Direct vs. Indirect Cash Flow Forecasting: Understanding the Key Differences

Cash flow forecasting is a crucial element that can make or break any business, regardless of its size. At its simplest, cash flow forecasting is about monitoring the dollars that flow in and out of a business. But under the surface, it’s much more complex than that. Cash flow forecasting enables teams to strategically allocate resources to optimize their future. In 2025, treasuries are moving to faster, more connected forecasting—PwC finds leaders using real-time liquidity tools and AI-enhanced models to turn forecasts into decisions, while Hackett shows peer CCC improved to ~37 days in 2024, so targets should be peer- and trend-based, not static.

‍

In this blog post, we’ll discuss two primary methods of cash flow forecasting (direct and indirect) including the differences and advantages between them.

‍

What is Direct Cash Flow Forecasting?

Direct cash flow forecasting is a robust financial planning technique that involves using actual cash flow data as a foundation for future predictions. Picture it as a family setting a budget based on their past bank statements to anticipate upcoming expenditures. This method stands out for its reliance on tangible, real-world data, making it one of the most accurate tools in a company's financial arsenal. In practice, direct forecasting is most reliable out to ~13 weeks (weekly buckets), then precision drops—teams often roll to monthly thereafter.

‍

What is the Purpose of Direct Cash Flow Forecasting?

The idea behind direct cash flow forecasting is simple: it relies on historical data and current cash flows to predict future moves. This method provides a detailed snapshot of a company’s cash position, allowing for precise short-term planning.

‍

When Should I Use Direct Forecasting?

If your company needs to make decisions in the short term, direct forecasting is likely your friend (at least, if you have you have historical data to lean on). This makes it a go-to method for monthly or quarterly budgeting. Use the direct method for weekly liquidity (e.g., a rolling 13-week forecast required by lenders/boards) and short-term actions like collections campaigns and payment-run timing.

‍

How to Create a Direct Cash Flow Forecast

To create a direct cash flow forecast, follow these steps:

Start from bank & subledger data. Pull bank transactions, open AR (expected receipts), and AP/payroll/tax (expected disbursements).
Bucket weekly for 13 weeks. Place each receipt/disbursement in its expected week; create categories (customer receipts, card, ACH/wires; payables, payroll, taxes, debt service).
‍Add known events. Layer one-offs (capex, tax payments, debt draws/repayments, dividends).
Reconcile opening cash. Tie week 1 opening cash to bank-verified balances.
Roll forward. Ending cash = opening + receipts − disbursements each week; the next week’s opening equals the prior week’s ending.
Variance & accuracy. Each week, compare actuals vs. forecast; log drivers (e.g., slower collections) and tune assumptions.
Extend view. After week 13, roll to monthly (often via the indirect view) for planning.

‍

What is Indirect Cash Flow Forecasting?

Indirect cash flow forecasting for businesses is a method used to estimate future cash flows by starting with the company's income statement and making adjustments to arrive at the projected cash flows. Indirect shines for mid/long-term planning, scenario analysis, and aligning cash to the P&L/BS drivers (sales, margins, working capital).

‍

It is an alternative approach to forecasting cash flows when direct cash flow information is not readily available or when a company wants to project cash flows based on its profit and loss (P&L) statement, also known as the income statement. In this sense, it’s like a family estimating how future changes in income and expenses will impact their cash position and budget.

‍

What is the Purpose of Indirect Cash Flow Forecasting?

The purpose of indirect cash flow forecasting in business is to project and estimate future cash flows by starting with the income statement (profit and loss statement) and making adjustments for various non-cash items and changes in working capital. It provides a bridge between profitability and liquidity, helping businesses ensure they have the necessary funds to meet their obligations and pursue opportunities.This method is more suitable for mid- and long-term planning.

‍

When is Indirect Forecasting Suitable?

Indirect forecasting is for charting a business's course for the coming year or beyond. It's ideal for helping set goals and allocate resources accordingly. If a company is preparing for growth or expansion, indirect forecasting is its ally.

‍

How to Create an Indirect Cash Flow Forecast

To create an indirect cash flow forecast, follow these steps:

‍

Step 1: Gather Historical Financial Statements. Collect historical income statements, balance sheets, and cash flow statements for at least the past 12-24 months. This data will serve as a foundation for your forecast.

‍

Step 2: Define the Forecast Period. Determine the timeframe for your cash flow forecast. Common options are monthly, quarterly, or annually, depending on your business's needs and the level of detail required.

‍

Step 3: Start with the Income Statement. Begin with the company's historical or projected income statement. Identify the net income figure for each period within your forecast period.

‍

Step 4: Set driver assumptions. Define assumptions for sales growth, collections (DSO/collection curve), inventory turns (DIO), and payables terms (DPO); scenarios will flex these.

‍

Step 5: Adjust for Non-Cash Items. Identify and adjust for non-cash items that affect net income but do not impact cash flow.

‍

Step 6: Account for Changes in Working Capital. Analyze changes in working capital items, which include accounts receivable, accounts payable, and inventory. These changes can significantly affect cash flow. Calculate the change in each working capital item for each period in your forecast.

