Data Validation & Audit
Prevent Split Allocations from Exceeding Total Pool or 100% Cap
Audit equity splits, cost-center allocations, and grant distributions so SUM($B$2:$B$6) never exceeds the master pool $E$2, reporting exact unallocated headroom or over-allocation excess.
Keeping cap-table percentages and grant sub-awards strictly within the 100% or dollar ceiling!
Whenever analysts split a fixed $250,000 grant pool or 100% ownership table across multiple recipients, editing a single row can quietly push the column total to 102.5% or $258,000! Locking the range reference inside SUM($B$2:$B$6) <= $E$2 (the exact formula used in Excel Custom Data Validation -> "Don’t exceed total") catches over-allocations the instant they happen!
Pair that ceiling test with a signed headroom indicator $E$2 - SUM($B$2:$B$6) and a three-state status formula ("Fully Allocated" when Pool = Sum, "Unallocated Remainder" when Sum < Pool, and "Over-Allocated — Exceeds Pool!" when Sum > Pool)!
| Grant Pool ($250,000) vs Line Sum | Remaining Headroom ($E$2 - SUM) | Allocation Status |
|---|---|---|
| Allocated Sum = $235,000 | +$15,000 Remaining | "Under Cap ($15,000 Unallocated)" |
| Allocated Sum = $250,000 | $0 Remaining | "Fully Allocated (Exact Match)" |
| Allocated Sum = $262,000 | -$12,000 Deficit | "Over-Allocated — Exceeds Pool!" |
Three-State Pool Allocation Audit (Under Cap / Fully Allocated / Over-Allocated)
Compares total line allocations SUM(B2:B5) against master pool ceiling E2 and guard against negative entries with MIN(B2:B5) < 0.
=IF(OR(E2 <= 0, MIN(B2:B5) < 0), "Invalid Pool or Negative Split", IF(SUM(B2:B5) > E2, "Over-Allocated — Exceeds Pool!", IF(SUM(B2:B5) = E2, "Fully Allocated (Exact Match)", "Under Cap — Remainder Available")))Remaining Unallocated Pool Balance ($E$2 - SUM)
Returns positive remaining capacity when under cap, 0 when fully allocated, or negative overrun when exceeded.
