Frequently asked questions
Savings account or fixed deposit?
A savings account gives easy access but a lower rate. A fixed deposit locks funds for a set period at a higher rate. Many people use both.
How often does interest compound?
Most Sri Lankan savings accounts calculate interest daily and credit it monthly. This calculator assumes monthly compounding.
Should I save or invest?
Emergency savings and short-term goals belong in a savings account. Long-term goals (5+ years) usually deliver better after-inflation returns from diversified investments.
Are savings account balances safe?
Deposits in licensed Sri Lankan banks are protected under the Sri Lanka Deposit Insurance Scheme up to specified limits per depositor per bank.
