Is Bank Fixed Deposits Closure and Renewal profitable?

As investment planning exercise, we quite often review our Fixed Deposits especially there is a bank interest rate changes. Usually when the interest rate changes upward by 1-2 % we close the existing FD which had run for certain periods and renew the same investment at the revised existing.   In such scenario it is better to verify whether the deal is profitable as some banks may impose 1% penalty and the period elapsed may have lesser interest rate than the original deposit rate.

A simple online calculator to verify fixed deposit renewal and closure scenario using different interest rates one for current interest rate,  future interest rate and interest rate provided for the period already elapsed till now.

Systematic Investment Planning – SIP – Calculators

We started off with a design of simple calculator for knowing a monthly SIP amount that we may have to save in terms of our financial planning to achieve any financial goal. Then I thought of designing online interactive multipurpose SIP calculator for different life goals from financial planning perspective   After trial and error Zoho sheet was found apt for the job which you may view here .

Three goals viz

  1. child’s education expenses in future
    • You need to input the current age, year (age) when higher education begins and estimate of expenses at current levels.
  2. child’s marriage expenses in future
    • You need to input the current age, year (age) when marriage is expected and estimate of expenses at current levels


  3. retirement corpus needed at the time of retirement can be estimated using the same calculator. 
    • You need to input the current age, year (age) when you expect to retire and an estimate of current monthly expenditure for maintaining the life-style preferred.

For all the goals you may have to indicate inflation rate (say 3% to 10%) and investment rate of  interest (say 3% to 20%)

It is sane to expect 8-9% from short term funds, 12% returns from long term debt funds and 14-18% in equity oriented mutual funds.


Once these goals are estimated then it is easy to calculate the monthly saving required in the form of SIP investment amount.  A sheet has been added to the cash flows involved in the calculation.
