How does this calculator work?
Monthly savings = Income − (Housing + Food + Transport + Health + Entertainment + Other). Savings rate = Savings ÷ Income × 100 %. Annual savings = monthly savings × 12. A savings rate of 20 % or more is the common benchmark; negative savings means spending exceeds income.
Formula
How this is calculated
A budget is simply the comparison between what comes in (income) and what goes out (expenses). This calculator groups spending into six common categories — housing, food, transport, health, entertainment, and other — and subtracts their total from your monthly net income to find monthly savings. Annual savings is just the monthly figure multiplied by 12.
The savings rate — savings ÷ income — is a key personal-finance metric. Financial planning guidelines vary: the 50/30/20 rule suggests 50 % to needs, 30 % to wants, and 20 % to savings; FIRE (Financial Independence) followers often target 50 % or more. A negative savings (spending above income) signals a deficit that will require either higher income, lower spending, or drawing on existing savings or credit.
Currency is not specified — enter any currency consistently and the ratios remain meaningful. The figures represent a single month; multiply by 12 for an annual picture or adjust to weekly/daily if your income cycle differs.
Frequently asked questions
A common rule of thumb is to save at least 20 % of net income. If you aim for financial independence, targeting 30–50 % or more dramatically cuts the years needed to build a retirement fund. Even starting at 5–10 % is valuable — consistency matters more than percentage when starting out.
Other covers anything that doesn't fit the listed categories: clothing, personal care, gifts, pet costs, education fees, and irregular bills such as annual subscriptions or car servicing. It's worth reviewing this category regularly — small recurring items accumulate quickly.
Enter your post-tax (net / take-home) income. The calculator doesn't compute income tax — if you need to estimate take-home pay from a gross salary, use a separate income-tax or payslip calculator first and enter the net result here.
