Tips are weather. Base pay is climate.
When 50–70% of your income arrives in tips, budgeting on last Friday's take is how rent gets missed in February. This calculator splits your income into the guaranteed base and the variable tip share — so you can build fixed bills on the floor and aim the upside at savings and debt.
Servers and bartenders use it to answer "can I afford this apartment?" honestly — fixed bills go against the guaranteed base-pay floor, tips go to savings and debt. It is the antidote to budgeting on your best Friday.
For full-service restaurant servers, typically 60–85%. Bartenders in busy venues can top 90%. That variability is exactly why lenders and landlords discount tip income — and why your own budget should too.
Yes — tips are taxable income. Employers withhold on reported tips, and under the 2025 tax law, qualifying tips up to $25,000 are deductible from federal income tax through 2028 (phasing out at higher incomes) — but Social Security and Medicare tax still applies. Report them all; the deduction happens on your return, not by under-reporting.
Two-account method: all income lands in one account, and you pay yourself a fixed weekly "salary" into a spending account sized to your floor. Fat weeks build the buffer in the first account; lean weeks draw it down. After 3–6 months you have a self-insuring income smoother.
