Bachelor party calculator — who's owed what, with the groom covered

Covering the groom, expense by expense

You decide which costs the groom doesn't pay for, one expense at a time.

• Mark the groom. Add everyone's names, then tap “Mark as groom” next to the groom. Tap it again to unmark the groom.
• The switch starts on. Every new expense has “The groom doesn't pay for this” switched on. Turn it off for anything the groom shares.
• What covered means. The groom is left out of that even split, so the groom's share is spread over the other guests in it. Who's in says Covered in the groom's row.
• An example. Eight people go: Casey is the groom, and Sam, Alex, Jo, Morgan, Riley, Jamie and Taylor are the guests. The switch is on for the $2400.00 house and the $700.00 welcome dinner, and off for $350.00 of groceries and house drinks and a $960.00 boat day. The shares come to $606.61 for each of the first five guests, $606.60 for each of the last two, and $163.75 for Casey.

Who paid, and how each expense is split

Anyone can pay for anything, and every expense can be split its own way.

• Anyone can pay. Choose who paid on each expense, one person or several. The groom can pay too, and the guests pay the groom back their shares.
• Even or exact. “Even” splits the cost across everyone checked in Who's in, except the groom when “The groom doesn't pay for this” is on. Choose “Exact” in the Split row to type each person's share.
• Exact means exact. On an exact split the switch is hidden and nothing is covered for you. Leave the groom's row empty if the groom doesn't pay.

Settling up, person to person

Once the expenses are in, the Who's owed what section shows who pays whom.

• Copy it to the group. Tap “Copy” and paste the result into your group chat. Each line says who pays whom and how much, to the cent.
• It stays on your phone. Everything you type stays on this device and is never sent anywhere. Come back later and pick up where you left off, or tap “Delete everything” for a clean slate.

Does the groom pay for anything?

That is up to your group, and the page decides nothing. With “The groom doesn't pay for this” on, the groom's share of that expense is spread over the guests. With it off, the groom pays that share like everyone else. You choose for each expense on its own.

What does “The groom doesn't pay for this” do?

It leaves the groom out of that expense's even split, so the groom's share is spread over the other guests who are checked in Who's in. Their shares still add up to the whole amount, and the groom's row says Covered.

Can I cover the groom on some expenses and not others?

Yes. The switch belongs to each expense. In the example above it is on for the $2400.00 house and the $700.00 welcome dinner, and off for the groceries and the boat day. A new expense always starts with it on.

What if the groom paid for something?

Choose the groom under Who paid, like anyone else. The guests pay the groom back their shares of it. If “The groom doesn't pay for this” is on, the groom's own share is spread over the guests too, so the groom is paid back all of it.

How do I cover the groom on an exact split?

On an exact split the switch is hidden, because “Exact” means the amounts you type. Leave the groom's row empty and type each guest's amount, so that for the $2400.00 house the seven guests' amounts add up to $2400.00.

What happens to a leftover cent?

When an expense will not divide evenly, the leftover cents go one at a time to the first guests in your list who share it. The split always adds up to the bill exactly. For example, the $2400.00 house over seven guests is $342.86 for the first five and $342.85 for the last two, which is why two guests above pay a cent less than the other five.

Is this calculator free?

Yes. It costs nothing to use, you do not need an account, and there is nothing to sign up for.

Where are the names and amounts kept?

On the device you are using, in this browser. Nothing you type is sent anywhere, and your work is still here the next time you open the page. To clear it, tap “Delete everything” under the calculator.

Can two people pay for the same thing?

Yes. Switch the Who paid row to “Several people” and type what each person paid. Each person's share of that expense is then divided among the payers in proportion to what each of them paid.

Why does it not tell everyone to pay one person?

The page only asks for a payment between two people who actually shared an expense. If two people never split a cost, nothing is owed between them, so nobody is asked to send money to someone they shared nothing with.
