Prioritization tool
Free MoSCoW Method Calculator for Product Teams
Sort your tasks and features into what you must do, should do, could do, and won’t do, so your team always knows what to focus on first.
MoSCoW Prioritization Calculator
Formula
Must have → Should have → Could have → Won’t have
Place every task into one of the four groups based on how important it is right now. The order tells you where to focus: finish the must-haves first, then work through the list as time and resources allow.
What is a MoSCoW Calculator?
A MoSCoW calculator sorts your tasks and features by priority into four clear groups, using the method Dai Clegg created at Oracle and the DSDM Agile framework made famous. Instead of a long, flat to-do list, you get a simple ranking that shows what’s essential, what’s important, what’s optional, and what to leave out.
Must have
What can’t you launch without?
These are the non-negotiables, the tasks your project fails without. If even one is missing, the release doesn’t work or isn’t usable. Keep this group small and honest, because labelling everything a “must” defeats the whole point.
Should have
What’s important but not vital?
These matter a lot and add real value, but the project can still launch without them for now. They’re painful to leave out, yet not. You do them right after the must-haves, once the essentials are covered.
Could have
What’s nice to include?
These are the nice-to-have extras, worth doing only if there’s time and budget. Leaving them out causes little harm. They’re the first things to drop when time runs out, which makes them a useful buffer.
Won’t have
What are you leaving out?
These are the tasks you agree not to do this time, at least for now. Naming them clearly is powerful: it sets expectations, prevents scope creep, and keeps everyone focused on what actually made the cut.
From scattered tasks to a clear plan
Prioritize the work your customers actually want
ProductBridge helps you collect feedback from across your channels, turn it into a clear roadmap, and share every release through a built-in changelog. MoSCoW helps you rank the work, and ProductBridge shows you which tasks customers care about most.
How to Use MoSCoW to Prioritize Your Work?
List the tasks or features you’re planning, then sort each one into must have, should have, could have, or won’t have. Work through them in that order, starting with must -haves and moving down only as time and resources allow.
The method works best when the whole team agrees on the labels together, since that’s where the real conversations about priority happen. A common rule of thumb is to keep must-haves to no more than about 60% of your effort, leaving room for the rest. Revisit the list as the project moves, because priorities often shift once work is going on.

MoSCoW calculator FAQ
Answers to common questions about using the MoSCoW prioritization method to evaluate features, organize backlogs, and make better product decisions.
What does MoSCoW stand for?
MoSCoW stands for Must have, Should have, Could have, and Won’t have — the four priority groups you sort work into. The lowercase o’s are only there to make the acronym pronounceable. The method was created by software developer Dai Clegg during his time at Oracle and became widely used through the DSDM Agile framework.
How many items should be must-haves?
Keep must-haves small. DSDM, the Agile framework that popularized MoSCoW, recommends that must-have work take up no more than about 60% of your team’s effort, leaving the rest for should-haves and could-haves. If everything is labeled a must, the ranking stops meaning anything — and the could-have buffer is what lets you absorb surprises without slipping the deadline.
When should I use MoSCoW prioritization?
MoSCoW works best when you have a fixed deadline or budget and need to agree on what fits within it. It’s ideal for planning a release, sprint, or project scope, especially when several people need to align priorities quickly. It’s less suited to comparing huge backlogs of similar items, where a scoring method works better.
How is MoSCoW different from RICE?
RICE scores each item using four factors: Reach, Impact, Confidence, and Effort, to produce a number you can rank. MoSCoW skips the math and simply groups work by how essential it is. RICE is more precise and better for comparing many items, while MoSCoW is faster, easier to explain, and better for aligning a team on scope.
Who should be involved in MoSCoW prioritization?
MoSCoW works best as a team effort rather than one person’s call. Including developers, designers, product owners, and key stakeholders means the priorities reflect both what customers need and what’s actually possible to build. It also stops any one person from stuffing the Must-have list. Often, the real value comes from the discussion itself, where people express disagreements about priority.
Can priorities change after you’ve set them?
Yes, MoSCoW is meant to be revisited, not fixed forever. As a project moves, new information, shifting deadlines, or customer feedback can change what matters most, so an item can move between categories. A “Won’t have” from one round often becomes a “Must have” later. Reviewing the list at key points keeps it accurate.
What are the limitations of the MoSCoW method?
MoSCoW has a few weak spots. It’s based on opinion, so people often disagree on what really counts as a “must”. It also only looks at how important a task is and how much time or effort it takes to build. Teams tend to mark too many things as must-haves, which slows the process. Because of this, MoSCoW works best when the team talks it through honestly, and often alongside another method that also weighs effort.
