7 Grant Writing Mistakes That Kill Your Funding Chances | Grantly Blog

After analyzing thousands of grant applications, we identified the patterns that separate funded proposals from rejected ones. Here are the 7 most common mistakes and exactly how to fix them.

Not Following Guidelines Exactly

Critical

The number one reason proposals are rejected before they are even read: they do not follow the funder formatting and submission guidelines. This includes page limits, font sizes, margin requirements, and required sections.

Real Example:

A 2024 NIH proposal was rejected for being 0.5 pages over the limit. No exceptions are made.

How to Fix It:

Create a compliance checklist from the solicitation. Check every requirement before submission. Use tools that auto-validate formatting.

Weak Problem Statement

High

The problem statement is the foundation of your entire proposal. If reviewers do not understand or believe in the problem, nothing else matters. Too many proposals jump straight to solutions without establishing the need.

Real Example:

We need funding to develop a new AI tool. vs. Current grant discovery tools miss 60% of relevant opportunities, costing researchers an estimated $2.3B annually in unfunded projects.

How to Fix It:

Start with data. Quantify the problem with citations. Make the reader feel the urgency before presenting your solution.

Unrealistic Budget

High

Budgets that are too low suggest you do not understand the scope. Budgets that are too high suggest you are padding. Every line item needs justification.

Real Example:

A $500K proposal with $50K for personnel and $400K for equipment raised red flags about the team commitment.

How to Fix It:

Research standard rates for your field. Justify every line item. Include indirect costs. Get quotes for equipment.

Vague Evaluation Plan

Medium

Funders want to know how you will measure success. Vague statements like we will track progress are not enough. You need specific metrics, timelines, and responsible parties.

Real Example:

We will evaluate the program effectiveness. vs. We will measure success through quarterly KPI reviews: 80% participant completion rate, 90% satisfaction score, and 3 published outputs by month 18.

How to Fix It:

Use SMART criteria: Specific, Measurable, Achievable, Relevant, Time-bound. Include both process and outcome metrics.

Ignoring the Review Criteria

Critical

Every solicitation includes explicit review criteria. Proposals that do not address each criterion directly are scored lower, regardless of their quality.

Real Example:

An NSF proposal scored poorly because it did not explicitly address Broader Impacts, even though the research was excellent.

How to Fix It:

Map each review criterion to a specific section in your proposal. Use the same language as the solicitation.

No Sustainability Plan

Medium

Funders want to know what happens after their money runs out. Proposals without a sustainability plan suggest the project will die when funding ends.

Real Example:

We plan to continue the research. vs. After grant completion, the platform will be sustained through institutional support ($120K/year) and a freemium SaaS model projected to generate $200K annually.

How to Fix It:

Include a specific sustainability section with multiple revenue streams: institutional support, follow-on grants, commercialization, or partnerships.

Submitting Without Review

High

Even experienced grant writers miss errors in their own work. Submitting without at least two rounds of review is the most preventable mistake.

Real Example:

A proposal referenced a previous grant number that had expired, immediately undermining credibility with reviewers.

How to Fix It:

Have a technical expert review the science and a grant specialist review the structure and compliance. Start reviews at least 2 weeks before the deadline.
