Time Calculator

Look at the detailed step-by-step procedure to calculate the monthly payments easily and quickly. Go through the below steps carefully.

• Let us know the details of a mortgage amount, interest rate, and mortgage terms.
• After that apply the formula and keep all the details in the formula.
• Then simplify it and you will get the monthly payments.

Now we will look into the terms that are used in the Time Calculator.

Mortgage Amount:  The amount you need to spend on a mortgage. Original principal mortgage amount when calculating the current mortgage.

Mortgage Term:  The time left when calculating the given mortgage.

Interest Rate: Annual interest rate on the loan. This interest rate is charged differently.

Monthly Payment:  The amount that you need to pay on a monthly basis towards interest and principal.

Now, look into the formula, that you need to calculate the Time Differences.  

PMT = PV i(1+i)ⁿ/ (1+i)ⁿ - 1

Where,

PMT is the mortgage payment amount.

PV is the present value.

n is the number of mortgage payments.

i is the period interest rate.

Example:

Question: Suppose you wish to acquire a car that costs $34550. And to make the down payment of $1000 along with the interest of 2% on 3 years with a $15500 loan.

Solution:

Given, Interest = 2%, Mortgage amount = $34550, Mortgage term = 3 years.

As we know the Time Difference formula,

PMT = PV i(1+i)ⁿ/ (1+i)ⁿ - 1

= [$15500 * (0.02/12)( 1+ 0.02/12)³⁶] / [( 1+ 0.02/12)³⁶ - 1]

= [$15500 * (0.001)( 1+ 0.001)³⁶] / [( 1+ 0.001)³⁶ - 1]

Monthly payment = $ 989.60

Look into the guidelines that are given below to add, subtract, multiply and divide time easily.

Adding Time

• Firstly, write down the values that were given in the problem.
• Add hours, seconds, and minutes separately.
• Then, convert mins to hours and seconds to minutes if possible.
• Then substitute the values in the formula like Time = hours + minutes + seconds.
• Again add hours, seconds, and minutes separately.
• Finally, you will get the answer.

Subtracting Time

• Firstly, write down the value that was given the problem.
• Then, convert the values to the smallest unit in them.
• Now, subtract the converted values.
• Again convert the result to the desired unit.

Multiplying Time

• Primarily, note down the values that were given in the problem.
• Multiply each unit separately.
• If there is a possibility then convert the values.
• Add the converted units.
• Then again add the units separately.
• Finally, you will get the result.

Dividing Time

• The first and foremost thing you need to do is write down the value that was given in the problem.
• Convert the numerator to the smallest unit until you will get the number that should be divisible by 5.
• Now, make the division.
• Finally, you will get the answer.
• Convert that answer into the desired unit.

Examples of Adding, Subtracting, Multiplying, and Dividing Time

Question 1: Add time of 2 h 53 min + 2 h 8 min 22 s + 46 s

Solution:

Given, 2 h 53 min + 2 h 8 min 22 s + 46 s

Now, add units seperately

hours = 2 h + 2 h = 4 h

minutes = 53 min + 8 min = 61 min

seconds = 22 s + 46 s = 68 s

Convert, units where possible

minutes = 61 min = 1 h 1 min

seconds = 68 s = 1 min 8 s

Substitute the converted values in formula.

hours + minutes + seconds =

4 h + 1 h 1 min + 1 min 8 s

Add hours, minutes, and seconds separately

hours = 4 h + 1 h = 5 h

minutes = 1 min + 1 min = 2 min

seconds = 8 s

When there's nothing left to add, we write a note down the result.

5 h + 2 min + 2 s = 5 h 2 min 8 s

Hence the addition of time is 5 h 2 min 8 s.

Question 2: Subtract Time of 1 day - 11 min 55 s

Solution:

Given, 1 day - 11 min 55 s

Convert time values to the smallest unit

1 day = 86400 s

11 min 55 s = 715 s

Subtract the converted values

86400 s - 715 s = 85685 s

Convert the result to the desired unit:

85685 s = 23 h 48 min 5 s

Hence the subtraction of time is 23 h 48 min 5 s.

Question 3: Multiply Time of 2 h 43 min 11 s * 6

Solution:

Given, 2 h 43 min 11 s * 6

Multiply each unit separately

hours = 2 h * 6 = 12 h

minutes = 43 min * 6 = 258 min

seconds = 11 s * 6 = 66 s

Convert each unit if possible.

hours = 12 h

minutes = 258 min = 4 h 18 min

seconds = 66 s = 1 min 6 s

Add the converted units

hours + minutes + seconds =

12 h + 4 h 18 min + 1 min 6 s

Again, change the units.

(12 h + 4 h) + (18 min + 1 min) + 6 s =

16 h 19 min 6 s

Hence the multiplication of time is 16 h 19 min 6 s.

Question 4: Divide the Time by 2 weeks / 5?

Solution:

Given, 2 weeks / 5

Convert the numerator to a smaller unit and it should be divisible by 5.

2 weeks = 2 * 7 days =14 days

20 days = 20 * 24 h = 480 h

504 h = 480 * 60 min = 28800 min

Make the division

28800 min / 5 = 5760 min

Convert to the desired unit

5760 min = 99 h 48 min.

Hence the division of time is 99h 48 min.
