Stepped bond rate calculator

[ronald coletto]

I am doing a bond calculation and I am having trouble calculating it

this is how it goes:

BOND RATES
$100,000.00 $25.00 $1,000.00
$400,000.00 $15.00 $1,000.00
$2,000,000.00 $10.00 $1,000.00
$2,500,000.00 $7.50 $1,000.00
$2,500,000.00 $7.00 $1,000.00
Over 7.5 $6.50 $1,000.00

example:
if the contract is
550,000.00

the 1st $100,000.00 = (100,000.00/1,000*25) = 2,500.00
the rest is $400,000.00 = (400,000.00/1,000*15) = 6,000.00
the remainder balance 50,000.00 = (50,000/1,000*10) = 500

for a total cost of the bond of (2,500+6,000+500)=9,000

thx in advance to someone that can help me with this, my tasks are over $10,000,000.00 and the change orders are changing the total price of the bond in construction so any help here is apreciated

Hi Ronald,

I am a bit confused by your post!

I am doing a bond calculation and I am having trouble calculating it

this is how it goes:

BOND RATES
$100,000.00 $25.00 $1,000.00
$400,000.00 $15.00 $1,000.00
$2,000,000.00 $10.00 $1,000.00
$2,500,000.00 $7.50 $1,000.00
$2,500,000.00 $7.00 $1,000.00
Over 7.5 $6.50 $1,000.00

example:
if the contract is
550,000.00

the 1st $100,000.00 = (100,000.00/1,000*25) = 2,500.00
the rest is $400,000.00 = (400,000.00/1,000*15) = 6,000.00
the remainder balance 50,000.00 = (50,000/1,000*10) = 500

for a total cost of the bond of (2,500+6,000+500)=9,000

The table looks wrong, the confusing stuff is red.

Also the Example looks wrong! I would expect the first $100K to be $2,500; the next $300k to be $4,500 and the last $150k to be $1,500 giving a total of $8,500.

If I am correct, then try this formula:

Note: It is only good up to $2 million - you'll need to edit it based on how the rate table should have appeared!

Hope this helps, please let me know!

$3,350,000.00 contract amount
$24,511.89 change order 1
$68,990.03 change order 2
$177,838.30 change order 3
AMOUNT with all change orders $3,621,340.22


1st 100k $100,000.00 $2,500.00
2nd 400k $400,000.00 $6,000.00
3rd 2 millions $2,000,000.00 $20,000.00
4th is the remainding balance of $3,621,340.22 $1,121,340.22 $8,410.05
total of the bond price $36,910.05
Hurricane 1.3% $479.83
Total $37,389.88



i posted my manual excel example for better understanding

Hi Ronald,

Believe it or not, your problem literally woke me up last night when it dawned on me that I was reading your table incorrectly! I made a quick note, and now here I am!

The formula is: =SUMPRODUCT(--(E16>{0,100000,500000,2500000,5000000,7500000}),--(E16-{0,100000,500000,2500000,5000000,7500000}),{0.025,-0.01,-0.005,-0.0025,-0.0005,-0.0005})

Here is your file where you can see it working. Bond Rate Calculator.xlsx

The SUMPRODUCT formula isn't linked to anything, but the blue values are where I worked out the values for the formula.

Sorry for the incomplete answer yesterday, I trust this one works for you!

Please test it and let me know!

Regards,

David
