To convert years to months, use this simple rule:
Examples:
This years to months conversion is based on the standard calendar year having 12 months. Month length can vary (28 to 31 days), and leap years change the number of days in a year, but they don’t change the 12-month structure.
A standard year has 12 months. This is the base rule for converting years to months.
Multiply the number of years by 12.
Example: 3 years × 12 = 36 months.
2 years equals 24 months (2 × 12 = 24).
5 years equals 60 months (5 × 12 = 60).
10 years equals 120 months (10 × 12 = 120).
0.5 years equals 6 months (0.5 × 12 = 6).
1.5 years equals 18 months (1.5 × 12 = 18).
2.5 years equals 30 months (2.5 × 12 = 30).
Yes. If the years value has decimals, the months result can be a decimal too. If you need whole months, round to the nearest month, or round down for a safer estimate.
Convert the full years to months, then add any extra months.
Example: 4 years and 3 months = (4 × 12) + 3 = 51 months.
Divide months by 12.
Example: 30 months ÷ 12 = 2.5 years.
For calendar month counts, yes, 1 year is 12 months. This stays true even in leap years because leap years add a day, not a month.
No. A leap year still has 12 months. Leap years only change the number of days in the year.
Months have different day counts, from 28 to 31 days. That doesn’t change year-to-month conversion, but it matters when you convert years to days or weeks.
Use the same rule: years × 12.
Example: 7 years old = 84 months old.
Multiply the years in the term by 12 to get the number of monthly payments.
Example: a 15-year term = 180 months.
20 years equals 240 months (20 × 12 = 240).
25 years equals 300 months (25 × 12 = 300).
30 years equals 360 months (30 × 12 = 360).
Remember this: months = years × 12. It works for whole years and decimal years.
