Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Nonprofit Revenue Concentration to answer this question: measure revenue dependence on the largest funding source and the top three sources? Enter Total annual operating revenue, Largest funding source revenue, Second-largest source revenue, and 2 other inputs; the calculator shows Largest-source revenue concentration. Try changing one number and watch what happens to Largest-source revenue concentration. The answer tells you Largest-source revenue concentration.
Age 15Explain it to a 15-year-oldConnect it to the formula
Classify grants, contracts, gifts, fees and investment income consistently across periods. The rule is Funding concentration = selected source revenue ÷ total operating revenue. Its input values are Total annual operating revenue, Largest funding source revenue, Second-largest source revenue, Third-largest source revenue, Selected largest-source risk threshold (%), and the main result is Largest-source revenue concentration. Try changing one number and watch what happens to Largest-source revenue concentration.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Funding concentration = selected source revenue ÷ total operating revenue, evaluated from Total annual operating revenue, Largest funding source revenue, Second-largest source revenue, Third-largest source revenue, Selected largest-source risk threshold (%) to produce Largest-source revenue concentration. Classify grants, contracts, gifts, fees and investment income consistently across periods. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Measure revenue dependence on the largest funding source and the top three sources.
Why the business model works
Classify grants, contracts, gifts, fees and investment income consistently across periods.
Inputs and operating assumptions
This model uses Total annual operating revenue, Largest funding source revenue, Second-largest source revenue, Third-largest source revenue, Selected largest-source risk threshold. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Funding concentration = selected source revenue ÷ total operating revenue
What the calculator produces
The primary output is Largest-source revenue concentration; it also exposes Top-three revenue concentration, Amount above selected largest-source threshold. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
