how to convert this excel formula into rollbase
Payment=(B4/b5,b3*b5,-b2)
{!Loan_Amount#value} =b2
{!Interest#value} =b4
{!Months}=b3
And what this formula does?
the real formula in excel is =PMT(B4/B5,B3*B11)
The values from
B2 = 200000
B3 = 30
B4 = 6.75%
B5 =12
Result is $1297.20
Hi robie I have this formula caliculated in Excel but I would like to transfer that formula in Rollbase Please help on this
I need to convert that excel formula in Rollbase formula
Unfortunately we don't have PMT as built-in function.
so how can we convert that PMT and rest of the formula
so is there a way to cut that formula into different parts and finally making up the result
Please check this out for PMT implementation in JavaScript:
cant we have a better split directly using the fields functions internally and adding them
robie can you give me a sample how can I implement the same sample javascript code in rollbase plz
Hi misteryminds,
Following provobie example : http://stackoverflow.com/questions/2094967/excel-pmt-function-in-js
Try this:
function PMT(i, n, p) {
return i * p * Math.pow((1 i), n) / (1 - Math.pow((1 i), n));
}
return PMT({!Interest#value}, {!Months}, {!Loan_Amount#value});
PS: it is just an example. Your formula might contain a different business logic.

Ricardo I tried this as such... but on validation itself its failing bad :(
What is the error message?
I need more details...
There were a couple plus signs missing and the return in front of the function fails.
Try this and replace the values in the function call with your tokens:
function pmt(rate_per_period, number_of_payments, present_value, future_value, type){
if(rate_per_period != 0.0){
// Interest rate exists
var q = Math.pow(1 + rate_per_period, number_of_payments);
return -(rate_per_period * (future_value + (q * present_value))) / ((-1 + q) * (1 + rate_per_period * (type)));
} else if(number_of_payments != 0.0){
// No interest rate, but number of payments exists
return -(future_value + present_value) / number_of_payments;
}
return 0;
}
pmt(0.0675/12,12*30, 200000, 0, 0);
well to make it more simpler I tried something simpler than everything
var loan_amount = {!total_loan_amount};
var interest_rate = {!interest_rate};
var loan_term = parseInt({!loan_term#value});
var rate = interest_rate/(100*12);
var r = rate + 1;
var calc = 1-(Math.pow(r, -(loan_term)));
var payment = (rate/calc)*loan_amount;
payment = payment.toFixed(2);
if (payment == "Infinity" || payment == "NaN") return "Cannot be computed because Loan Term is null."
else return "$"+payment ;
