Frequently asked questions

What is Burn Rate?
Burn Rate is the rate at which you spend money per month without income coming in. It's how long the reserves you have will last. It's often used in the context of startups, but it can also be used in personal finance.
How many months of burn rate should you have?
Financial experts recommend that you have an emergency reserve of at least 3-6 monthly expenses. If less than 3 monthly expenses are considered high risk, you should accelerate the accumulation of reserves to the level of 6 monthly expenses as soon as possible.
How do you reduce the Burn Rate?
The way to reduce the burn rate is to cut unnecessary expenses like membership fees, out-of-home meals, negotiate rents or service charges, and find ways to increase additional income so that the reserves last longer.
