Rounding in Accounting
Rounding in accounting is an important principle that concerns how numbers should be presented and treated in accounting . Correct rounding ensures consistency, clarity and compliance with accounting rules.
What is Rounding in Accounting?
Rounding in accounting refers to the process of simplifying numbers by reducing the number of decimal places or removing less significant digits. This is done to:
- Improve readability of financial statements
- Ensure consistency in presentation
- Follow accounting rules and standards
- Reduce complexity in accounting reports
Rounding affects both the balance sheet and the income statement, and must be done systematically and consistently.
Accounting Rules for Rounding
Norwegian Accounting Standards
In Norway, rounding in accounting follows specific rules:
Accounting Act Section 7-1
- Amounts must be stated in whole kroner or in thousands of kroner.
- Consistent rounding throughout the entire accounting
- Clear indication of rounding level
Rounding levels
| Company type | Recommended Rounding Level | Example |
|---|---|---|
| Small businesses | Whole crowns | 1,234,567 kr |
| Medium-sized enterprises | One thousand kroner | 1,235 thousand kroner |
| Large enterprises | One thousand kroner | 1,235 thousand kroner |
| Group | One thousand/million kroner | 1.2 million NOK |
Rounding methods
Mathematical Rounding (Most Common)
Mathematical rounding follows standard mathematical rules:
- 0.1-0.4: Round down
- 0.5-0.9: Round up
Examples of Mathematical Rounding
| Original amount | Rounded to whole kroner | Rounded to the nearest thousand kroner |
|---|---|---|
| 1,234.3 kr | 1,234 kr | 1 thousand kroner |
| 1,234.5 kr | 1,235 kr | 1 thousand kroner |
| 1,234.7 kr | 1,235 kr | 1 thousand kroner |
| 1,567.8 kr | 1,568 kr | 2 thousand kroner |
Bankers Rounding
Banker's rounding (also called "round half to even"):
- At 0.5: Round to the nearest even number
- Reduces systematic bias in large data sets
- Rarely used in Norwegian accounting
Practical Implementation of Rounding
Consistency in Accounting
Same Rounding Level
- All records must use the same rounding level
- Balance must be correct after rounding.
- Checking rounding differences
Rounding differences
When rounding creates differences:
- Small differences: Adjusted against equity
- Major differences: Requires closer analysis
- Documentation: All adjustments must be documented.
Accounting for Rounding Adjustments
Eksempel på avrundingsjustering:
Før avrunding:
- Omsetning: 1 234 567,80 kr
- Kostnader: 987 654,30 kr
- Resultat: 246 913,50 kr
Etter avrunding til tusen kroner:
- Omsetning: 1 235 tkr
- Kostnader: 988 tkr
- Resultat: 247 tkr
Avrundingsjustering: 0,50 kr til egenkapital
Tax Consequences
The Tax Administration and Rounding
Tax return
- The Tax Administration requires a statement in full kroner.
- Rounding to the nearest krone is required.
- Consistency between accounting and tax return
VAT and Rounding
- VAT returns must be stated in whole kroner.
- Rounding each line before summing
- Special rules for VAT compensation
Audit implications
The Auditor's Responsibility
- Checking rounding principles
- Ensure consistency in application
- Assess the materiality of rounding differences
| Materiality threshold | Action |
|---|---|
| Less than 0.5% of turnover | Acceptable |
| 0.5-1% of turnover | Closer assessment |
| Over 1% of turnover | Requires adjustment |
Digital Accounting Systems and Rounding
Automatic Rounding
Modern accounting systems handle rounding automatically:
System settings
- Rounding level can be set globally
- Automatic adjustments for differences
- Report generation with consistent rounding
Control routines
- Balance check after rounding
- Difference reports for follow-up
- Historical tracking of rounding adjustments
Best Practices for Digital Systems
- Set rounding rules early in implementation
- Test rounding logic thoroughly
- Document rounding principles in system documentation
- Train users in rounding handling
International Perspectives
IFRS and Rounding
International Financial Reporting Standards (IFRS) have their own guidelines:
IAS 1 - Presentation of Financial Statements
- Materiality shall be assessed by rounding.
- Consistent presentation required
- Clear indication of rounding level
Comparison with Norwegian Rules
| Aspect | Norwegian rules | IFRS |
|---|---|---|
| Rounding level | Whole kroner/thousand | Flexible |
| Consistency | Required | Required |
| Documentation | Detailed | Principle-based |
Practical Examples and Cases
Case 1: Small Business with Simple Structure
Background: Sole proprietorship with turnover of NOK 850,000
Rounding strategy:
- Whole kroner in all accounting lines
- Monthly check of rounding differences
- Simple documentation of rounding principles
Result:
- Consistent presentation throughout the year
- Minimal rounding differences (under 50 kr in total)
- Easy auditing and approval
Case 2: Medium-sized Company with Complex Structure
Background: AS with turnover of 25 million NOK and several subsidiaries
Challenges:
- Consolidation of accounts
- Currency conversion and rounding
- Group eliminations with rounding effects
Solution:
- One thousand kroner as standard rounding level
- Centralized rounding control
- Automated control routines
Common Mistakes and Pitfalls
Typical Rounding Errors

- Problem: Different rounding levels in the same financial statements
- Consequence: The balance is not right
- Solution: Standardize rounding principles
Lack of Control of Differences
- Problem: Rounding differences not identified
- Consequence: Error in accounting
- Solution: Implement control routines
Wrong Rounding Method
- Problem: Using incorrect rounding rules
- Consequence: Systematic errors
- Solution: Training and documentation
Preventive Measures
