Online compound interest calculators?

[b0und]

Ok, I am looking for an online compound interest calculator that is a bit more sophisticated, allowing you weekly, monthly or quarterly additions, the best I could find was this one:

But it only allows annual additions.

Anyone know a better/more detailed one?

Use Excel:

FV(rate,#per,[pmt],[pv],[type])

* rate is the interest rate per period. In our example, rate is 0.08.

* #per is the number of periods in the future at which you want to compute the future value. #per is also the number of periods during which the annuity payment is received. In our case, #per equals 40.

* pmt is the payment made each period. In this example, pmt is -$2,000. The negative sign indicates we are receiving money.

* pv is the amount of money (in today’s dollars) owed right now. In our case, pv equals $0. If we owed someone $10,000 today, pv would equal $10,000. If we had $10,000 in the bank today, pv would equal -$10,000. If pv is omitted, it's assumed to equal zero.

* type is 0 or 1, and it indicates when payments are due or money is deposited. If type equals 0 or is omitted, money is deposited at the end of a period. In our example, type is 0 or omitted. If type equals 1, payments are made or money is deposited at the beginning of a period.

Let me know if you can't figure that out bud.
