A customer should not have to guess what “three payments” means. Does that include the deposit? When is the first installment due? Is there a fee? What work does the total actually cover?
The Payment Plan Builder helps you put those numbers on one page. It can support an HVAC service proposal or another defined job. The goal is a schedule both sides can read before agreeing, not a smaller monthly number that hides the total.
Start with the scope of work
Write down the service, the price, and what is excluded. For a maintenance arrangement, identify the visits or services covered and the period involved. Decide how changes, cancellations, and extra work will be handled through your normal reviewed terms.
Do this before opening the calculator. Dividing an unclear price into neat payments does not make the underlying offer clear. It can simply spread the misunderstanding across several due dates.
A fixed service paid over time is also different from an automatically renewing membership. This tool divides one billed total. It does not establish subscription terms or recurring maintenance revenue.
Work through a fictional schedule
Enter the following illustrative numbers:
- Total price: $1,200.
- Deposit percent: 25%.
- Number of payments: 3.
- Payment plan fee: 0%.
The deposit is $1,200 × 25%, or $300. That leaves $900, divided into three installments of $300. The complete schedule has four money movements: the deposit and three later payments. Together they equal the agreed $1,200.
Now compare a hypothetical 5% fee, without treating that fee as a recommendation. The tool first increases the billed total to $1,260. The deposit becomes $315, and each of the three installments is also $315. The fee changes both the total and the deposit because the deposit percentage applies after the fee.
Try the Payment Plan Builder
Start with the illustrative example, then use clearly defined figures from your own records. The tool is free; the notes below explain what its outputs do and do not mean.
Your details
Flat percentage of the full price, added before the deposit. This is not APR. Confirm permitted fees and the agreed total.
What you built
The schedule. Print it and attach it to the invoice.
| When | Amount |
|---|---|
| Deposit today | $1,440.00 |
| Payment 1 | $560.00 |
| Payment 2 | $560.00 |
| Payment 3 | $560.00 |
| Payment 4 | $560.00 |
| Payment 5 | $560.00 |
| Payment 6 | $560.00 |
| Total collected | $4,800.00 |
Show the total of $4,800.00, the $1,440.00 deposit, and the complete schedule together. The final payment is $560.00.
Amounts reconcile to cents; the final installment carries any rounding remainder. These are proposed amounts, not an authorization to charge. Confirm the schedule, fees, and payment consent in your actual agreement.
What this assumed
- This builds a simple in-house schedule. It is not a credit product and it does not compute APR.
- The fee is a flat percentage of the full price, added before the deposit is calculated; it is not an APR or a charge authorization.

How to run it, step by step
- 1Enter the agreed total. Total price is the amount for the defined work. Confirm what it includes before dividing it into payments.
- 2Choose a deposit and installments. Deposit percent applies to the billed total. Number of payments counts installments after the deposit, not the deposit itself.
- 3Keep fees explicit. Payment plan fee increases the whole billed total before the deposit is calculated. Start at zero unless an appropriate, reviewed fee is part of the actual agreement.
- 4Add real dates outside the model. The table numbers the payments. Put the actual due dates, payment method, and agreed terms into the customer's reviewed schedule.
How to read what it gives you
- The calculated schedule is a proposal, not a signed agreement, credit decision, payment collection, or authorization to charge a card.
- A maintenance service paid in installments remains one defined sale. The calculator does not create a recurring subscription or prove future revenue.
The tool is free, it does not expire, and you can put it on your own website if you want it there. Nothing on this page is locked.

Check the table against the agreement
The display uses numbered payments and a month count. It does not know your actual calendar, when a customer signs, or whether payment should follow a completed milestone. Add dates explicitly and confirm that they match the agreement.
Rounding deserves a check as well. Some totals do not divide evenly into cents. When that happens, reconcile the final installment so the deposit and payments add to the precise agreed total. A display rounded to two decimal places is not a substitute for that final check.
The tool cannot decide whether you should extend credit or whether a fee is appropriate. It also does not obtain permission to charge a saved card. Keep those decisions in the payment and agreement process you actually use.

Keep the customer's private details in the authorized record. The shareable version should contain only what is needed to understand and approve the schedule.
Check your own cash timing
A workable customer schedule also needs to fit delivery costs. List when labor, materials, travel, and other costs occur. A deposit that looks convenient on the screen may not cover the work you must fund before later payments arrive.
Track scheduled money separately from collected money. An installment appearing in a table is not cash in the bank. Assign a person to reconcile receipts and review overdue items through the agreed process, rather than relying on the schedule to enforce itself.
Open the Payment Plan Builder, compare a couple of clear scenarios, and take the one you are considering back to the actual scope and terms. If your site needs a clearer path from proposal to payment, start with that customer journey.
Questions people actually ask
Does the deposit count as one of the payments?
No. The tool first calculates the deposit and then divides the remaining balance by Number of payments.
Does this tool collect money or store a card?
No. It displays a payment schedule. Collection and any recurring authorization need an appropriate payment process and a clear agreement.
Can I charge a payment-plan fee?
The calculator can model a fee but does not determine whether a particular arrangement or fee is permitted. Review the actual terms and applicable requirements before offering it.
