The Honest Math on a $300-a-Month Automation

Someone quotes you $300 a month to take a chore off your plate, and the first thing you feel is a flinch. That's real money, every month, with no end date. Your gut says no before your head has run a single number.

The trouble with gut math here is that it's rigged against the tool. You're holding a clear, painful monthly bill in one hand and a vague pile of your own scattered time in the other. That clear number always wins the fear contest, even when it shouldn't.

So let's do the honest version instead. No pretending every saved minute turns into billable gold, and no hand-waving about "efficiency." Just a plain way to tell whether $300 pays for itself, plus the cases where it truly doesn't.

First, what an hour of yours is actually worth

You can't weigh a $300 bill without a price tag on your own time, and most owners don't have one handy. The reflex is to say your time is worth whatever you charge clients. That's part of it, but it's not the whole picture.

Think about it two ways. One, what you could earn in that hour doing the work only you can do, say you bill $120 an hour on the tools. Two, what you'd pay a person to take the chore instead, maybe $25 an hour for an assistant. The real value usually sits somewhere between those, and it climbs the later at night the chore happens.

Be honest that the 9 PM invoicing hour isn't worth zero just because nobody pays you for it. That's the hour you're not sleeping, not with family, not resting up for a full day tomorrow. For the math, pick one number you believe. We'll use $60 an hour as a middle-of-the-road example, but use yours.

The break-even line, in one sentence

Here's the whole formula: divide the monthly cost by your hourly value, and that's how many hours the tool has to save to pay for itself.

At $300 a month and $60 an hour, that's five hours a month. Roughly 75 minutes a week. So the only question that matters is whether the chore, plus the mistakes and follow-ups it creates, eats more than about an hour and a quarter of your week.

Run it at a few rates so you can find yourself on the line:

  • At $40 an hour, $300 needs to save 7.5 hours a month (under two hours a week).
  • At $60 an hour, it needs to save 5 hours a month.
  • At $100 an hour, it needs to save just 3 hours a month, about 45 minutes a week.

Notice which way this cuts. The more your time is worth, the less a tool has to do before it's a bargain. If you're the bottleneck in your own business, cheap tools that save real hours are some of the best money you'll spend.

The savings that don't show up on the invoice

Hours saved is the number you can see. The bigger wins are usually the ones you can't put on a line item, and it's worth naming them so you don't undercount the tool.

  • Fewer errors. Every time you retype an address or a phone number by hand, there's a chance it's wrong. A wrong address is a missed appointment, a callback, an apology. Machines are genuinely good at copying the same thing to five places without fat-fingering it.
  • Faster payment. An invoice that goes out the same day, instead of the following weekend, gets paid days sooner. Multiply that across a month and it's real cash in your account instead of stuck in your inbox.
  • Fewer dropped leads. A missed call that gets a text back, a quote that gets a gentle nudge, is a job you might otherwise have lost. One saved job a month often covers the whole bill by itself.
  • Less mental load. Harder to price, easy to feel. Not carrying a running checklist in your head all day is worth something, even if it never shows up in a spreadsheet.

A fair warning: don't stack these into a fantasy. It's tempting to add faster payment and fewer errors and one more job until the tool looks like it prints money. Count them, but count them lightly. The hours-saved number is the one you can defend, so lead with that and treat the rest as a cushion.

When the honest answer is don't

Automation isn't free even when the tool is cheap, and plenty of chores fail the math. Keep doing these by hand and don't feel bad about it.

  • The volume's too low. If the chore happens twice a month, a tool that saves ten minutes a shot will never clear $300. Save automation for the stuff that repeats.
  • It's judgement, not relay. Deciding which job to take, how to handle an upset customer, what to quote a tricky project, that's your work. Machines do the relay, people do the judgement. Don't automate the part that is the craft.
  • It's a one-off. Setting up a tool for a chore you'll do once or twice is just moving the work around. Do it by hand and move on.
  • It needs constant babysitting. If a tool saves you an hour but you spend 40 minutes a week checking that it worked, it's barely a tool. Ask hard questions about what running it actually costs.

There's no shame in a "not yet," either. A chore that's below the line today can cross it as you grow. Rerun the math in six months when the volume's higher.

Worth doing this week

No spreadsheet required, and no big decision. Twenty minutes with a rough number gets you most of the way.

  1. Pick one honest hourly value for your time and write it down. Middle of the road is fine.
  2. Divide the tool's monthly price by that number. That's your break-even in hours per month.
  3. Time the chore for one real week, follow-ups and fixes included, then compare it to the break-even.
  4. Add a modest cushion for the second-order stuff like faster payment and fewer errors, but keep it modest.
  5. If it clears the line with room to spare, try it. If it's close or below, wait and rerun the math later.

If you'd rather not do the arithmetic alone, that's part of what we do at TellRobots: help you figure out which chores are worth handing to a robot and which ones to keep. The formula above is yours either way. Run it before you say yes to any monthly bill, and you'll never get talked into the wrong one.
