We are the MonoTape team. When you are paid by the hour, your monthly income is never a fixed number. Some weeks you pick up extra shifts, some weeks you work fewer hours, and by the time payday arrives you are not quite sure what to expect. Working it out on a calculator means multiplying rate by hours over and over, and the running total disappears the moment you start the next week. In this article we show how labeling each chunk of work lets you build a monthly income figure that stays put.
Rate times hours, done many times, loses its history
The math itself is simple: $16 an hour times the hours you worked. The trouble is that you do it again and again across a month, and a plain calculator only ever shows the last answer. Multiply 16 * 22 for week one, then 16 * 18 for week two, and the first result is already gone. To get the month, you have to remember every week's hours and add them back up.
That is exactly how people misjudge a paycheck. A calculator does not record that 22 was last week's hours, so there is nothing to look back at — and nothing to correct when a shift gets added or cut. You are rebuilding the whole month from memory every time.
One labeled line per week, summed into the month
In MonoTape you put the rate on its own line, then add one labeled line per week for rate times hours. The monthly total is just the sum of those weekly lines, and it stays visible the whole time.
Now you can watch your income build as the month goes on, and you always know how many hours each week contributed. Because the rate lives on its own line, you can see the whole month at a glance instead of trusting that you added it right. The breakdown is the record.
When your rate changes or a shift gets added
Maybe you get a raise to $17, or a shift moves and week three becomes 28 hours. With a plain calculator that means redoing every multiplication. In MonoTape you edit the rate line once and every week that references it recalculates, or you fix the single week whose hours changed. The monthly total updates on its own.
Tracking an hourly income is a tool problem, not a discipline problem. Put the rate on a line, log each week as rate times hours, watch the monthly total, and edit only what moved. Your paycheck stops being a surprise and becomes a number you can see coming.

How do I total a month when my hours vary?
Add one labeled line per week as rate times hours, then sum the weekly lines into a month line. Each week stays on the tape, so the monthly total is always visible and you can see what each week contributed.
What happens when my hourly rate changes?
Put the rate on its own line and reference it from each week. Edit the rate once and every week that uses it recalculates automatically, and so does the monthly total.
Can I track several months?
Yes. Keep each month as a labeled line on the tape so you can look back and compare. Because everything is saved on your device, the history stays put for you to return to.
Is it free?
Yes. Labeled calculations, references, auto-recalculation, and tape-style history — every feature mentioned here is free. It works on both iPhone and Android, and your data stays on your device.
