amounts you enter. It is a material subtotal, not a complete budget and not materials plus labor.
Can the calculator compare making with buying?
No. It does not retrieve retail prices or decide whether making or buying is cheaper. You can compare the entered material subtotal with your own separately verified alternative.
How is the time estimate calculated?
Estimated hours equal the entered total stitches divided by the entered stitches per minute and then by 60. It assumes one constant rate and does not include setup, finishing, corrections, or breaks unless you account for them separately.
Does the calculator recommend a selling price?
No. You enter the selling-price scenario yourself. The calculator subtracts entered materials and, when estimated hours are available, divides that remainder by the hours; it does not add labor cost or determine a fair price.
What can I enter as a notion or extra?
You can manually label and enter one-time amounts such as buttons, zippers, stuffing, a pattern, packaging, shipping, taxes, or fees. The calculator cannot know which costs apply and includes only the amounts you add.
How should I choose stitches per minute?
Measure your own rate over a representative section of the intended stitch pattern and enter that assumption. Speed varies within a project, so treat the result as a simple estimate rather than a benchmark or recorded labor time.
