| 610713 | 2007-11-11 23:11:00 | Lets say I deposited $250 in a long term savings account, with the interest compounded (added to the principal) each year, for 20 years (starting in 1987). What would it be worth now, if the bank is here in New Zealand? Currently long term deposits get about 8%. Where can I find what interest banks offered over the last 20 years? I found this site to calculate compound interest: math.about.com In the 1980's I think interest was higher than what it is now, up to 12% or more, but maybe my memory is wrong. My guess is that on average, the annual interest that banks and other savings institutions have offered would be around 7% - 8%. Any ideas? |

| 610716 | 2007-11-12 23:15:00 | Frequently the interest paid is proportional to the amount deposited - somehow I doubt whether you would receive top rates on $250.00. A sore point about the calculation of tax on the interest on savings accounts is that the cost of the account fees is not taken into account in calculating the tax payable. As the Account fees are part and parcel of the contract between the Bank and it's customer, it could be said that they are an earnings related cost and should be tax deductible. hence with accounts with balances below $1000, frequently the Account Fees exceed the net interest after tax. |

| 610718 | 2007-11-13 19:12:00 | The Reserve Bank has a table showing bank deposit rates going back to 1965. www.rbnz.govt.nz Table B3 Historical Series. | Mercury (1316) | ||
| 610719 | 2007-11-13 19:30:00 | One fun thing on the Reserve Bank site is their CPI Inflation calculator (www.rbnz.govt.nz). That $250 in 1987 is equivalent to $441.74 in today's money. |

| 610720 | 2007-11-13 23:24:00 | Probably the account would have been closed when it reached $0.00, because the bank has been charging a "fee" every month. | Graham L (2) | ||
