Split the project total

Worked example

40% deposit on a $4,000 project

The deposit is $1,600 and the remaining balance is $2,400. If that balance is split into three payments, each is $800. Every displayed payment always adds back to the exact project total.

Rounding

The final payment handles any rounding difference

Payments are rounded for the selected currency. If the balance cannot be divided evenly, the final payment absorbs the smallest remaining difference so the schedule still adds up to the project total.

Use the result

Review a payment before adding it

Your project total and payment schedule are planning inputs. When you choose an invoice action, review the customer-facing payment amount and description before adding it to the invoice.

Deposit calculator FAQ

Does this create an invoice automatically?

No. Choosing an invoice action opens a review step in the editor. Nothing changes until you confirm it.

Can the deposit equal the full project total?

Yes. The result becomes a full upfront payment with no remaining balance.

Which currencies are supported?

The calculator uses InvoiceCraftly’s currency catalog, including currencies with zero or three decimal places.

Is this accounting or contract advice?

No. Confirm the payment schedule, tax treatment, wording, and contract terms appropriate to your work and location.
