Actually, I get \$38.0822 as the interest per day. Here's how:

200,000.00 in A2 6.95% in B2 =A2*B2/365 in B3, I get the above amount in cell B3.

Aloha, Ralph...

Interest for 15 days is 38.6111 per day

...What would the formula be to arrive at 38.6111 for 15 days?

???????????

Now, Tana Lee, look here:
Hello all,

Total loan amount is 200,000.00
Interest rate is 6.95%
Interest for 15 days is 38.6111 per day

My question is what would the formula be to arrive at 38.6111 for 15 days?

Thanks for any help
James
James's third line is "Interes for 15 days is 38.6111 per day".
James' fourth line is "...to arrive at 38.6111 for 15 days?"

I do think James is a little mixed up, but, "Interest for 20 years is STILL 38.6111 PER DAY", as long as the amount and % interest rate don't change.

if James means, "interes for 15 days", he should stop there, and the correct anser would be, 38.08219178*15 = \$571.2329 (he indicates four decimals, so, that's how I show it, even though only two decimals are ever used as a final figure).

7. Tana Lee / RalphA thanks for the help
It turns out Ralph clocked it.
200,000 x 6.95% = 13,900.00 / 360 = 38.61

Thanks again
James

8. ## Re: calculate interest per day

James,

See this thread regarding how financial institutions may define “daily interest”.

http://216.92.17.166/board2/viewtopic.php?t=51066

I’m pleased that you received an answer for your particular problem. However, applying that formula in another circumstance may not produce the expected result. In that situation, the financial institution may have adopted a particular definition of “daily interest”.

A 360 day year is referred to as "Bankers Rule" (12 x 30-day months). It is much easier for financial institutions to work interest calculations based on an even 30 day month, then to use actual days. The main point to note is that for any given nominal rate of interest, the effective rate of interest will be greater when a 360 day year is used in the interest calculation than when a 365 day year is used.

Regards,

Mike

9. ## Re: calculate interest per day

I might add that in the past two years, I have not found one bank (there may be, however) that doesn't use ACTUAL days, even 366 for a leap year, in doing their calculations.

So, yes, ALWAYS ask the particular banking institution to explain exactly how they calculate interest for your particular case.

Hi,
You can try this by naming the cells,
Total loan amount is 200,000.00 = p
Interest rate is 6.95% =R
Interest for 15 days =T

Try this and confirm
