How the Calculators Work

Formulas for the three calculators. The income tool converts an amount in one period into the others. Pricing and Take-Home are separate. Numbers stay in your browser. Income and Take-Home remember the form while this tab is open. Pricing can remember the last form on this device.

Not financial, tax, or legal advice. The income tool is gross pay only. Pricing and Take-Home use a tax percent only if you type one.

Step 1: Convert your input to an annual amount

Whatever period you enter, the calculator first normalizes it to a yearly figure:

• From year: use as-is
• From month: amount × 12
• From week: amount × weeks per year
• From day: amount × (days per week × weeks per year)
• From hour: amount × (hours per day × days per week × weeks per year)

Step 2: Break the annual amount into other periods

• Per month = annual ÷ 12
• Per week = annual ÷ weeks per year
• Per day = annual ÷ (days per week × weeks per year)
• Per hour = annual ÷ (hours per day × days per week × weeks per year)

Calculation modes

Advanced options

You can override the default hours per day, days per week, and weeks per year to match your own schedule — for example, a 4-day work week or 48 weeks of billable time per year. The formulas above stay the same; only the assumptions change.

Pricing calculator

The pricing calculator prices one product or job. Labor is not a cash cost. Profit is price minus expenses. Time turns that into profit per hour.

Product materials can be itemized. Each line is the share of what you paid for that pack, sheet, or roll:

• Line cost = (you paid) × (used ÷ in the pack)
• Used and in the pack must use the same units (sheets, grams, inches)
• If you paid is filled and used / in the pack are blank, the whole pack is counted
• Materials = sum of line costs

• Buffered materials = materials × (1 + buffer %)
• Fixed costs = buffered materials + packaging + shipping + other costs
• Fees = flat fee + price × fee %
• Expenses = fixed costs + fees
• Profit = price − expenses
• Tax set-aside = profit × tax % when profit is positive; otherwise $0
• Take-home = profit − tax set-aside (this can be negative)
• Hourly figures = amount ÷ (minutes / 60)

Suggested price:

• If you enter time and a desired hourly rate: suggested price = (target profit + costs + flat fee) ÷ (1 − fee %)
• Target profit = desired hourly × hours, or (desired hourly × hours) ÷ (1 − tax %) when “include tax in suggested price” is on
• If hourly rate or time is missing: suggested price is break-even = (costs + flat fee) ÷ (1 − fee %), which covers costs and fees only

Product vs Service uses the same formulas. Service hides packaging, shipping, the materials buffer, and the materials table. Use Project costs for a single total.

Take-home calculator

The take-home calculator starts from a take-home goal (sales you need) or from expected sales (take-home you get). Tax is a percent you type, applied after expenses. If take-home is negative, that number is shown.

From expected sales:

• Variable costs = gross × variable-cost %
• Profit = gross − expenses − variable costs
• Tax set-aside = profit × tax % when profit is positive; otherwise $0
• Reinvestment = after-tax profit × reinvest % when after-tax profit is positive; otherwise $0
• Take-home = after-tax profit − reinvestment

From a desired take-home greater than $0:

• Required gross = (take-home ÷ ((1 − tax %) × (1 − reinvest %)) + expenses) ÷ (1 − variable-cost %)

From a desired take-home of $0 or less (loss / break-even), tax and reinvestment are not applied:

• Required gross = (take-home + expenses) ÷ (1 − variable-cost %)
