Question 1

How does the calculation work?

Accepted Answer

Income is converted to a value per millisecond. On each animation frame, the elapsed time since the start date is multiplied by this rate. For annual income, the divisor is 365.2425 × 24 × 3,600 × 1,000 ms, the duration of the mean Gregorian year.

Question 2

Why 4 decimal places?

Accepted Answer

The 4 decimal places make the counter's "tick" visible even for smaller incomes. For an income of $60,000/year, the rate per millisecond is ~$0.0000019, without decimal places, the counter would appear static. The 4 decimal places ensure visible animation.

Question 3

Does the calculation account for weekends and holidays?

Accepted Answer

No. The calculation is based on continuous chronological time, not worked hours. For a more accurate result, use hourly income and set only your working period as the interval. Or simply use it as a reference estimate.

Question 4

Can I use this tool for freelance work?

Accepted Answer

Yes. Set the income per hour (your freelance hourly rate) and define the start as the moment you began working on a project. The counter will show how much the time spent on that project is worth in monetary terms.

Question 5

What is the point of watching income accumulate in real time?

Accepted Answer

Real-time visualisation creates awareness of the value of working time. Behavioural economics research shows that concrete representations of value (like a growing number) affect decisions differently from abstract figures.

Question 6

How do I calculate my hourly rate from an annual salary?

Accepted Answer

Divide the gross annual salary by 2,080 (40 hours/week × 52 weeks). Example: $60,000/year ÷ 2,080 = ~$28.85/hour. This tool performs that conversion internally when you enter an annual salary.

Question 7

Does the counter pause when I switch tabs?

Accepted Answer

JavaScript in hidden tabs may have requestAnimationFrame throttled or paused by the browser to save battery. When you return to the tab, the calculation uses the real Date.now(), so the displayed value always reflects the total since the start date, only the animation may appear to "jump" on return.

Question 8

Can I use past dates as the start?

Accepted Answer

Yes. You can set any past date (start of month, start of year, employment anniversary) and see the total accumulated since then. For annual earnings of $60,000 starting on 1 January, you would already see a fraction proportional to the time elapsed in the year.
