Profit at different delegated stakes
Your commission revenue rises with delegated stake; your vote and server cost is fixed. Each row is a different amount of stake delegated to you at your inputs — the break-even row, where commission finally covers the vote bill, is marked.

The vote-cost wall nobody warns you about
Every Solana staking calculator shows you a yield — 7%, 8%, pick a number — and none of them tell you what it actually costs to be the validator earning it. That yield belongs to the delegators. The operator's income is a commission, a slice of the inflation and Jito MEV rewards their delegators collect, and it only grows if stake flows in. Sitting against that income is a cost most people never see: the vote transaction. A Solana validator votes almost every slot, each vote pays a fee, and full-time that is on the order of one SOL a day — around 365 SOL a year — paid whether you have a thousand SOL delegated or ten million. That is the wall. A small validator pays the same vote bill as a giant and earns a commission on a tiny stake, so it loses money every epoch. The break-even delegated stake this calculator prints is the honest entry ticket: the amount of delegation you have to attract before the commission covers the vote fees and the server. It is usually millions of dollars of stake, which is why most independent validators run at a loss and survive on foundation delegation programs or run a liquid-staking token to bootstrap deposits. If you are a staker rather than an operator — deciding whether to run your own or delegate your own coins — that is a different calculation, and the validator vs pool calculator is the one for it. To size the plain staking yield you would earn as a delegator, use the staking rewards calculator, and to see the per-transaction fees behind the vote cost, the Solana transaction cost tool.
The math
Let the delegated stake be D SOL at price P. Delegators earn inflation at APR i and Jito MEV at APR m. The operator keeps a commission c on inflation and cm on MEV, so annual commission revenue in SOL is D · (i/100 · c/100 + m/100 · cm/100). Writing the effective take rate as r = i·c/10⁴ + m·cm/10⁴, revenue is simply D · r SOL per year.
The cost side is fixed. Vote fees are vote · 365 SOL a year, and the server converts to SOL as server · 12 ÷ P. Total cost in SOL is voteSOL + serverSOL. The operator's net profit is (D · r − voteSOL − serverSOL) · P dollars a year. Setting net to zero gives the break-even delegated stake: D* = (voteSOL + serverSOL) ÷ r. Because the cost is fixed and revenue is linear in stake, every SOL above D* is pure margin and every SOL below it is a subsidy you pay. This ignores skipped-slot penalties, epoch-to-epoch reward variance, the commission other validators charge you nothing for, price moves in SOL between earning and selling, and taxes — so read the break-even as the structural entry point, not a guaranteed profit line.
