Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What formula does the home maintenance calculator use?
It uses annual reserve = home value x (maintenance rate / 100) and monthly reserve = annual reserve / 12. For example, a 350000 home at a 1 percent rate gives a 3500 annual reserve and about a 291.67 monthly reserve.
What maintenance rate should I use?
Leave the rate blank for the common 1 percent of home value per year guideline, or enter your own value from 0 percent to 5 percent. Older homes, climate, and condition can require more, so treat the result as a planning starting point.
Which inputs are accepted?
Enter a home value greater than zero through 1000000000 and an optional annual maintenance rate from 0 percent to 5 percent. Displayed amounts are rounded to two decimal places.
Do my values stay private, and is this financial advice?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter. This is a general planning estimate, not financial advice.
