Bill Split Calculator

Convention (and this calculator) tips on the pre-tax subtotal — tipping on tax rewards the government, not the server. An 18% tip on an $84 subtotal is $15.12 whether the tax line is 5% or 10%.

Equal splits are fastest and fair within a few dollars; groups with big order gaps can split the subtotal by consumption and share tax and tip proportionally. Whatever the method, decide before the check arrives — the math is easier than the negotiation.
