# Free Financial Calculators Online

See below for a list of our ever-growing number financial calculators. Don’t see the calculator you need? Feel free to suggest one to us by reaching out here or on social media. Even though all our calculators are free, we’re always looking for ways to improve the site. Additionally, it’s important to note that these calculators may be missing variables relevant to you or your purchase decision. Personally, I’ve found it’s best to start with a simple calculation to get close before getting lost in the minutiae of financial calculations.

**Liquidity Ratio Calculator Online**

Our Liquidity Ratio Calculator is designed to compute a variety of liquidity ratios and working capital. Here’s a brief explanation of each:

**Current Ratio**: The current ratio is a liquidity ratio that measures a company’s ability to pay off its current liabilities (debts due within one year) with its current assets (cash, inventory, receivables, etc.). The formula used is`Current Assets / Current Liabilities`

.**Quick Ratio**: Also known as the “acid-test” ratio, the quick ratio is another measure of a company’s short-term liquidity. It excludes inventory from current assets before comparing to current liabilities because inventory may not be easily convertible to cash. The formula used is`(Current Assets - Inventory) / Current Liabilities`

.**Cash Ratio**: The cash ratio is a much more stringent measure of a company’s liquidity, considering only cash and cash equivalents (assets that can be immediately converted into cash) against the current liabilities. The formula used is`(Cash + Cash Equivalents) / Current Liabilities`

.**Working Capital**: Working capital is a measure of a company’s operational liquidity and short-term financial health. It’s calculated by subtracting current liabilities from current assets. Positive working capital indicates that a company has enough assets to cover its short-term debts. The formula used is`Current Assets - Current Liabilities`

.

This financial calculator can be incredibly useful for financial analysts, investors, creditors, and business owners who want to assess a company’s short-term financial health. For instance, before investing in or extending credit to a company, one might want to evaluate these liquidity ratios to assess the company’s ability to meet short-term obligations. Similarly, business owners can use this tool to keep track of their financial stability and make informed decisions about managing their assets and liabilities.

**Loan Calculator**

This calculator is a Loan Calculator that calculates monthly payment, total interest paid over the loan term, and displays an amortization schedule for a loan. Here’s what you can do with this calculator:

**Monthly Payment**: The monthly payment is the amount that the borrower is required to pay each month until the loan is paid off. It’s calculated using the loan amount, annual interest rate, and the term of the loan in years. The formula used in your code is`(loanAmount * interestRate) / (1 - Math.pow(1 + interestRate, -loanTerm))`

, which is a standard formula for calculating fixed monthly payments on an amortizing loan.**Total Interest**: This is the total amount of interest the borrower will pay over the term of the loan. It’s calculated by multiplying the monthly payment by the total number of payments (loan term in months) and then subtracting the initial loan amount.**Amortization Schedule**: An amortization schedule is a complete table of periodic loan payments, showing the amount of principal and the amount of interest that comprise each payment until the loan is paid off at the end of its term. The script generates this by repeatedly calculating the interest and principal amounts for each period and reducing the balance accordingly.

**Simple Interest Calculator**

This calculator is a Simple Interest Calculator. It’s designed to calculate the total amount (Principal + Interest) after a certain period of time given a specific interest rate and initial principal amount.

The Simple Interest formula used here is `Principal * (1 + Rate * Time)`

. This formula calculates the accumulated amount, which includes both the initial principal and the interest earned.

“Principal” refers to the initial sum of money that is borrowed or invested, before interest. “Rate” is the annual interest rate (in decimal form, i.e., 5% would be entered as 0.05). “Time” is the length of time the money is borrowed or invested for, measured in years.

This calculator is particularly useful for anyone who wants to quickly understand how their investment or loan might grow over time with a given interest rate. It can be used by investors to project future earnings, by borrowers to understand potential loan costs, or by anyone who simply wants to understand the concept of simple interest.

However, it’s worth noting, as the name would seem to imply, that this calculator assumes simple interest, which is calculated only on the initial principal. In reality, many loans and investments compound interest over time, meaning interest is calculated on both the initial principal and also on accumulated interest from previous periods. Therefore, this calculator is best used for illustrative purposes or for calculations involving simple interest specifically.

**Time Value Money Calculator**

It wouldn’t be a real website with financial calculators if we didn’t have a Time Value Money Calculator. The Time Value of Money is a fundamental financial principle that describes the concept of money available at the present time is worth more than the same amount in the future due to its potential earning capacity. In other words, a dollar today is worth more than a dollar tomorrow.

The calculator uses the general TVM formula `PV*(1+Rate)^n + PMT*((1+Rate)^n - 1)/Rate - FV`

to calculate the time value of money based on five parameters:

**Present Value (PV)**: This is the current worth of a future sum of money or stream of cash flows given a specified rate of return.**Future Value (FV)**: This is the value of an asset or cash at a specific date in the future that is equivalent in value to a specified sum today.**Interest Rate (Annual)**: This is the annual rate of return or interest on an investment.**Number of Periods (n)**: This is the number of time periods the money is invested or borrowed for.**Payment (PMT)**: This is the payment made each period; it cannot change over the life of the investment or loan.

