Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Apply an explicit planning frequency to every amount, divide annual equivalents by twelve and separately sum income and expenses. Subtract expenses to show a monthly planning balance.
Annual=amount×frequency factor; monthly equivalent=annual/12; balance=income−expenses
Worked example
Monthly income 3000, housing 1200/month, groceries 100/week, insurance 600/year and utilities 100/month give monthly-equivalent expenses 1783.3333 and a balance of 1216.6667.
Assumptions and input details
Planning factors are explicitly 365 days, 52 weeks, 26 fortnights, 12 months, 4 quarters or 1 year. These conventions are not a dated cash-flow forecast and can differ from actual pay periods. Enter take-home income or another consistent basis; taxes are not inferred. All amounts share one currency, with no exchange conversion. Positive balance is unallocated money, not automatically an investment or savings deposit. A zero-income balance percentage is undefined.

Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Split a shared expense by equal or weighted shares and calculate who pays whom. Keep rounded shares and transfers balanced exactly to your selected currency precision.
Estimate depletion, a reorder date and whole packs to buy from your own average daily use.
Compare future replacement cost, fixed-cash purchasing power and an entered nominal investment return.
