What Is Backward Planning? A Complete Guide

TL;DR: Backward planning starts at your goal and works in reverse, asking "what must be true right before this happens?" at each step until you reach something you can do today. A 2017 Psychological Science study found backward planners completed more tasks, felt less time pressure, and had higher goal expectancy than forward planners. Use it by defining a specific outcome, repeatedly identifying the prerequisite step, and stopping once you reach an action you can take this week.

What Is Backward Planning?

Backward planning (also called reverse goal setting or backcasting) is a method where you start with your desired outcome and work backward to identify every step required to get there.

Instead of asking "What should I do first?" you ask "What needs to be true right before I reach my goal?" Then you repeat: "What needs to be true before that?" Keep going until you reach an action you can take today.

Why Backward Planning Works

Research published in Psychological Science (Park, Lu, & Hedgcock, 2017) found that people who planned backward completed more tasks and performed better than those who planned forward. The study showed three key benefits:

Greater motivation. Seeing the end goal first creates a sense of urgency and purpose. Every step exists because the goal needs it, not because it was convenient to write down.

Higher goal expectancy. Backward planning forces you to think concretely about what success looks like. When you can visualize the finish line, you're more confident you'll reach it.

Less time pressure. Forward plans tend to compress the most important work into the final stretch. Backward plans distribute work evenly because deadlines are derived from the goal, not guessed at.

Backward Planning vs Forward Planning

Here's how the two approaches compare side by side. For a deeper dive into the research behind this, see our full comparison of backward vs. forward planning.

Forward Planning	Backward Planning
Starts with today	Starts with the goal
Lists tasks chronologically	Lists prerequisites in reverse
Every item looks equally urgent	Every step has a clear reason
Empty list = done (until tomorrow)	Finished tree = goal reached
Drifts from the original goal	Can't drift, anchored to the outcome

How to Backward Plan Any Goal

Step 1: Define the outcome

Be specific. "Get fit" is not a goal. "Run a marathon in under 4 hours by December 2026" is a goal. Write it down as if it has already happened.

Step 2: Identify what must happen just before

Ask: "What needs to be true immediately before I achieve this?" For the marathon example: completing the 26.2-mile race. Before that: running a 20-mile training run. Before that: running a half-marathon. Keep going backward.

Step 3: Repeat until you reach today

Each answer becomes a milestone. Keep asking "what must happen before that?" until you reach something you can do this week, ideally today.

Step 4: Build your tree

Connect everything into a dependency chain. Some steps will branch (you might need both "improve nutrition" and "increase mileage" before a certain milestone). Each branch is a sub-goal with its own backward plan.

Step 5: Take the first step

The last thing you identified, the one closest to today, is your starting point. Do it now. For a complete walkthrough of the reverse goal setting method with a real example and a downloadable tree, see Reverse Goal Setting: The Backward Planning Method Explained.

Common Mistakes

Setting vague goals. "Start a business" is not specific enough. "Launch an MVP with 100 paying users by Q3" forces concrete backward steps.

Skipping levels. Going from "become CEO" directly to "update LinkedIn" skips years of milestones. Break it down until each step is absurdly small.

Never revisiting the plan. Goals change. Your backward plan should be a living document that adapts as you learn.

Tools for Backward Planning

You can backward plan with pen and paper using our free reverse goal setting template. For a digital version, tools that visualize the dependency tree make it easier. GoalBranch is purpose-built for this: you type a goal and it generates the backward plan automatically, showing every branch on an infinite canvas you can pan, zoom, and edit. See how it stacks up against other options in our roundup of the best AI goal planners.

The Bottom Line

Forward planning is fine for known, short-term tasks. But for ambitious goals, the ones that have survived three phones in your notes app, backward planning is the only direction that can't drift. Start at the finish line and work backward until your next 20-minute step is sitting in front of you.
