# A Complete Guide to Calculating Your Test Automation ROI - Canonical: https://33rdsquare.com/a-complete-guide-to-calculating-your-test-automation-roi/ - Published: 2024-03-06 - Author: Brian Lucas - Categories: [App & Browser Testing Automation](https://33rdsquare.com/category/browser/browser-testing/) --- Hey there! As an expert in test automation with over 10 years of experience validating software on thousands of real devices and browsers, I know one question always comes up when making the case for automation: _"What‘s the ROI?"_ It‘s completely reasonable for stakeholders to ask this. Implementing test automation requires considerable upfront investment – in tools, framework creation, maintenance processes, and more. Convincing decision-makers means **providing tangible ROI calculations** tied to bottom line impacts. After quantifying automation ROI many times, I can guide you through simple formulas to project cost/time savings plus efficiency gains. By relating these numbers to business outcomes, we clearly demonstrate automation‘s value. **Here‘s what we‘ll cover in this guide:** - Overview of Test Automation ROI - ROI Calculation Formulas - Efficiency ROI Metrics - Factors That Increase Your Automation ROI - Common ROI Measurement Mistakes - Why Testing on Real Devices Boosts ROI Let‘s dive in and crunch the numbers! ## What Exactly is Test Automation ROI? First, **what does ROI mean?** ROI calculates your "return on investment" – how much you gain or lose by putting money into something. > ROI (%) = (Gain from Investment – Cost of Investment) / Cost of Investment x 100 Positive ROI means your returns exceeded costs. Your investment pays off. **For test automation ROI specifically:** - "Gains" come from **saving testing time/costs** by automating manual processes - "Investment" includes **building, maintaining, expanding** automated testing ## Calculating Your Test Automation ROI Figuring exact ROI gives proof automation drives efficiencies, saving time and money longer term. Here are two easy formulas to demonstrate automation ROI: ### 1. Basic Cost/Time Savings ROI This measures direct savings over manual testing: ``` ROI % = (Savings from Automation - Costs of Automation) / Costs x 100 ``` - **Savings** = Hours reduced running tests automatically - **Costs** = Hours invested in framework creation, maintenance, test coding For example: ``` Manual testing time = 500 hours With automation: Initial setup: 80 hours Test coding: 200 hours Maintenance: 60 hours (monthly) Total Automation Costs: 80 + 200 + 60 = 340 hours Total Savings: 500 - 340 = 160 hours ROI % = (Savings - Costs) / Costs x 100 = (160 hours - 340 hours) / 340 hours x 100 = -53% ``` This basic ROI shows -$53 return per $1 spent on automation – **not yet breaking even**. But as tests expand over 6 months, picture 10X more test runs: ``` Manual testing time = 500 hours x 6 months = 3,000 hours Total Automation Costs: 340 hours x 6 months = 2,040 hours New ROI % = (3,000 hrs - 2,040 hrs) / 2,040 hrs x 100 = 47% ROI ``` Now automation achieves **47% ROI** – paying back almost $0.50 per $1 invested! ### 2. Efficiency Gain ROI This directly measures improvements in testing velocity: ``` Efficiency Gain % = (Manual Hours - Automation Hours) / Manual Hours x 100 ``` Revisiting the first example: ``` Manual testing time = 500 hours Automation testing time = 340 hours Efficiency Gain % = (500 - 340) / 500 x 100 = 32% ``` So automation boosted testing efficiency by **32%** here. The efficiency formula helps show productivity benefits beyond just cost savings. Leadership loves productivity stats! ## What Factors Increase Automation ROI? Many variables impact achieving positive ROI from test automation: ### More Tests & Test Runs The **volume of tests** run drives cost savings. If it takes 5 minutes to manually test a feature but 90 seconds with automation – those 4 saved minutes per test add up quick! | Tests | Daily Runs | Months | Manual Testing Time | Automation Time | Savings | | --- | --- | --- | --- | --- | --- | | 100 | 1 | 1 | 750 hours | 250 hours | 500 hours | | 500 | 1 | 1 | 3,750 hours | 1,250 hours | 2,500 hours | | 1000 | 4 | 6 | 9,000 hours | 3,000 hours | 6,000 hours | More test cases + frequent test runs make automation way more valuable. ### Lower Test Failure Rates Bugs in test scripts themselves hamper ROI by slowing everything down for troubleshooting. **20% test failure rates** from flaky tests or script issues creates tons of unplanned maintenance. Attaining **5% or less failures** through solid test design is ideal to maximize ROI. ### Coverage Expansion Over Time The **broader your test coverage**, the more confident you can release changes with less risk. Prioritizing different test types like security, performance, edge cases proves automation‘s worth. Plan **continual coverage expansion** in your ROI projections. ### Agility & Feature Release Velocity The **competitive advantage** automation testing provides cannot be overstated. Your team‘s ability to release faster depends on test automation scalability. This speed translates directly into growth and revenue. Consider ROI in the context of **enabling business objectives** like agility. ## Common Test Automation ROI Mistakes Based on frequently seeing teams calculate ROI, here are some common missteps: ### Not Budgeting Enough for Maintenance The maintenance costs of automated testing often surprises first-timers. Be comprehensive in assessing needs for **failure investigation, script updates, test additions/deletions** over 12+ months. This investment is key for long-term returns. ### Assuming Full Manual Testing Replacement It‘s super rare for automation to wholly replace manual efforts. Humans still shine at **exploratory testing, spot checks, complex test case design, final verifications**. Calculate automation ROI complementing skilled QA talent rather than replacing them. ### Forgetting Infrastructure Costs All the tools, services and environments needed to run automation require capital and operational expenses. Cloud platform subscriptions, 3rd party software, test lab costs contribute heavily to overall automation spending. ### Isolating ROI from Business Goals While efficiency metrics matter, also relate automation ROI to **customer growth, risk reduction, faster release cycles, improved uptime**. Connect testing capacity to business outcomes for maximum buy-in. ## Why Real Devices Are Key for Maximizing Automation ROI Here‘s an ROI consideration I see teams often overlook: Are you truly testing for the real world with automation? Simulators and emulators **do not reliably replicate** the vast device fragmentation and variations real users have. With [over 9000 distinct device configurations](https://www.browserstack.com/guide/software-testing-on-real-devices) globally accessing apps and websites, software has to work properly across countless combinations. Factors like cellular networks, outdated OS versions, foreign locales all impact application stability and UX. **Emulators miss many of these real-world variables.** Without real devices representing user conditions, defects inevitably reach customers, destroying experience perception. **This directly lowers automation ROI** – you can run a million automated tests, but if not validating against real devices, ship astonishingly bad software, undermining quality, speed and cost benefits automation should provide. I cannot stress enough how **critical real device testing** is for maximizing test automation ROI and outcomes. Cloud platforms like [BrowserStack](https://browserstack.com) enable affordable, scalable access to thousands of real mobile devices and browsers for test automation. Consider ROI calculations assuming real device cloud access vs. simulators – the business justification confirmation becomes abundantly clear. ## Let‘s Talk About Your Automation Testing ROI I hope walking through sample ROI calculations and considerations brings clarity on projecting test automation benefits.