The time value of money calculator can be used in personal finance, business finance, and investment to calculate the value of investments or loans.

Some ways you might use our TVM Calculator include:

**Investment analysis**: Investors can use this calculator to evaluate the profitability of investments and compare the value of future cash flows to the present value.**Loan repayment**: Borrowers can use this calculator to understand their loan repayment schedule and find out how much they’ll owe in the future.**Retirement planning**: Individuals can use this calculator to determine how much they need to save each month to reach their retirement goal.

Remember, this calculator assumes that the interest rate is constant over the life of the investment or loan, which may not always be the case in real-world scenarios.

**Compound Interest Calculator**

Compound interest is the interest on a loan or deposit that is calculated based on both the initial principal and the accumulated interest from previous periods. It is considered one of the most effective ways to build wealth over time.

The compound interest calculator uses the formula `Interest = P * ((1 + (r / 100))^t) - P`

to calculate the compound interest based on three parameters:

**Principal Amount**: This is the initial amount of the loan or deposit.**Annual Interest Rate (%)**: This is the annual interest rate. It’s important to note that the rate should be inputted as a percentage, not a decimal. For instance, an interest rate of 5% should be inputted as 5, not 0.05.**Time (in years)**: This is the number of years the money is invested or borrowed for.

Use cases:

**Savings**: If you have money in a savings account that earns compound interest, you can use this calculator to predict how your savings will grow over time.**Investment**: If you are considering an investment that compounds interest, such as a certificate of deposit or a bond, you can use this calculator to compare the potential returns of different investment options.**Loan Repayment**: If you have a loan that compounds interest, you can use this calculator to understand how much interest you will end up paying over the life of the loan.

We hope this calculator will be especially useful to anyone looking to make informed decisions about saving, investing, or borrowing. However, it assumes the interest rate is constant over the life of the investment or loan, which may (or may not) be the case in real-world scenarios.

**Car Loan Calculator**

Need hep planning your car loan? Try our Car Loan Calculator. It is designed to help you estimate your monthly payments for an auto loan based on the principal loan amount, annual interest rate, and loan term in months.

The formula used in the calculator to compute the monthly payment is `(Loan Amount * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^-Loan Term)`

. It also computes the total interest paid over the course of the loan using the formula `Monthly Payment * Loan Term - Loan Amount`

.

Use Cases:

**Vehicle Purchase Planning**: If you are planning to purchase a vehicle and are considering financing options, this calculator can help you estimate your monthly payment, total interest paid over the life of the loan, and develop a repayment schedule (also known as an amortization schedule), which will show you how each payment is divided into principal and interest.**Financial Budgeting**: This calculator is also beneficial for budgeting. By understanding the monthly payment, you can see how the loan will fit into your monthly budget. You can adjust the loan amount, term or rate to see how these changes affect your monthly payment.**Loan Comparison**: If you have been offered loans with different terms or rates, you can use this calculator to help compare these options side by side.

The calculator also creates an amortization schedule, providing a detailed view of how the loan will be paid off over time. It shows the amount of principal and the amount of interest comprised in each payment, and how the balance decreases over time.

**Effective Interest Rate Calculator Online**

Our Effective Interest Rate Calculator is another user-friendly financial tool designed to help you compute the real annual rate of interest, considering the effect of compounding. This tool operates on the principle that the nominal rate, or the base interest rate stated in your contract or agreement, often doesn’t reflect the true cost or return on a loan or investment. The actual annual return or cost, often termed as the effective interest rate, is usually higher due to the phenomenon of compounding, where interest is added to the principal balance more frequently than annually. This calculator requires two inputs – the nominal interest rate and the number of compounding periods per year, and then utilizes these to calculate the effective interest rate.

The formula used by the calculator is derived from the mathematical concept of compound interest, and is algebraically expressed as `r = (1+i/n)^n - 1`

. In this formula, `r`

stands for the effective annual rate, `i`

is the nominal rate, and `n`

represents the number of compounding periods per year. When the formula is applied, it calculates the effective annual rate, which provides a more accurate measure of actual interest, giving you a clearer financial picture whether you’re investing or borrowing.

**Life Insurance Estimator Tool**

This tool is a Life Insurance Coverage Estimator. It’s precisely designed to calculate the recommended coverage amount you would need based on key personal and financial information. It employs a formula that considers various factors such as age, income, debts, and the number of dependents to suggest an appropriate level of life insurance.

The formula used by our Life Insurance Coverage Estimator is: `Recommended Coverage = (Income x Years of Support) + Debts + (Education Fund per Dependent x Number of Dependents) - Existing Coverage`

. “Income” represents the annual earnings that need replacement, “Years of Support” is the number of years the income should be replaced, “Debts” include any outstanding obligations, and “Education Fund per Dependent” is an estimated cost of education for each dependent. “Existing Coverage” accounts for any current life insurance policies already in place.

Our estimator is invaluable for anyone who wants to ensure their loved ones are financially secure in the event of their untimely passing. It’s tailored for individuals looking for a straightforward way to assess their insurance needs, from parents and spouses to business owners and single adults. While our calculator simplifies the process, we recommend consulting with a financial advisor for a comprehensive analysis, as life insurance needs can be complex and may require a more nuanced approach.
