Use XIRR for cash flows on different dates, such as SIPs or partial redemptions. CAGR suits a single beginning and ending value; the measures answer different questions.
Direct Answer
Use XIRR for cash flows on different dates, such as SIPs or partial redemptions. CAGR suits a single beginning and ending value; the measures answer different questions.
The page separates fixed logic from mutable inputs. A formula can be evergreen; a due date, rate, scheme rule, tax section, lender quote or market condition may not be. The official current source controls where a keyword contains a number or shorthand.
Why This Matters in 2026
Most planning errors are assumption errors rather than arithmetic errors. Inflation, expected return, college cost, retirement age, deposit rate and goal timing can move materially over a long horizon. The article therefore separates formula from assumption, shows a range instead of one forecast, and keeps tax/regulatory claims tied to current sources only where they actually affect the decision.
Use this order:
- Freeze the relevant date and category.
- Identify the exact source or product/scheme terms.
- Reconcile documents to inputs.
- Calculate the base case.
- Test the main exception and an adverse scenario.
- Preserve the evidence and next action.
Calculation / Legal Framework
XIRR solves Σ CFᵢ/(1+r)^((dateᵢ-date₀)/365)=0. Use actual dates, negative signs for investments and positive signs for withdrawals/current value.
Reproducible decision table
| Step | Control question | Evidence |
|---|---|---|
| 1. Period/date | Which FY/AY/tax year, contribution period, sanction date or valuation date applies? | Dated source + user record |
| 2. Scope | Does the rule/method cover this fact pattern? | Act/rule/scheme/product terms |
| 3. Inputs | Are amount, rate, date and classification reconciled? | Statement/invoice/contract/ledger |
| 4. Calculation | Can another reviewer reproduce the output? | Calculation sheet/export |
| 5. Exception | What fact would reverse the conclusion? | Proviso/exception/adverse case |
| 6. Action | What should be filed, paid, documented or monitored next? | Acknowledgement/decision note |
Worked Example
Invest ₹10,000 on 5 Jan, ₹10,000 on 11 Feb and ₹15,000 on 27 Mar; enter those as negative dated flows and year-end value as a positive flow. XIRR changes when dates change.
Numbers in the example are illustrative unless explicitly identified as an official current rate/threshold. Replace assumptions with the current notified/sanctioned/actual input before acting.
Practical Workflow
1. Classify the question before calculating
The search “mutual fund XIRR calculation SIP” can hide eligibility, calculation and execution questions. Separate them. An EMI does not establish affordability; a tax rate does not establish the correct return; a chart indicator does not establish a profitable trade.
2. Build a source-backed input sheet
For every input record value, unit, date and source. Label a rate as statutory, regulator-notified, contractual, market-derived or assumed. This makes future updates auditable.
3. Reconcile before filing or acting
Portal prefill, broker reports, lender illustrations and calculators are starting points. Reconcile them to books, statements, contracts, invoices, transaction history or scheme records. Investigate differences rather than forcing totals.
4. Stress-test
Ask what happens if the rate rises, return falls, cost increases, filing is late, liquidity disappears or a claimed credit/deduction is ineligible. Sensitivity often matters more than the base-case number.
5. Preserve evidence
Keep the official instrument/regulator page, calculation, source documents and filing/transaction acknowledgement. Keep the source date visible on evergreen pages.
Common Mistakes
- Using a keyword number as if it were an official current rate, limit or due date.
- Mixing regulatory/tax periods in one calculation.
- Quoting a calculator result without saving inputs and assumptions.
- Using a generic portal when an exact official rule/notification is available.
- Optimising a headline metric while ignoring cash flow, evidence and downside.
Documentation / Evidence Checklist
- Current official rule, notification, regulator FAQ or dated product/sanction terms.
- Calculation inputs with dates and units.
- Statements, invoices, payslips, tax statements, contract notes or bank/loan records relevant to the topic.
- Reconciliation of portal/broker/lender data to own records.
- Proof of filing/payment/transaction where applicable.
- A short decision note recording assumptions, exceptions and the analysis date.
