30% Saving Rule and SIP Calculator: Targeting A ₹1.5 Crore Retirement Corpus

The 30% saving rule is a simple budgeting idea that links regular saving to long term goals such as retirement. A SIP calculator helps show how compounding can shape outcomes over time. 

How The 30% Saving Rule Connects to A SIP Calculator Example 

In this example, the 30% allocated to financial goals is assumed to go directly into a monthly SIP for retirement. This is only an illustration, since the same 30% can also include other priorities. 

Example Setup 

Mr A has a monthly after tax income of ₹50,000. 

• Monthly SIP Contribution: ₹15,000
• Investment Period: 20 Years
• Returns Assumed: 12% Annualised 

SIP Calculator Outcome For ₹15,000 Per Month Over 20 Years 

• Estimated Corpus After 20 Years: ₹1,49,87,219 which is close to ₹1.5 crore
• Total Invested Amount: ₹36,00,000
• Estimated Returns Component: ₹1,13,87,219 

These figures are purely mathematical outputs based on the inputs above. Changes in the assumed return rate, contribution amount, or time horizon can materially alter the final corpus. 

What These SIP Calculator Numbers Represent 

A SIP calculator projection typically splits the final value into two parts. 

• Invested Amount is the sum of all monthly contributions, which here is ₹15,000 multiplied by 240 months.
• Estimated Returns reflects the compounding effect over time using the assumed annualised rate. 

Since returns can vary over time, the calculation should be read as an illustration of how compounding works, rather than as a fixed outcome. 

What Is The 30% Saving Rule and the 30-30-30-10 Rule 

The 30% saving rule is often explained through the 30-30-30-10 rule, a budgeting framework that divides monthly after-tax income into four buckets. 

• 30% For Financial Goals such as savings, investments, and debt repayment
• 30% For Housing such as rent or home loan costs
• 30% For Essential Needs such as food, utilities, transport, and insurance
• 10% For Discretionary Wants such as dining out, hobbies, or entertainment 

This framework is meant to create discipline around financial goals while keeping spending balanced. The split can vary by lifestyle, city, and responsibilities, so it is best treated as a reference point.

Conclusion 

This example shows how a budgeting rule like the 30% saving rule can translate into a monthly SIP amount, and how a SIP calculator can be used to estimate the long term compounding outcome over a retirement time horizon.
