Fixed vs Fluctuating Capital Method: The Complete Guide for CBSE Class 12 Accountancy

Fixed vs Fluctuating Capital Method: The Complete Guide for CBSE Class 12 Accountancy

The difference between Fixed and Fluctuating Capital methods is one of the most frequently examined — and most frequently misunderstood — topics in Class 12 Accountancy. Once you understand the logic behind each method, the confusion disappears entirely.

Method 1: Fixed Capital Method

Under this method, each partner's Capital Account balance stays constant throughout the year. It changes only if:

• Fresh capital is introduced
• Capital is permanently withdrawn
• The profit-sharing ratio changes

All other adjustments are recorded in a separate Current Account.

What Goes Where

Format

Partner's Capital Account
─────────────────────────────────────────────────────
Dr                                              Cr
                          | Balance b/d  ₹X,XXX
                          | (remains constant)

Partner's Current Account
─────────────────────────────────────────────────────
Dr                              Cr
Drawings       ₹X,XXX | Interest on Capital  ₹X,XXX
Int. Drawings  ₹X,XXX | Salary               ₹X,XXX
Share of Loss  ₹X,XXX | Share of Profit      ₹X,XXX

When to Use It

• When the question mentions both a Capital Account and a Current Account for each partner
• More suitable for stable partnerships where partners prefer clarity about their original investment

Method 2: Fluctuating Capital Method

Under this method, all transactions are recorded in a single Capital Account per partner. There is no separate Current Account. The balance fluctuates — rises and falls — with every entry.

What Gets Recorded in the Capital Account

Format

Partner's Capital Account
─────────────────────────────────────────────────────
Dr                              Cr
Drawings       ₹X,XXX | Balance b/d          ₹X,XXX
Int. Drawings  ₹X,XXX | Interest on Capital  ₹X,XXX
Share of Loss  ₹X,XXX | Salary               ₹X,XXX
Balance c/d    ₹X,XXX | Share of Profit      ₹X,XXX

When to Use It

• When the question only mentions Capital Account (no Current Account)
• More common in practice; simpler to maintain
• Used when capital balances are expected to change regularly

Quick Identification Tricks for Exams

Fixed Capital — Spot It in 5 Seconds

The question uses both "Capital Account" and "Current Account" — or asks you to prepare both.

Fluctuating Capital — Spot It in 5 Seconds

Only "Capital Account" is mentioned, and the list of transactions includes profit share, drawings, interest, and salary — all going into one account.

Board Exam Tip

When preparing capital accounts in the exam:

• Label clearly — write "Capital Account" or "Current Account" as appropriate
• Show opening balance on the correct side (Cr for both, usually)
• Tick off each transaction as you enter it to avoid omissions
• Balance both sides and write "Balance c/d" to close

The examiner rewards neat, correctly labelled accounts — even partial marks for format are worth earning.
