Most nonprofit organizations typically stop at simple budgeting and forecasting, which deprives them of valuable insights into their future financial outlook, including income and expenses.
If your organization uses spreadsheets and manual processes, you are limited to basic budgeting and forecasting.
Instead, you can use modern nonprofit financial management tools to augment other budgeting processes with comprehensive projections.
Today's guide examines various budget projection methods that enhance transparency, collaboration, and informed strategic decision-making. We'll also discuss the best tool for all your nonprofit budgeting needs.

A budget projection is a forward-looking financial tool that helps nonprofit organizations plan how they will use their resources in the future by modeling various potential outcomes.
While routine budgeting focuses on tracking current costs under various expense categories and staying within limits, budget projections look further ahead.
Your budget projection can look ahead in terms of months or years to estimate future income and costs based on shifting needs, objectives, and financing scenarios.
As a mission-driven organization, budget projections are important for responsible stewardship of funds, financial transparency, accountability to funders, and maximizing your organization's impact.
While they are related, budget, forecast, and projection play unique roles in your overall nonprofit financial management strategy.
Here's how they differ:
A budget is a spending plan that an organization usually creates at the beginning of its fiscal year based on expected income.
For example, you might budget to spend $10,000 on a youth program, assuming a certain level of grant funding or donations will be available.
A budget forecast is an updated spending estimate that considers your prevailing financial reality and adjusts your expectations to reflect that reality.
If you have six months remaining to the end of your fiscal year and you've only received three-quarters of the expected funds, a forecast can help revise your budget and guide real-time decisions.
For instance, you can delay a project or relocate funds.
A budget projection models different potential outcomes with “what-if” scenario analyses.
Let's say you are planning to launch a new community feeding program, but aren't sure how much funding you'll receive from grants. You can use projection to model several outcomes. What if we get full, partial, or no funding at all?
Why should your organization use all three?
When combined, budgets, forecasts, and projections help nonprofit leaders make more informed, flexible, and collaborative financial decisions.
Your budget provides the plan, forecasts keep the plan grounded in reality, and projections test different strategies for uncertainty or growth.
The combination helps your financial and non-financial teams to steward resources better, align your spending with the overall mission, and build trust with funders.

When you project your budgets, you are able to move beyond reactive financial management since you now have a clear, forward-looking view of where your organization is headed.
Projections save time, minimize errors, and promote faster, mission-aligned decisions. Here's how:

To enjoy these benefits, you can project your budgets in different ways to overcome the uncertainty that comes with fluctuating donations and unpredictable grant renewals.
Let's check out the three main types to consider.
You’ll want to combine these three types for a comprehensive view of your potential financial situations.

Each type of budget projection relies on several components or elements that ensure your financial outlook is accurate, transparent, and meaningful for all stakeholders.
Your projection should include the components below.
Capturing these elements doesn't have to be tricky.
You can use financial management tools with dashboards and custom reporting. Modern tools can visualize projections and keep all stakeholders aligned and confident in how you manage nonprofit finances.

Now that you understand what budget projection is and its key components, let's look at the various methods for building one.
Use past financial patterns to project future outcomes related to revenue and expenses. For example, if you have increasing donations in the second quarter, factor this into your year-end plans.
A rolling system updates your projections continuously throughout the year on a weekly, monthly, quarterly, or semi-annual basis. The idea is to reflect real-time changes in expenses, funding, or mission priorities.
You can build projections around key factors that affect your organization's income and expenses, such as volunteer hours and the number of events held. This approach shifts the focus from mere static numbers to projecting how your budget shifts when operations change.
This method projects revenue and costs around specific grant timelines, renewal likelihoods, and funding cycles. You can use it to plan for restricted vs. unrestricted grants and align expenditure with grant deliverables.
Nonprofits can project income based on best-case, moderate, and worst-case fundraising outcomes. It will be easier to plan around funding variability, campaign objectives, and economic changes in the market.
The zero-based system begins each budget cycle from zero, rather than rolling over the previous year's statistics. With this method, you can justify all expenses and align spending more tightly with mission priorities.
When applying these methods, you'll want to promote collaboration between financial and non-financial teams.
Collaborative budgeting helps break down spreadsheet silos, ensuring every participant contributes to and understands the projections beyond their own area of operations.
You'll also want to use modern software to leverage automation and real-time updates.
The key is to find a tool that can automatically import live data, minimise manual data entry, and update your projections as conditions change.

Speaking of software, let's check out the best and the key features to consider.
Spreadsheets are familiar, but they are vulnerable to control issues, siloed workflows, and costly errors. The best approach is to use a dedicated budget projection tool.
