https://morphyca.com/workcalc-manual/
Work Calculator is a business calculator app that compiles calculations used daily in accounting, shops, and on-site. The key layout and the way calculations are performed in the order they are pressed are designed to match desktop business calculators.
It can be used to check the tax-inclusive amount on invoices, set prices based on purchase costs, record and summarize the working hours of part-time and temporary employees. All functions are free for the first 30 days. There are no ads.
■ Usage Similar to Desktop Business Calculators
There is a 00 key, and calculations are performed in the order they are pressed (1 + 2 × 3 = 9). AC, C, and ⌫ are grouped in the right column to prevent accidental deletion when pressing 0 or 00.
Results are displayed comma-separated, with the ten-thousands unit added below, such as "1,234,567".
■ Tax-Inclusive/Tax-Exclusive
Select the tax rate (8% or 10%) in the display section, enter the amount, and press "Tax-Inclusive" or "Tax-Exclusive". If the tax rate is 10%, then 1,000 yen including tax is 1,100 yen. Pressing the same key again will display the consumption tax (100 yen).
You can choose to round down, round to the nearest yen, or round up for fractions of less than 1 yen in the consumption tax.
■ 8% and 10% Totaling
The "Tax Calculation" menu allows you to add up the amounts for 8% and 10% separately, and display the pre-tax, consumption tax, tax-inclusive, and total amounts for each tax rate. This is useful for checking receipts or purchase amounts that mix 8% and 10%.
Since the consumption tax is calculated by rounding off the fractional amount for each item, there may be a difference of 1 yen compared to the total amount calculated on an invoice.
■ GT, Constant Calculation, Memory
The answer obtained with "=" is automatically added to GT, and you can view the total using the GT key.
Pressing "=" repeatedly will repeat the same calculation (100 + 50 = = = → 150, 200, 250). If you fix the multiplier using the "Constant" key (e.g., "× 0.7"), you can simply enter an amount and press "=" to get the amount multiplied by 70%. There are also M+, M-, and MR memory functions.
■ Cost, Selling Price, Gross Profit
Entering two of the cost, selling price, and gross profit margin will calculate the remaining one (enter the percentage in the "Gross Profit" key). For example, if the cost is 1,000 yen and the gross profit margin is 30%, the selling price is 1,429 yen. The gross profit margin is a percentage of the selling price, so it will be a different amount than 1,300 yen (cost plus 30%).
On the "Cost, Selling Price, Gross Profit" screen in the menu, you can also calculate the selling price from the cost percentage, or the gross profit margin from the selling price and cost.
■ Time Calculation (Time Mode)
Add and subtract hours and minutes directly. Adding 7:30 to 8:45 gives 16:15, and the decimal "16.25 hours" is displayed below, so you can use it directly for hourly wage calculations.
Pressing 845 gives 8:45, and pressing 1830 gives 18:30. Entering clock-in, clock-out, and break times will show working hours, and entering regular hours and clock-out times will show time after regular hours (overtime). If the clock-out time is before the clock-in time, it will be calculated as work spanning across two days, so it can also be used for night shifts from 22:00 to 6:00 the next day.
■ Work Recording and Monthly Summary
While looking at a paper time card, enter clock-in, clock-out, and break times for each person with dates. The date advances with "Record and advance to next day," making it easy to enter everything at the end of the month. Days where work is split into day and night shifts can be entered twice.
For each closing date (last day of the month, 15th, 20th, 25th), the system calculates the number of working days, actual working hours, night shift (10 PM to 5 AM), and overtime (more than 8 hours per day and more than 40 hours per week). For those who entered their hourly wage, an estimated amount is displayed, with each line representing the regular wage, night shift premium, overtime premium, and transportation expenses. It also accommodates those with different hourly wages for weekends and holidays.
Time is calculated in 1-minute increments; there is no rounding down to the nearest 15 minutes. Records can be sent as text or saved as a CSV file. All records can be exported and imported when changing devices. The amounts are estimates and do not include overtime exceeding 60 hours per month, holiday premiums, taxes, or insurance.
■ History
Calculated formulas and results are saved in the history. Tapping a row allows you to correct intermediate numbers and recalculate. You can also add notes about clients and product names, save, and return results to the calculator from here.
■ Conversion
Converts between tsubo ⇔ m², tatami ⇔ m² (1 tatami = 1.62 m² in real estate listings), shaku ⇔ cm, yards, feet, inches, and miles. Gradient is calculated from height and horizontal distance as a sun slope, fraction (e.g., 1/10), percentage, or angle.
■ Data Storage Location
No account registration is required. History, settings, and work records are stored only on your smartphone; internet access is only used for purchases.
The screen brightness and darkness switch according to your smartphone settings.
■ Pricing
All features are free for the first 30 days. After the trial period, basic arithmetic operations, tax-inclusive/tax-exclusive calculations, and history viewing remain free. History and notes are not deleted.
To continue using the following features, a one-time purchase of 480 yen (tax included) is required. There are no monthly fees or additional payments.

• 8% and 10% totals
• Cost, selling price, gross profit
• Edit, memo, and save historical figures
• Time mode

• Checking the purchase amount with mixed 8% and 10% tax rates
• Calculating the selling price from the purchase price
• Recording part-time and temporary worker hours and estimating monthly totals and salaries
• Checking your own working hours and overtime hours
