The 100 in 100 Days Goal Calculator

A hundred customers in a hundred days sounds fine until you divide it. Put in the target, the deadline and what you have actually logged so far. You get tomorrow morning's number, the pace you are really on, and the distance between the two.

Your run

Just a label. The maths is the same whichever you pick.
100
How many you want by the deadline.
100
Calendar days from the start to the deadline. A hundred is the usual pick.
2
Days you know you will not work. They come out of the maths instead of being wished away.
30
Where you are right now. Zero if you start tomorrow.
22
Only the ones that already happened. Not the maybes sitting in your inbox.

Catching up costs 1.56 a day across the 50 working days left, up from 1.4. Cheap to fix tomorrow. Expensive to fix in three weeks.

How to use the number

The figure in the black panel is the only one worth remembering. Everything else on this page exists to argue for it.

Take it literally, and take it daily. If the calculator says 1.4 customers a day, nobody is closing 1.4 customers between nine and ten in the morning. What it means is that the work behind 1.4 customers has to happen today, and that work is countable even on the days the result is not. Put your real reply and close rates into the outreach volume estimator and 1.4 turns into a number of conversations, which is a thing you can put in a calendar and finish.

Log results the day they land. Pace rebuilt from memory on a Sunday evening is always kinder than pace written down on a Tuesday, and the kindness is the problem. A tracker that flatters you is a diary.

Then read the second number, the one that says what your daily target has to become. That is the price of the mornings you sat out, spread across the mornings you have left. Every skipped day nudges it up a little. Far more useful than guilt.

Why a daily number beats a quarterly one

Quarterly goals fail for a dull reason. They tell you nothing until it is too late to do anything with it. Sixty days of no work looks identical to sixty days of good work when the only checkpoint is a review in December, so you find out you were wrong at the exact moment you can no longer fix it. A daily number can be proved wrong by lunchtime.

The bigger thing a daily number does is take the deciding away. Working out what to do about marketing is a tax founders pay every morning, usually at the hour their attention was already promised to the product. There are only four things you can do to get customers: reach out to people who already know you, post something in public where strangers can find it, reach out to strangers, or pay to get in front of people. Alex Hormozi calls that set the Core 4 in his book $100M Leads. Choose one on Sunday and the Monday morning has no argument left in it. The guide to the Core 4 explains what each one costs you, and the marketing channel quiz will pick one for you if you would rather not think about it.

Daily also survives being wrong. Miss a Tuesday on a quarterly plan and nothing visible happens, so Wednesday goes too, and by the following Monday the plan is a document rather than a habit. Miss a Tuesday here and the number moves in front of you, small enough to fix by Wednesday lunchtime. Keep the correction cheap and the correction actually gets made.

About those rest days

Seven days a week is how founders get to day nine. Rest days come out of the division instead of being wished away, so two a week on a hundred day run leaves roughly 71 working days and pushes the daily number up to match. Better to see that on day one than to find it in week six while optimising a channel you have already run eleven times.

If the number that comes back looks impossible, it probably is. That is useful, not a reason to close the tab. You can move the deadline out or lower the target. The third option, getting more results out of the same effort, is the only one that does not cost you the goal, and it is most of what the first 100 customers playbook is about.

Questions

What counts as a result?

Anything you would defend out loud. Paying customers, signed clients, people who typed their own email into the box. Impressions are not results and neither are follows. If the thing you are counting cannot say no to you, count something else.

Why working days instead of calendar days?

Because you will not work every day, and a plan that quietly assumes you will is broken on day one. Rest days come out of the division, so the number you see is the one to hit on the days you do show up. Two rest days a week over a hundred days leaves about 71 working days.

I am behind. How bad is it?

Look at the number you need from here, not the size of the gap. Going from 1.4 a day to 1.6 is a normal week with earlier mornings. Going from 1.4 to 5 means the deadline is the thing to move, not your effort. Knowing which of the two you are looking at on day thirty is worth more than any streak.

Is 100 customers in 100 days realistic for a solo founder?

It depends almost entirely on your price and on where the customers come from. A hundred customers at €10 a month, found through people you already know plus some posting in public, is a hard but ordinary hundred days. A hundred at €500 a month is a different business with a different sales process, and the daily number will look nothing like it. Put your own reply and close rates through the outreach volume estimator before you decide the target was fair.

Can I use this for something other than customers?

Yes. Subscribers, replies, demos booked, downloads, anything you can count once a day without arguing with yourself about what counts. The maths does not care about the unit, so pick the one that is hardest to fake.

What happens if I miss a whole week?

Push the days-gone slider up by seven, leave the logged number alone, and read the new daily target. On a hundred day run at 1.4 a day, a week off lifts it to roughly 1.56. That is about eleven percent more work every remaining morning. Real, survivable, and much smaller than the dread that usually follows a missed week.

The number is easy. Hitting it on a Tuesday in week seven is not.
