You can be busy every day and still not make money. The fix isn’t working harder — it’s knowing your numbers: how many jobs you need, how much of your paid time is actually billable, and what a realistic week looks like on the truck. These four free calculators walk that path in order, from the floor (just covering costs) up to a real income goal. No signup, no app, and the math is shown so you can check it.

These are planning aids, not legal or tax advice. The outputs are estimates built from the numbers you type in. Your figures stay in your browser.

Start with the floor: break-even jobs

Every service business has two kinds of cost. Fixed costs show up whether you work or not — insurance, truck payment, software, phone, marketing. Variable costs happen per job — fuel, materials, disposal, blade wear, a helper’s hours.

The number that ties them together is contribution margin per job:

Contribution margin per job = average job price − variable cost per job

That’s the money each job leaves on the table to chip away at your fixed costs. If you charge $65 for a mow and it costs you $20 in fuel, materials, and wear, each job contributes $45. Once your jobs have contributed enough to cover all your fixed costs, you’ve broken even — every job after that is profit.

So the break-even job count is just:

Break-even jobs = fixed costs ÷ contribution margin per job

If your fixed costs are $4,000 a month and each job contributes $45, you need about 89 jobs a month before you’ve made a dime of profit. That single number is useful, but it’s hard to act on a monthly figure. The break-even jobs calculator breaks it down into the units you actually schedule with — jobs per month, per week, and per day — using the standard conventions of about 4.33 weeks per month and about 21.7 working days a month (a 5-day week; it offers a 6-day toggle for trades that work Saturdays). Eighty-nine jobs a month is about 21 a week, or roughly 4 a day — now it’s a target you can put on a schedule.

The same tool adds a small profit ladder — break-even, then +10%, +20%, and +50% above it — so you can see what each cushion buys you in extra jobs and dollars. A common rule of thumb treats a 10% cushion as a basic safety buffer and 20% as comfortable, though the right number depends on your business. If you type in what one crew can realistically handle, it also flags when your costs require more jobs than a single crew can deliver — your cue to raise price, cut variable cost, or add capacity, not to grind harder.

The lesson: lower your fixed costs or raise your contribution margin and the break-even count drops fast. Charging $10 more per job moves the floor more than working an extra hour does.

The reality check: billable hours and utilization

Here’s the trap that catches new operators: you assume a 40-hour week is 40 billable hours. It never is. You drive between jobs, you quote, you invoice, you fix the mower, you take a day off. The hours a customer actually pays for are your billable hours, and the share of your paid time they represent is your utilization rate:

Utilization = billable hours ÷ paid hours

If a tech is paid for 40 hours but only 26 of them are on a customer’s property billing, that’s 65% utilization — and 14 hours a week are going to driving, admin, and downtime. That gap is normal. The point is to see it, because it’s usually the biggest hidden leak in a service business, and travel time is often the largest single piece.

What counts as healthy? Across field-service sources, a commonly cited target band is roughly 60–80%, with 65–70% considered solid and 75–80% where strong operators land. Below about 50% you’re underused (you have room to sell more work); push much above 85% for long and you’re heading toward burnout and missed jobs. The technician utilization calculator takes your paid hours and your travel, admin, and PTO buckets, returns one utilization percentage with a band label, and — the part the KPI blog posts skip — tells you how many more jobs a day your crew could absorb before it’s full. That’s the honest answer to “do I need another tech?”: a number, not a gut feeling. It rolls up a multi-tech crew, too, so you can read the whole shop at once.

Why this sits next to break-even: break-even tells you how many jobs you need; utilization tells you whether your crew has the room to do them. If break-even says 21 jobs a week and your utilization math says one crew tops out at 18, you’ve found your real bottleneck before it finds you.

From a job count to an actual day

A weekly job target is still just a number until it’s laid out as a route. Stops clustered in one neighborhood take far less drive time than the same count scattered across town, and a day that looks fine on a spreadsheet can fall apart when the windshield time is real.

