Cash Flow Forecasting: Techniques and Best Practices
Master cash flow forecasting for effective treasury management. Learn direct and indirect methods, rolling forecasts, variance analysis, and forecasting best practices.
Introduction: Know Your Cash Before It’s Gone
“We’re profitable but we can’t make payroll next week.”
This nightmare scenario happens more often than expected. Profitable companies fail because they run out of cash. Cash flow forecasting is the radar that helps treasury navigate through financial weather—good and bad.
Why Cash Flow Forecasting Matters
The Profitability Trap
Accounting Profit ≠ Cash:
- Revenue recognized ≠ Cash received
- Expenses recorded ≠ Cash paid
- Growth consumes cash
- Timing mismatches matter
Benefits of Good Forecasting
- Avoid cash crunch: Plan for shortfalls early
- Optimize returns: Invest surplus efficiently
- Reduce borrowing costs: Arrange funding ahead
- Support decision making: Inform business choices
- Manage banking relationships: Proactive communication
Types of Cash Flow Forecasts
By Time Horizon
| Type | Horizon | Purpose | Update Frequency |
|---|---|---|---|
| Daily | 1-14 days | Payment planning | Daily |
| Short-term | 2-13 weeks | Liquidity management | Weekly |
| Medium-term | 3-12 months | Funding planning | Monthly |
| Long-term | 1-5 years | Strategic planning | Quarterly |
By Method
1. Direct Method:
- Based on actual cash receipts and payments
- More accurate for short-term
- Requires detailed transaction data
2. Indirect Method:
- Starts with profit, adjusts for non-cash items
- Better for medium/long-term
- Uses financial statement projections
Direct Method Forecasting
The Approach
Track actual expected cash inflows and outflows.
Receipts Forecasting
Components:
- Customer collections
- Interest income
- Other receipts (asset sales, refunds)
Customer Collections:
$$Expected\ Collections = AR\ Balance \times Collection\ Rate$$
Example Collection Pattern:
| Days After Sale | Collection % |
|---|---|
| 0-30 days | 30% |
| 31-60 days | 50% |
| 61-90 days | 15% |
| 90+ days | 5% |
Forecasting Collections:
| Month | Sales | M+1 (30%) | M+2 (50%) | M+3 (15%) | M+4 (5%) |
|---|---|---|---|---|---|
| Jan | 100 | 30 | 50 | 15 | 5 |
| Feb | 120 | 36 | 60 | 18 | 6 |
| Mar | 90 | 27 | 45 | 13.5 | 4.5 |
Collections in April:
- Jan sales: 5 (M+4)
- Feb sales: 18 (M+3)
- Mar sales: 60 (M+2)
- Apr sales: 30 (M+1)
- Total: 113
Payments Forecasting
Categories:
| Type | Timing | Predictability |
|---|---|---|
| Salaries | Fixed dates | High |
| Rent/Utilities | Monthly | High |
| Supplier payments | Credit terms | Medium |
| Tax payments | Due dates | High |
| Loan repayments | EMI dates | High |
| Capex | Project based | Medium |
Supplier Payments:
$$Payments = Purchases \times (Payment\ Timeline)$$
Example:
- Purchases: ₹80 crore
- Payment terms: 45 days
- This month payment = Last month purchases
Daily Cash Flow Format
| Date | Opening | Receipts | Payments | Net | Closing |
|---|---|---|---|---|---|
| 1-Apr | 50.0 | 12.0 | (8.0) | 4.0 | 54.0 |
| 2-Apr | 54.0 | 8.0 | (15.0) | (7.0) | 47.0 |
| 3-Apr | 47.0 | 15.0 | (10.0) | 5.0 | 52.0 |
| … |
Indirect Method Forecasting
The Approach
Start with projected profit, adjust for:
- Non-cash items
- Working capital changes
- Financing activities
- Investing activities
Formula
$$Cash\ Flow = Net\ Income + Non{-}Cash + \Delta WC + Financing + Investing$$
Step-by-Step
Step 1: Start with Net Income From P&L forecast
Step 2: Add Back Non-Cash Items
- Depreciation
- Amortization
- Provisions
- Deferred taxes
Step 3: Adjust for Working Capital
- (Increase) in Receivables
- (Increase) in Inventory
- Increase in Payables
Step 4: Financing Activities
- New debt
- Debt repayment
- Equity issues
- Dividends
Step 5: Investing Activities
- Capital expenditure
- Asset sales
- Investments
Example Indirect Forecast
Monthly Cash Flow Forecast (₹ crore):
| Item | Apr | May | Jun |
|---|---|---|---|
| Net Income | 10 | 12 | 11 |
| + Depreciation | 5 | 5 | 5 |
| Operating Cash (pre-WC) | 15 | 17 | 16 |
| Δ Receivables | (8) | (5) | 3 |

