Basic Arithmetic Formulas

Okay, let's start with the basics. These are the formulas you'll use all the time, so it's essential to get comfortable with them. We're talking about addition, subtraction, multiplication, and division. These are the bread and butter of financial calculations.

Addition

The addition formula in Google Sheets is super straightforward. You use the SUM function to add up numbers. For instance, if you want to add the values in cells A1 and A2, you'd use the formula =SUM(A1, A2). You can also add a range of cells. If you want to add up all the values from A1 to A10, you'd use =SUM(A1:A10). It's as simple as that!

Let's say you're tracking your monthly income and expenses. You might have your income sources listed in cells B1 to B3 (salary, freelance work, investments) and your expenses in cells C1 to C5 (rent, food, transportation, entertainment, utilities). To calculate your total income, you'd use =SUM(B1:B3). To calculate your total expenses, you'd use =SUM(C1:C5). These basic addition operations form the basis for more complex financial analysis.

Subtraction

Subtraction is just as easy. You can use the minus sign (-) to subtract one number from another. If you want to subtract the value in cell B1 from the value in cell A1, you'd use the formula =A1-B1.

Continuing with our income and expenses example, to calculate your net income (income minus expenses), you would subtract your total expenses from your total income. Assuming your total income is in cell B4 and your total expenses are in cell C6, your formula would be =B4-C6. This tells you exactly how much money you have left over each month after covering your expenses.

Multiplication

Multiplication comes in handy when you're calculating things like interest or returns on investments. You use the asterisk (*) to multiply numbers. For example, if you want to multiply the values in cells A1 and B1, you'd use the formula =A1*B1.

Imagine you're calculating the future value of an investment. If you invest $1,000 and expect a 5% annual return, you can calculate the return for the first year using multiplication. If your investment amount is in cell A1 and your interest rate is in cell B1 (expressed as a decimal, e.g., 0.05), your formula would be =A1*B1. This gives you the dollar amount of your return.

Division

Division is useful for calculating percentages or ratios. You use the forward slash (/) to divide numbers. If you want to divide the value in cell A1 by the value in cell B1, you'd use the formula =A1/B1.

Let's say you want to calculate what percentage of your income is spent on rent. If your rent payment is in cell C1 and your total income is in cell B4, you'd use the formula =C1/B4. To display this as a percentage, you can format the cell as a percentage by clicking the “Format” menu, selecting “Number,” and then choosing “Percent.”

Commonly Used Finance Formulas

Now that we've covered the basic arithmetic formulas, let's move on to some more advanced formulas that are particularly useful in finance. These will help you with everything from calculating loan payments to determining the future value of your investments.

PMT (Payment)

The PMT formula calculates the payment for a loan based on constant payments and a constant interest rate. It's super useful for figuring out your monthly mortgage payment, car loan payment, or any other type of loan payment. The syntax is =PMT(rate, nper, pv, [fv], [type]).

• rate: The interest rate per period. If your interest rate is an annual rate, you'll need to divide it by 12 to get the monthly rate.
• nper: The total number of payment periods. For a mortgage, this would be the number of months you'll be making payments (e.g., 30 years * 12 months/year = 360 months).
• pv: The present value, or the initial loan amount.
• fv (optional): The future value, or the cash balance you want after the last payment is made. If you're paying off a loan completely, this is usually 0.
• type (optional): When payments are due. 0 for payments due at the end of the period, 1 for payments due at the beginning. If omitted, it defaults to 0.

For example, let's say you're taking out a mortgage for $200,000 at an annual interest rate of 4%, with a loan term of 30 years. Your formula would be =PMT(0.04/12, 360, 200000). This will give you the monthly payment amount. Note that the result will be a negative number, as it represents an outflow of cash.

FV (Future Value)

The FV formula calculates the future value of an investment based on a constant interest rate. It's great for projecting how much your investments will be worth in the future. The syntax is =FV(rate, nper, pmt, [pv], [type]).

