How do I make a logic model for free?

Use the generator above: keep or rename the Inputs, Activities, Outputs, Outcomes, and Impact columns, then add an item for each resource, activity, output, and outcome. The diagram renders instantly and downloads as a scalable SVG — no sign-up required.

What are the five parts of a logic model?

The standard columns are Inputs (resources), Activities (what the program does), Outputs (direct countable products), Outcomes (changes in knowledge, skills, or behavior), and Impact (the long-term change). Some models split outcomes into short, medium, and long term, or add a Situation column at the start.

Can I add or rename columns?

Yes. Every column title is editable, and you can add or remove columns and items. Use it for a five-column model, a six-column version with short/medium/long-term outcomes, or a custom framework — the diagram lays out whatever columns you provide.

What is the difference between a logic model and a theory of change?

A logic model is a linear chain from inputs to impact that describes how a specific program operates — ideal for planning and evaluation. A theory of change is broader and works backward from a long-term goal, mapping the pathways and preconditions to reach it. Many proposals include both.

Can I export the logic model for a grant proposal?

Yes. Download the diagram as an SVG — a vector format that stays sharp at any size and drops straight into a proposal, report, poster, or slide deck, or opens in Illustrator or Inkscape for final edits. Every version is free to download.

What is a logic model?

A logic model is a diagram that lays out how a program is meant to work — the chain of reasoning from the resources you put in to the change you hope to see. It reads left to right through a series of linked columns, usually Inputs, Activities, Outputs, Outcomes, and Impact, connected by "if-then" arrows: if we have these inputs, then we can run these activities; if we run these activities, then we produce these outputs; and so on. Logic models are a staple of grant proposals, program planning, and evaluation because they make a program’s theory of change explicit on a single page. This generator builds one for you — type your columns and items on the left and the exact SVG updates instantly on the right.

The columns of a logic model

Inputs — the resources invested: staff, funding, materials, partners, and time.
Activities — what the program actually does with those inputs: workshops, services, outreach.
Outputs — the direct, countable products of the activities: sessions delivered, people reached.
Outcomes — the changes in knowledge, skills, or behavior that result, often split into short, medium, and long term.
Impact — the long-term, higher-level change the program contributes to in the community or field.

How to make your logic model

Start from the default Inputs → Activities → Outputs → Outcomes → Impact columns, or rename them to match your framework.
Add an item to each column for every resource, activity, output, or outcome — add or remove items and whole columns as you need.
Note your assumptions and external factors in the field below the chain — these are part of a complete logic model.

Logic model vs theory of change vs conceptual framework

These three are related but distinct. A logic model is the most operational: a linear chain from inputs to impact, ideal for planning and evaluating a specific program. A theory of change is broader and works backward from a long-term goal, mapping the pathways and preconditions needed to reach it. A conceptual framework, more common in academic research, diagrams the variables and relationships behind a study rather than a program. If you are planning or evaluating a program, a logic model is usually what a funder asks for; for a research study, use the conceptual framework generator instead.

Logic models in a grant proposal

Most funders now expect a logic model in the proposal, and it often anchors the evaluation plan. A strong one keeps each column tight — a handful of clear items, not a wall of text — and makes the arrows defensible so a reviewer can trace how your activities lead to the outcomes you promise. Spell out assumptions and external factors so the model does not overstate what the program alone can achieve. This tool renders the diagram from the columns you enter; pair it with a conceptual framework for the underlying theory, or a PRISMA flow diagram and forest plot if your proposal reviews prior evidence.
