An advertised annuity total, a quoted cash option and discounted net payments describe different cash flows; compare them only after choosing explicit tax, timing and valuation assumptions.
Start with the actual quote and annual cash flows
An advertised jackpot is an annuity total, not an amount automatically available at the claim counter. Enter the published cash quote when you have one; otherwise the percentage control remains an explicit estimate. Selecting quote mode makes the percentage inactive, so the calculator never adds both cash amounts. The annual payment count and growth determine a single gross installment schedule whose raw amounts reconcile to the advertised total. Zero growth gives equal payments. Very small positive growth is evaluated with stable normalized weights instead of subtracting nearly equal powers.
Choose whether the first installment occurs at valuation or one annual period later. An optional first-payment date labels the annual sequence, retaining its original day across leap years where possible. These are whole annual planning intervals, not daily interest calculations or a verified claim timetable. Each date and time exponent is exported with its installment. Review the entered contract terms separately: the calculator does not confirm that a particular game offers your quote, growth, count or payment dates.
Separate incremental final tax from withholding
The selected 2025 or 2026 federal ordinary-income schedule is held constant for every modeled payment year. Enter other annual taxable income after deductions; the model integrates the additional prize through the remaining tax bands without taking another standard deduction. This estimates incremental federal liability, rather than automatically charging the highest bracket on every small installment. A manual federal flat-rate assumption is also available for an explicitly simplified scenario, including zero tax controls.
Federal withholding is displayed separately. In the regular model, total lottery proceeds above $5,000 trigger 24% withholding even when individual installments are smaller. Withholding is a payment toward final tax, so it is not subtracted again from final-tax net cash. Wager-cost adjustments, backup withholding, nonresident rules, credits and detailed return calculations are excluded. State/local tax uses your entered flat assumption or the stated Pennsylvania cash-prize model at 3.07%. Restored old jurisdiction rates remain prominently unverified illustrations. Residency, source-state interactions and local sourcing are not established by selecting a jurisdiction label.
Compare present value, sensitivity and common-horizon illustrations
Compare estimated net cash at valuation with the estimated present value of the net annuity at that same time. The nominal sum of decades of installments is shown separately, because it does not share the cash option's timing basis. The timeline contains annual net payments, cumulative discounted payments and a net cash reference; each series has a distinct meaning even though the axis uses USD. The sensitivity view values the same final-tax schedule at different after-tax annual-effective discounts.
A reported break-even is forward-checked against the cash benchmark and includes its residual. The search domain is 0–30%; no root inside that interval does not become a fabricated endpoint answer. Immediate equal cash flows can have no unique discount, and mixed-sign cash flows are qualified. An optional common-horizon investment illustration uses a separate entered gross return and a flat drag on positive growth. Inflation affects separately labeled purchasing-power amounts. Neither assumption turns discounting into a reliable investment forecast, and unrepresentable optional projections become unavailable without inventing a balance.
Keep the raw receipt and financial sharing explicit
The annual schedule and CSV expose gross installments, estimated federal and state/local final tax, net cash, federal withholding, later settlement estimates, discount factors, log factors and present values. Display amounts round independently; a small difference between separately rounded components does not change the unrounded ledger. At extreme numeric scales a factor may be unrepresentable while its combined discounted amount remains finite, so the raw log factor is retained and the standalone factor is left unavailable. This is finite-double planning arithmetic, not a cent-posted tax return.
Loading a recognized previous numeric record preserves its actual stored meaning without inferring locale, currency or a different intended amount. Unknown records require explicit Reset, and recognized invalid drafts require an edit to their own field. Saving on this device is opt-in. Share and Embed begin with a clean link containing no financial values; including values requires a preview of every retained input, including inactive drafts. No ticket, identity, contact or claim information is needed. Downloaded or shared files remain under your control and can reveal the assumptions to their recipients.
