Calculators

# Put numbers on what you already suspect

Four simple calculators. Enter your numbers, see the result and see the whole calculation: every formula and every assumption is in plain sight. It is an estimate, not a promise.

- Runs in your browser
- Formulas and assumptions in plain sight
- A link to share the result

## The calculators

Return

### [attendo ROI](https://attendo.me/en/calculators/roi)

The hours and money your team gets back when it stops hunting for data, retyping service reports and chasing approvals.

**You need:** Office and field staff, hours a week and cost per hour

CMMS

### [Corrective vs. preventive maintenance](https://attendo.me/en/calculators/corrective-vs-preventive-maintenance)

What unplanned breakdowns cost you a year, compared with a preventive maintenance plan you set yourself.

**You need:** Breakdowns a year, downtime hours, cost of downtime and cost of repair

Ticketing

### [Cost of missing the SLA](https://attendo.me/en/calculators/sla-breach-cost)

What late tickets add up to per month and per year: contract penalties and the hours spent explaining and compensating.

**You need:** Tickets a month, percentage breached, penalty and handling hours

Field Service

### [Service reports and paperwork](https://attendo.me/en/calculators/paper-work-orders)

The office hours spent retyping service reports and the money waiting to be invoiced in the meantime.

**You need:** Service reports a month, office minutes per report, cost per hour and days to invoice

## Your numbers, and the math in plain sight

A calculator that hides its assumptions is no use for making decisions. These show all of theirs.

### Only with your numbers

The starting values are an example so you do not start from a blank page, not an industry average. Replace them with yours.

### The math, in plain sight

Under each result is the formula with your numbers. You can repeat it in a spreadsheet.

### Cautious on purpose

We leave out what is hard to measure, like the customer who does not renew. If the numbers work without it, even better.

### Nothing is stored unless you ask

The calculation runs in your browser. Your numbers only leave it if you share the link or ask us to email you the calculation.

## Frequently asked questions

### Are these calculations reliable?

They are as good as the numbers you enter. The formulas are simple and in plain sight, so you can check them or repeat them in a spreadsheet. It is an estimate, not a promise of results.

### Where do the sample values come from?

They are a starting point so the calculator does not start empty, not industry averages or figures from a study. In each calculator we explain why we chose each one. Replace them with yours.

### Why are attendo’s prices not shown?

Because we do not publish prices on the website. If you already have a proposal, enter its annual cost in the ROI calculator: you will see the return and the months to recover it.

### Can I share the result?

Yes. The values stay in the page address. With the “Copy link with my numbers” button, anyone who opens the link sees the same calculation.

### Do you store the data I enter?

Not unless you ask us to email you the calculation. The calculation runs in your browser and your numbers only travel in the link if you choose to share it. If you ask for the calculation by email, we keep your email address with the values and the result to send it to you.

## Shall we go over it with your numbers?

Tell us what you want to solve and bring the numbers from the calculator. We will show you attendo with your case and go over together which part of the result is realistic.