• rate: The interest rate per period.
• nper: The total number of payment periods.
• pmt: The payment made each period. If you're making regular contributions to the investment, this is the amount you're contributing each period.
• pv (optional): The present value, or the initial investment amount.
• type (optional): When payments are due. 0 for payments due at the end of the period, 1 for payments due at the beginning. If omitted, it defaults to 0.

For instance, let's say you invest $5,000 today and plan to contribute $200 per month for 20 years, with an expected annual return of 7%. Your formula would be =FV(0.07/12, 20*12, -200, -5000). The negative signs are used because these are cash outflows from your perspective. This formula will show you the projected future value of your investment.

PV (Present Value)

The PV formula calculates the present value of an investment. It helps you determine how much a future sum of money is worth today, given a certain discount rate. The syntax is =PV(rate, nper, pmt, [fv], [type]).

• rate: The discount rate per period.
• nper: The total number of payment periods.
• pmt: The payment made each period.
• fv (optional): The future value, or the cash balance you want.
• type (optional): When payments are due. 0 for payments due at the end of the period, 1 for payments due at the beginning. If omitted, it defaults to 0.

Suppose you want to have $100,000 in 10 years, and you expect an annual return of 6%. You want to know how much you need to invest today. Assuming you make no additional contributions, the formula would be =PV(0.06, 10, 0, 100000). This tells you how much you need to invest today to reach your goal.

IPMT (Interest Payment)

The IPMT formula calculates the interest portion of a loan payment for a specific period. This is useful for understanding how much of each payment is going towards interest versus principal. The syntax is =IPMT(rate, period, nper, pv, [fv], [type]).

• rate: The interest rate per period.
• period: The period for which you want to calculate the interest payment.
• nper: The total number of payment periods.
• pv: The present value, or the initial loan amount.
• fv (optional): The future value, or the cash balance you want after the last payment is made.
• type (optional): When payments are due. 0 for payments due at the end of the period, 1 for payments due at the beginning. If omitted, it defaults to 0.

Using our earlier mortgage example ($200,000 loan at 4% annual interest over 30 years), if you want to know the interest portion of your first payment, the formula would be =IPMT(0.04/12, 1, 360, 200000). This tells you how much of your first payment is going towards interest.

PPMT (Principal Payment)

The PPMT formula calculates the principal portion of a loan payment for a specific period. This complements the IPMT formula and helps you understand how much of each payment is reducing the loan balance. The syntax is =PPMT(rate, period, nper, pv, [fv], [type]).

• rate: The interest rate per period.
• period: The period for which you want to calculate the principal payment.
• nper: The total number of payment periods.
• pv: The present value, or the initial loan amount.
• fv (optional): The future value, or the cash balance you want after the last payment is made.
• type (optional): When payments are due. 0 for payments due at the end of the period, 1 for payments due at the beginning. If omitted, it defaults to 0.

Continuing with our mortgage example, to find out the principal portion of your first payment, the formula would be =PPMT(0.04/12, 1, 360, 200000). This tells you how much of your first payment is reducing the loan principal. By adding the results of IPMT and PPMT for the same period, you'll get the total payment amount, which should match the result from the PMT formula.

Conditional Formulas

Conditional formulas allow you to perform different calculations based on certain conditions. The most common conditional formula is the IF function. It allows you to create dynamic spreadsheets that respond to changes in your data.

IF

The IF formula checks if a condition is met and returns one value if it's true and another value if it's false. The syntax is =IF(logical_expression, value_if_true, value_if_false).

• logical_expression: The condition you want to check. This could be a comparison like A1>100, B2="Yes", or any other expression that evaluates to true or false.
• value_if_true: The value to return if the condition is true.
• value_if_false: The value to return if the condition is false.

For example, let's say you're tracking your expenses and want to flag any expense that's over $100. If your expense amount is in cell C1, you could use the formula =IF(C1>100, "Over Budget", "Within Budget"). If the expense is greater than $100, the formula will return "Over Budget"; otherwise, it will return "Within Budget".

You can also nest IF statements to create more complex conditions. For instance, you could have multiple budget categories and different thresholds for each. The possibilities are endless!
