Challenge Scenario
In CRM account management and loyalty marketing, rewarding repeat enterprise clients requires measuring cumulative customer spend across multiple distinct transactions rather than evaluating each single invoice in isolation.
As a Key Account Manager, you are evaluating customer order histories:
- Cumulative Spend (Column C): Use
SUMIF to calculate the total lifetime spend for the customer named in Column A across the entire dataset ($A$2:$A$5).
- Account Tier (Column D): If the customer's cumulative spend exceeds $5,000, assign
"VIP", otherwise output "STANDARD".
- Portfolio Summary (B8 & C8): Count total orders and tally qualifying VIP orders.
Your Sheet Layout
Before entering your customer aggregation formulas, take a moment to understand the sheet architecture. Separating individual order transactions from cumulative lifetime spend metrics and executive tier totals ensures robust loyalty reporting.
The sheet is divided into three distinct operational zones:
- Order Ledger Zone (Columns A & B): Records customer names alongside the transaction amount ($) for each individual order.
- Customer Value & Tiering Zone (Columns C & D): Aggregates cumulative lifetime spend for each customer across the full dataset and assigns "VIP" status to customers spending over $5,000.
- Portfolio Loyalty Summary (Rows 7–8): Tallies total order volume and counts how many orders belong to qualified VIP accounts.

This layout ensures that repeat buyers are recognized across their full account history rather than assessed on single orders alone.
Complete the objectives below in the live spreadsheet editor. Each objective card will turn green once your formula evaluates successfully.
1
In Column C (C2:C5), sum cumulative customer spend using SUMIF($A$2:$A$5, A2, $B$2:$B$5).
2
In Column D (D2:D5), output "VIP" if Cumulative Spend > 5000, otherwise "STANDARD".
3
In cell B8, count total orders using COUNTA.
4
In cell C8, count "VIP" orders using COUNTIF.
Solution & Formula Breakdown
Evaluating multi-order customer spend requires conditional aggregation. Let's see how SUMIF and IF work together.
1. Aggregating Customer Lifetime Spend with SUMIF (C2:C5)
=SUMIF($A$2:$A$5, A2, $B$2:$B$5)
The SUMIF(range, criteria, sum_range) function calculates cumulative customer totals:
$A$2:$A$5: The locked customer names column to search through.A2: The specific customer to match on this row.$B$2:$B$5: The locked order amounts to sum up.- Acme Corp (Rows 2 & 4): Placed two orders ($3,200 + $2,500 = $5,700). Both rows output $5,700.
- Beta Inc (Row 3): Placed one order ($1,800). Output = $1,800.
- Delta Ltd (Row 5): Placed one order ($4,200). Output = $4,200.
2. Classifying Account Tiers (D2:D5)
=IF(C2 > 5000, "VIP", "STANDARD")
Because Acme Corp's cumulative spend ($5,700) exceeds $5,000, rows 2 and 4 receive "VIP" status. Rows 3 and 5 receive "STANDARD".
3. Portfolio Summary Metrics (B8 & C8)
- Cell B8 (Total Orders):
=COUNTA(A2:A5) → Evaluates to 4 orders.
- Cell C8 (Total VIP Orders):
=COUNTIF(D2:D5, "VIP") → Evaluates to 2 VIP orders.
Always lock both the search range ($A$2:$A$5) and the sum range ($B$2:$B$5) with dollar signs. Leaving them relative will shift the range down as you copy the formula, missing orders in earlier rows!