The route day planner turns your week into a printable worksheet you can clip to a clipboard or stick on the dash. You type your stops in once; they group by day, sort by zone and time window, and roll up into per-day and per-crew totals. It deliberately does not call a map API or auto-optimize your route — drive time is a field you fill in yourself — so nothing about your customers leaves your device. It does flag a day as overloaded when the stop count runs past operator-typical ranges (it uses soft defaults like about 14 stops a day for a solo mower, 22 for a two-person lawn crew, 12 for pest control, 6 for residential cleaning, and 8 for handyman work). Those are starting points, not rules — your route, lots, and service mix decide your real limit, so the warnings nudge, they never block.

Why this comes third: once you know the jobs you need (A) and the room you have (B), the planner is where the plan meets the calendar. It’s also the one member that’s a worksheet, not a calculator — and it saves your week to this device only, so you can come back to it next week and clear it in one click.

Aim higher: turn a take-home goal into a plan

Break-even answers “how many jobs to stop losing money.” The other side of the coin is “how many jobs to hit the income I actually want.” It’s the same algebra, run backward from a profit target:

Required jobs = (take-home goal + fixed costs) ÷ contribution margin per job

The lawn-care profit & revenue goal planner back-solves that into jobs per month, per week, and an hours-per-week load, and shows a revenue ladder — what $50k, $100k, $150k, and $250k in take-home each require — side by side, with your own target dropped in next to them. Seeing four goals at once is the part the single-answer incumbents miss: it turns a vague ambition into a concrete weekly pace.

Two honesty features keep the plan from becoming a fantasy. First, seasonality: many lawn and outdoor trades only run part of the year, so the planner divides the annual job count across your active months (it defaults to about 8) instead of pretending you mow in January — assuming 12 months can overstate your real weekly capacity by a third or more for northern operators. Second, a capacity sanity check: it warns when your goal pushes you past about 90% utilization and flags it as impossible above 100%, because no crew bills every hour it’s paid for. A sensitivity table then shows what a small price change (±$10) or a variable-cost change (±$5) actually does to the job count — usually more than you’d guess.

A note on defaults. This planner ships with lawn-care-flavored starting numbers (for example, around $60 a mow and $18 variable cost) drawn from 2026 industry ranges. They’re illustrative defaults to get you moving, not a price recommendation — type in your own and the math follows.

How to use these tools together

Run them in order; each one feeds the next.

Set the floor. Start with the break-even jobs calculator. Enter your fixed costs, average job price, and variable cost per job. Write down the jobs-per-week number — that’s the minimum your week has to clear.
Check the room. Open the technician utilization calculator and enter your paid hours and your travel, admin, and PTO. Compare the jobs-per-day headroom it gives you against the weekly target from step 1. If the headroom is smaller than the target, that’s your bottleneck — fix it before you chase more bookings.
Lay out the week. Take the job count into the route day planner, drop your stops into days and zones, and print the sheet. The per-day warnings tell you fast whether the plan is realistic or just optimistic.
Aim past break-even. When the floor is covered, switch to the lawn-care profit & revenue goal planner and back-solve the jobs needed to hit a real take-home number — then sanity-check it against the same capacity math from step 2.

One more connection worth making: every one of these tools gets easier the moment your prices are right. Raising your average job price lifts your contribution margin, which drops your break-even count and shrinks the jobs you need to hit any goal. If your pricing isn’t dialed in yet, start one step earlier with the job pricing tools — then come back here to plan the volume.

A reminder on the numbers. These are planning estimates, not legal, tax, or financial advice. They’re built entirely from the figures you enter and the plain formulas shown above, using common service-business conventions (about 4.33 weeks a month, about 21.7 working days a month, a 60–80% utilization band). Industry benchmarks vary by trade, region, and year — treat the defaults as a starting point, not a promise. Nothing you type leaves your browser.
