The calculator works as follows:

d.Identifying the External Funding Requirement
It is a very popular process taught across corporate finance courses, MBA programs, and financial analysts the world over.
Additional Funds Needed Formula
The standard AFN calculation formula is:
AFN=(ΔAssets)−(ΔSpontaneous Liabilities)−(Increase in Retained Earnings)
Expanded AFN Formula

Where:
- A/S = Assets-to-sales ratio
- L/S = Liabilities-to-sales ratio
- ΔS = Projected increase in sales
- PM = Profit margin
- S₁ = Projected sales
- RR = Retention ratio
This additional funds needed calculator projection formula is the foundation of all AFN financial calculators, spreadsheets, and Excel tools.
Step-by-Step Additional Funds Needed Example
A company plans to increase sales from $1,000,000 to $1,200,000.
| Financial Metric | Value |
|---|---|
| Assets/Sales Ratio | 0.60 |
| Liabilities/Sales Ratio | 0.20 |
| Profit Margin | 8% |
| Retention Ratio | 60% |
Step 1: Calculate Increase in Sales
ΔS=1,200,000−1,000,000=200,000
Step 2: Calculate Required Increase in Assets
ΔS=1,200,000−1,000,000=200,000
Step 3: Calculate Increase in Spontaneous Liabilities
ΔL=0.20×200,000=40,000
Step 4: Calculate Increase in Retained Earnings
RE=0.08×1,200,000×0.60=57,600
Step 5: Calculate Additional Funds Needed
AFN=120,000−40,000−57,600=22,400
Result
The business needs $22,400 in external funding to support growth.
This is exactly what an additional funds needed calculator spreadsheet, Excel AFN calculator, or online AFN tool computes instantly.
