How to Calculate Budget and Balance Automatically with Linked Tables
How to calculate budget balance automatically with linked tables instead of manual Excel formulas.
In Excel, budget balance usually lives in one cell while expenses sit on another sheet.
The formula references a range. Someone inserts a row in the wrong place — the calculation breaks, but the file opens without errors.
A Different Approach
In linked tables, each expense is tied to a project. Balance is a formula over related records:
Balance = Budget − SUM(expenses.amount)
Not a cell range B2:B47, but the sum of all expenses for that project. Add an expense — balance updates.
Example: Renovation Estimate
Project: apartment renovation. Budget: 20,000.
- Materials: 8,200;
- Works: 4,230.
Balance: 20,000 − 8,200 − 4,230 = 7,570.
The number appears on the project card. No separate "totals" sheet.
What If the Formula Is Wrong
In Excel, errors are often silent: the cell shows an old value or zero.
In a system with explicit formulas:
- you see which fields feed the calculation;
- configuration errors show up immediately;
- change history shows when and who changed budget or expense.
Fewer "magic" cells — more transparency.