‍

Step 7: Factor in Capital Expenditures (CapEx). Include capital expenditures, which represent cash outflows for purchasing assets like equipment, machinery, or property. Estimate when these expenditures will occur within your forecast period.

‍

Step 8: Add Financing Activities. Consider financing activities that affect cash flow, such as:

Loan Proceeds: Include any loans or credit facilities that provide cash inflow.
Loan Repayments: Account for principal repayments, which are cash outflows.
Equity Issuances: Include any capital raised through equity issuances.

Step 9: Calculate the Change in Cash. For each period within your forecast, calculate the change in cash by adding or subtracting the adjustments made in steps 4, 5, 6, and 7 from the net income figure obtained in step 3. The result represents the net cash provided by (or used in) operating activities.

‍

Step 10: Determine Beginning and Ending Cash Balances. Start with the beginning cash balance for the first period in your forecast, which can be the actual cash balance from your historical data or an estimated starting point. Then, calculate the ending cash balance for each period by adding the change in cash calculated in step 8 to the beginning cash balance of that period.

‍

Step 11: Review and Revise. Regularly update and review your cash flow forecast as you progress through the forecast period. Compare actual results to your forecast, and adjust your model to reflect changes in business conditions, assumptions, or strategies.

‍

Use the indirect view to bridge to the direct 13-week model (near term direct; medium-term indirect), so executive dashboards reconcile both.

‍

Key Differences Between Direct and Indirect Forecasting

Direct and indirect cash flow forecasting differ in their methodologies and data sources. Teams choose between the two methods based on data availability, operational complexity, and their specific financial planning needs. Some businesses may use a combination of both methods for a comprehensive cash flow analysis.

‍

Data Sources and Availability

Direct forecasting relies on real cash flow data, making it accurate in the short term. However, it becomes less reliable as you move further into the future due to the scarcity of real data. Meanwhile indirect forecasting uses projected financial statements, which are useful for long-term planning. Many treasuries run a hybrid: direct weekly (13 weeks) for precision + indirect monthly/quarterly beyond for strategy.

‍

Level of Detail and Granularity

Direct forecasting provides a detailed view of a company’s cash position, helping with short-term tactical decisions. It makes it easy to see precisely when money will flow in and out. On the other hand, indirect forecasting offers a broader perspective, focusing on overall financial health and strategic planning. It may lack the precision needed for immediate tactical moves.

‍

Complexity

Direct forecasting requires access to real-time financial data and strong financial modeling skills, whereas indirect forecasting relies on financial statement analysis which makes it less accessible to businesses with limited resources.

‍

Accuracy and Reliability

Direct forecasting excels in the short term, offering high accuracy when there is access to historical data. However, it can lead companies astray when predicting cash flows years ahead. Indirect forecasting provides a reliable foundation for long-term planning. Its strength lies in forecasting cash flows over extended periods, allowing for better decision-making. For short-term accuracy, Gartner recommends direct with BU involvement; for longer horizons, indirect aligns cash to plan drivers.

How to Choose a Cash Flow Forecasting Method

When it comes to cash flow forecasting, businesses often face a critical decision: should they opt for a direct or indirect approach? To make an informed decision, consider the following factors:

‍

1. Identify Your Goals. Determine whether your company's primary focus is short-term precision or long-term strategy. If you need highly accurate, granular cash flow insights for day-to-day cash management, direct forecasting might be the way to go. On the other hand, if you're looking to chart a long-term financial strategy or communicate performance to stakeholders, indirect forecasting provides a broader perspective.

‍

2. Assess Data Availability. Evaluate the quality and quantity of historical financial data at your disposal. Direct cash flow forecasting relies on real-time cash transaction data, which may not be readily available in some cases. If you lack direct cash flow data, indirect forecasting based on financial statements can be a viable alternative.

‍

3. Consider Resources. Take into account your available resources, both in terms of data management and financial modeling capabilities. Direct forecasting can be data-intensive and may require sophisticated cash management systems. Indirect forecasting, based on financial statements, is often more accessible and doesn't demand the same level of data granularity.

‍

4. Define Time Horizons. Clearly define the timeframes for your financial planning efforts. Distinguish between short-term and long-term goals. Direct forecasting is well-suited for short-term precision, while indirect forecasting can provide strategic insights for long-term planning.

‍

5. Balance Precision and Strategy. Striking a balance between short-term direct forecasting and the strategic insights of long-term indirect forecasting can be advantageous. Businesses can use a combination of both methods to gain a comprehensive understanding of their cash flow dynamics, meeting immediate cash management needs while aligning with broader financial goals.

‍

In the end, the choice between direct and indirect cash flow forecasting should align with your business's unique circumstances and financial planning objectives. Whether you prioritize day-to-day cash management or long-term strategy, selecting the right approach will empower you to make informed financial decisions that drive success.

Which is Best For Your Business?

Cash flow forecasting isn't just about numbers; it's about steering a business toward success. In 2025, top teams combine direct + indirect and connect forecasts to action (collections, AP runs, funding)—a pattern seen in PwC 2025 and Strategic Treasurer 2025 survey work. By understanding the nuances of each option, finance professionals can chart a course that aligns with their company’s goals. The key is to make informed decisions that keep cash flowing into the necessary areas of a business.
