Methodology

This guide is written to support a live calculator or decision flow already published on the site.
The content is structured for practical use: what the topic means, what affects the result, common mistakes, and what to check next.
Where the topic affects money, health, or compliance, the guide is intended as explanatory content before a final decision is verified against primary sources.

Decision checklist

Check	Why it matters
Confirm the current rule or document path	Practical guides are useful first, but official information should still control final decisions.
Separate concept from cost	A legal or compliance step often needs its own business or money analysis alongside it.
Keep a record of assumptions	It is easier to revisit the result when the source inputs and purpose are clear.

Best for Retirees, conservative savers, and anyone deciding between income and growth.

Monthly interest option

This option is useful when you want regular income. Many depositors choose it because it feels predictable and easy to budget around. It can suit retirees or households using FD income for monthly expenses.

Maturity value option

This option is usually better when the goal is to maximize what the deposit becomes by the end of the term. It is more suitable when you do not need the money every month and want a cleaner growth-oriented outcome.

Worked example

Suppose you have LKR 1,500,000. If you choose monthly interest, you receive regular payouts that can help with living expenses. If you choose the maturity option, you do not receive monthly cash, but the final amount may be more attractive for long-term savings goals.

How to choose the right one

Choose monthly interest if cash flow is the priority
Choose maturity value if long-term accumulation is the priority
Compare both outcomes using the same amount and tenure

Many depositors make the mistake of choosing the monthly-income version because it feels more visible. But if the money is not needed every month, the maturity-focused option may fit the goal better.
