Goal breakdown calculator

Turn one big yearly goal into a number you can hit today. Enter your target and how long you have — this reverse-planning calculator does the monthly, weekly, and daily maths for you.

To reach 60,000 words for “Write my first book” in 12 months, aim for:

5,000words / month
1,154words / week
231words / work day
165words / every day

How to use the numbers

The “per work day” figure is usually the one to plan around — it assumes you rest some days, which is more honest than pretending you will show up every single day. Put that number on your calendar as a repeating task and protect it.

Treat the split as a baseline, not a contract. Front-load the months you know will be quiet, and lighten the ones around holidays or busy seasons. If you slip, come back and recalculate with what is left and the months remaining — the maths always gives you an honest fresh start.

Questions about breaking down goals

How does the goal breakdown calculator work?

It uses reverse planning: you enter the total you want to reach and the number of months you have, and it divides the total into monthly, weekly, and daily amounts. Working backwards from the finish line turns a big, abstract goal into a number you can actually hit today.

Should I divide a yearly goal evenly across 12 months?

Even division is a solid starting point, but real projects have ramp-up and seasonality. Use these numbers as a baseline, then front-load or protect lighter months around holidays and known busy periods.

What if I fall behind my monthly target?

Recalculate instead of abandoning the goal. Enter the amount you have left and the months remaining to get a fresh, honest daily number. Falling behind is a maths problem, not a reason to quit.

Is this calculator free?

Yes. It is completely free, runs entirely in your browser, and stores nothing. If you want the same breakdown to update automatically as you make progress, Goalzly does it on your iPhone and Apple Watch.
