Fund Reserve Allocation Calculator

Allocate an investable fund budget between initial checks and follow-on reserves.

01 / UNDERSTAND THE CONCEPT

Reserves compete with initial checks for the same budget.

An initial check and a follow-on reserve both consume finite fund capital. A reserve plan first deducts the expense budget from commitments and then divides the investable amount between initial deployment and later participation.

Equal per-company reserves are an average planning convention, not a claim that every company should receive the same support. The actual need depends on ownership, future round sizes, prices and the concentration policy.

02 / THE MATHEMATICS

The formula, made clear.

Investable budget = commitments − expenses; follow-on reserve = investable budget × reserve fraction
Reserve fraction
Applied to investable capital after the entered lifetime fee/expense budget.
Average initial check
Initial investment budget divided by target company count.
03 / A WORKED EXAMPLE

Put the numbers in context.

A $50,000,000.00 fund less $10,000,000.00 lifetime costs leaves $40,000,000.00 investable. A 50% reserve sets aside $20,000,000.00 and leaves $1,000,000.00 average initial checks across 20 companies.

MODEL BOUNDARIES

What this calculation assumes

A static commitment budget with no recycling, investment income, subscription facilities or changing fee schedule. The entered fee budget is not calculated from a management-fee rate.

FROM UNDERSTANDING TO ACTION

What to consider next.

Compare average reserves with the pro-rata cost of likely future rounds and test a concentrated follow-on policy.
