Project Deposit and Payment Schedule Calculator

For web design, development, marketing or any fixed-price project, enter the total price, the deposit you ask for up front and how many milestone payments follow, and this calculator lays out the payment schedule. It splits the remaining balance evenly, puts any leftover cent on the final payment and shows what share each payment is of the total.

What you enter

  • Total project price
  • Deposit
  • Payments after the deposit

What you get

  • Deposit due before work starts
  • Balance after the deposit
  • Each milestone payment
  • Final payment

How it works

  1. Enter the total project price you quoted.
  2. Set the deposit as a percent of the total. Many freelancers and studios ask for between a quarter and a half before starting.
  3. Choose how many payments follow the deposit, such as one on design approval and one at launch.
  4. Copy the table into your proposal or contract so the client sees exactly what they pay and when.

Why deposits protect small businesses

A fixed-price project means you do weeks of work before seeing most of the money. If the client changes their mind halfway, a deposit means you are paid for the time already given. It also filters out clients who are not ready, because someone willing to pay a deposit has usually decided.

Milestone payments do the same through the rest of the project. Instead of one large bill at the end, the client pays in steps that match the work they have approved, which spreads their cost and keeps your cash flow steady.

Writing the schedule into your proposal

Describe each payment in words beside the amount: deposit on signing, second payment when the homepage design is approved, final payment before launch. A list of numbers alone invites questions, while a list of events tells the client what has to happen for each invoice to be sent.

Round amounts where it helps. If the even split leaves awkward cents, many people adjust the price slightly or let the final payment absorb the difference, which is what this calculator does. Either way, check that the payments add up to the quoted total before you send the proposal.

Tips

  • Take the deposit before you book the work into your calendar. It confirms the client is committed and covers your time if they disappear.
  • Tie each milestone to something the client can see, such as approved designs or a staging site, not to a date that can slip.
  • Keep the final payment due before launch or file handover where you can. Once the site is live, the client has little reason to hurry.
  • Say in the contract whether the deposit is refundable if the project is cancelled.
  • On larger projects, more milestones keep cash coming in and keep both sides checking progress.

Frequently asked questions

How do I work out a deposit?

Multiply the project price by the deposit percent. A $4,000 project with a 50% deposit needs $2,000 up front, and the other $2,000 is split across the remaining payments.

How are the milestone payments split?

The balance after the deposit is divided evenly by the number of milestones and rounded down to the cent, and the last payment takes any leftover cents so the total is exact. $1,000 over 3 milestones is $333.33, $333.33 and $333.34.

What deposit percent should I ask for?

It depends on your risk and your market. A higher deposit protects you if the client walks away, and a lower one is easier to agree to. Choose a figure you can explain and use it consistently.

Should tax be included?

Enter the price the way you invoice it. If you charge sales tax, either enter the total with tax or calculate tax on each invoice. This tool does not add tax.

Is this contract or legal advice?

No. It only does the arithmetic. How deposits and cancellations work should be written in your contract, and a lawyer can check the wording.
