Lynxshore Financial, a small-business funding service in Hattiesburg, MS, offers this loan calculator for gas station and convenience store owners. Enter a loan amount, an annual rate you choose and a term in months; it returns the monthly payment, total interest and total repaid. It does not quote rates or predict any partner's offer.
Three outputs, nothing more
- Monthly payment for a fully amortizing loan
- Total interest, summed over all the months you pay
- Total repaid: the amount borrowed plus all interest
Whatever rate you key in is the one used. Lynxshore does not publish rates; partners set them after review, and their offers may include other charges the calculator does not include.
Pricing a pump or canopy project with it
Common gas station loan uses are dispensers and payment systems, canopy and lighting, coolers, and store remodels. Enter the quote as the amount, try two or three terms, and compare the payments with what the store clears each month. The gas station funding page explains which type usually fits each need.
Equipment-only purchases
For dispensers or coolers, partners often structure the deal as equipment financing, sometimes with a down payment. Take any money down off the price first, then enter what is left.
Larger upgrades
Canopy replacements and store remodels usually go to a term loan. Use the project budget as the amount.
Gas station loan requirements to think about first
- Fuel and store sales from bank and card statements
- The station's fuel supply contract
- The lease or property ownership and its remaining term
- Every loan, lease and advance already being paid
None of these change the calculator's math, but they decide whether a partner offers a loan at all.
A worked run with hypothetical numbers
Illustration only: enter $73,400 for a dispenser and payment-system upgrade, a rate you want to test, and terms of 36, 48 and 60 months. The longer the term, the lower the monthly payment and the higher the total interest. Write the three monthly payments next to the station's average monthly surplus from the last year; the term where the payment fits comfortably, with room for a slow month, is the one to ask about.
Then repeat the run at a higher rate than you expect. If the payment still fits, the project has a margin of safety; if it only fits at the most optimistic rate, the plan is fragile.
Down payments and trade-ins, before you type the amount
Illustration only: a dispenser quote is $73,400. With 10% down ($7,340), the amount to enter is $66,060. If the supplier also credits $2,500 for the old units, enter $63,560. Running both versions shows how much the down payment changes the monthly figure.
Checking the payment against the margin it has to come from
Illustration only: new reach-in doors and a cooler are expected to add $1,150 a month of inside-store gross margin. If the calculator's payment at your test rate and term comes out at $900, the project leaves about $250 of that margin each month. If it comes out at $1,300, the equipment costs more each month than it earns until the term ends.
Fuel projects are checked the same way, using cents per gallon times gallons instead of store margin. The calculator gives the payment; the margin comes from your own records.
Gas station equipment financing that comes as a lease
This calculator models a loan. When a dispenser or cooler offer arrives as a lease, add up the lease payments over the term and any purchase price at the end, then compare that total with the calculator's total repaid for a loan of the same amount. The cheaper monthly figure is not always the cheaper total.
The equipment financing page compares fair market value and $1 buyout leases if you need the structures explained.
Outside the calculator's reach
It does not model buying a station, fuel margins, weekly figures, leases or merchant cash advances. Those need a conversation and, where relevant, the partner's own figures. Convenience store loans for stock rather than equipment usually go to inventory financing, which follows the sales cycle rather than a fixed schedule; the calculator still gives a rough monthly figure if you enter a term.
