Want running balance

Month 1:

Rent: $2,400 (Person A paid)
Electric: $120 (Person B paid)

Concert tickets ($160): Only 2 people
Restaurant ($80): Only 3 people

Calculator handles this:

Groceries: $200 ÷ 4 = $50 each (all)
Concert: $160 ÷ 2 = $80 each (Sam & Alex)
Restaurant: $80 ÷ 3 = $26.67 each (Jordan, Alex, Casey)

Final totals:
Sam: $50 + $80 = $130
Alex: $50 + $80 + $26.67 = $156.67
Jordan: $50 + $26.67 = $76.67

Common Bill Splitting Calculator Mistakes

Mistake 1: Forgetting Tax & Tip

Wrong:

Bill shows $100
Calculator: $100 ÷ 4 = $25 each

Right:

Bill subtotal: $100
+ Tax: $8
+ Tip $20
Total: $128
Calculator: $128 ÷ 4 = $32 each

Mistake 2: Not Including Everyone

Wrong:

3 people at dinner, 1 didn't order
Split bill 3 ways
Unfair to person who didn't order

Right:

Use **split bill calculator** to assign costs:
- Person A: Entree + drink = $35
- Person B: Entree + drink + appetizer = $45
- Person C: Entree only = $28
- Person D (didn't eat): $0
+ Shared tax/tip split 3 ways

Mistake 3: Duplicate Entries

Wrong:

Mar 5: Groceries - $80 (added by Alex)
Mar 5: Groceries - $80 (added by Bailey)
Calculator shows: $160 grocery spend

Right:

One person logs each expense
Or: Check in group before adding
Or: Use calculator with duplicate detection

Mistake 4: Wrong Number of People

Wrong:

Restaurant bill: $150
Calculator: $150 ÷ 5 people = $30 each
But actually only 4 people!
Each actually owes: $37.50

Right:

Count everyone present
Update calculator count
Even better: Named people in calculator

Mistake 5: Not Settling Regularly

Wrong:

Use **splitting costs calculator** for 6 months
Never settle up
Final balance: Someone owes $842.67
"I don't even remember what this is from..."

Right:

Monthly settlements
Clear the balance
Start fresh each month
Avoid large accumulated debts
