Calculator for How Long Money Will Last

Determine how long your savings will last with our financial calculator. This tool helps you estimate the duration your money will cover based on your monthly expenses and savings rate.

How This Calculator Works

The "How Long Money Will Last" calculator estimates how many months or years your savings will cover based on your monthly expenses and savings rate. It assumes you spend money at a consistent rate and don't add to your savings during the period.

The Formula

The basic formula is:

Duration (months) = Total Savings / Monthly Expenses

For example, if you have $10,000 saved and spend $1,000 per month, your money will last 10 months.

Key Assumptions

Your expenses remain constant each month
You don't add to your savings during the period
You don't receive any additional income during the period
There are no unexpected costs or changes in your financial situation

This calculator provides an estimate. Actual results may vary based on your specific financial situation and any changes in your income or expenses.

Worked Example

Let's say you have $15,000 saved up and plan to spend $1,200 per month. Here's how the calculation works:

Duration = $15,000 / $1,200 per month = 12.5 months

This means your $15,000 will last for 12 months and 15 days (15 days = 0.5 months × 30 days/month).

This example shows that with consistent spending, your savings will cover your expenses for slightly more than a year.

Interpreting Results

The calculator provides a simple duration estimate. Here's what the results mean:

Positive number: Your savings will cover your expenses for this many months
Zero or negative: Your expenses exceed your savings, meaning you need to adjust your spending or find additional income

Remember that this is a simplified calculation. Real-world factors like inflation, unexpected expenses, or changes in your financial situation may affect the actual duration.
