A new finance library for javascript. Intended to improve the workflow of JavaScript developers who are also in the finance industry. The package includes nice helper functions to quickly get values for ratio analysis, time value of money, managerial calculations etc.
Currently version 1.x.x only has Time Value of Money
npm install businessjs
<script src="https://cdn.jsdelivr.net/npm/businessjs@1.2.1/build/index.min.js"></script>
This will give you the package available for use in any front-end or Node.js environment.
Import syntax:
import businessjs from 'businessjs';
In node environment:
const businessjs = require('businessjs');
const tvm = businessjs.tvm;
Using the CDN is recommended though.
<!DOCTYPE html>
<html>
<head>
<script src="node_modules/businessjs/build/index.js"></script>
</head>
<body></body>
</html>
This should create the instance globally on the window
<script>
const tvm = businessjs.tvm;
</script>
Methods
futureValue = function(presentValue, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.presentValue = function(futureValue, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.numPeriods = function(presentValue, futureValue, interest, [perPeriod = 1])perPeriod The amount of times an interest rate is compounded defaults to 1.interest = function(presentValue, futureValue, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.futureValueAnnuityDue = function(payment, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.futureValueAnnuityAdvance = function(payment, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.presentValueAnnuityDue = function(payment, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.presentValueAnnuityAdvance = function(payment, interest, [numPeriods = 1, perPeriod = 1])numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 1.effectiveRate = function(nominalRate, perPeriod)const tvm = require('businessjs').tvm;
// Convert the monthly nominal rate to yearly effective inline
tvm.futureValue(100, tvm.effectiveRate(0.1, 12), 1, 1);
amortisation = function(presentValue, interest, [numPeriods=1, perPeriod=12]){
period,
payment,
interestPortion,
principlePortion,
totalBalance,
principleBalance
}
numPeriods defaults to 1 as in 1 year.perPeriod The amount of times an interest rate is compounded defaults to 12 payments per year.These are just the first few methods in version 1, Documentation will be updated as version improves.