| Net Cash Flow | 1 | 5 | 9 |
| Opening Cash | 30 | 31 | 36 |
| Closing Cash | 31 | 36 | 45 |
13-Week Cash Flow Forecast
Why 13 Weeks?
- Covers one quarter
- Provides visibility for major decisions

Scenario Planning
Why Scenarios Matter
Single-point forecasts are always wrong. Scenarios provide range.
Standard Scenarios
Base Case:
- Most likely outcome
- Normal business operations
- Primary planning scenario
Upside Case:
- Better than expected sales
- Faster collections
- Lower expenses
Downside Case:
- Sales decline
- Collection delays
- Cost increases
- Customer losses
Scenario Example
13-Week Cash Flow by Scenario (₹ crore):
| Scenario | Week 1 | Week 4 | Week 8 | Week 13 |
|---|---|---|---|---|
| Upside | 52 | 65 | 78 | 95 |
| Base | 50 | 55 | 60 | 65 |
| Downside | 48 | 40 | 32 | 20 |
Stress Testing
Key Questions:
- How long can we survive without new revenue?
- What if largest customer stops paying?
- What if credit lines are pulled?
Survival Analysis: $$Days\ Survived = \frac{Current\ Cash + Available\ Credit}{Daily\ Cash\ Burn}$$

Common Forecasting Mistakes
Mistake 1: Ignoring Seasonality
Problem: Assuming even cash flow throughout year Fix: Analyze historical patterns, adjust for seasonal factors
Mistake 2: Optimistic Bias
Problem: Forecasting best case as base case Fix: Use conservative assumptions, scenario planning
Mistake 3: Static Forecasts
Problem: Creating forecast once, not updating Fix: Rolling forecasts, weekly updates
Mistake 4: Missing Items
Problem: Forgetting tax payments, loan repayments Fix: Comprehensive checklist of all cash items
Mistake 5: Poor Communication
Problem: Business units don’t provide timely inputs Fix: Established process, accountability, executive support

Frequently Asked Questions
Q: How far out should we forecast? A: Daily for 1-2 weeks, weekly for 13 weeks, monthly for 12 months. Longer-term forecasts become less detailed but help strategic planning.
Q: What accuracy should we target? A: ±10% for near-term (1-4 weeks), ±20% for medium-term (13 weeks). Focus on directional accuracy more than precision for longer horizons.
Q: Direct or indirect method? A: Direct for operational forecasting (daily/weekly), indirect for strategic forecasting (monthly/annual). Many companies use both.
Q: How to handle uncertainty? A: Scenario planning is key. Also, build buffers into forecasts and maintain liquidity reserves for unexpected variances.
Q: Who should own the forecast? A: Treasury owns the process and consolidation, but business units own their inputs. Accuracy improves with cross-functional ownership.
Cash flow forecasting is like weather forecasting—you’ll never be exactly right, but good forecasting helps you prepare. Bring an umbrella when rain is forecast, arrange financing when cash deficit is forecast. The goal is to avoid surprises, not achieve perfection.
