The calculator works out a level loan payment from amount, rate and months. Invented cases then test a payment in a cash book, a cash ratio, a cash reserve check and an advance comparison. Nothing typed is sent anywhere.
Cash book calculator: a Port Charlotte, FL plumbing and HVAC contractor's month of cash in and out
A cash book lists money in and money out for a period, from the opening balance to the closing one. The calculator gives the loan payment; the cash book shows whether the month can carry it. Invented case: a Port Charlotte plumbing and HVAC contractor checks a $30,000 loan over 24 months at an annual rate of 11.0% against one month.
| Line | Amount |
|---|---|
| Opening cash | $14,200 |
| Customer payments received | $61,400 |
| Crew payroll | $27,600 |
| Supply house invoices | $18,900 |
| Rent and utilities | $4,300 |
| Insurance | $2,150 |
| Loan payment | $1,398.24 |
| Closing cash | $21,251.76 |
One month is only a start: run the same sheet for a month with slower collections, too. A contractor checking its month this way may be a one-person shop: 105 plumbing, heating and air-conditioning contractors in Charlotte County, FL had no paid employees in 2024, by the Nonemployer Statistics count (NAICS 23822).
Cash ratio calculator, worked by hand for a Port Charlotte, FL home builder pricing a telehandler
A cash ratio divides cash and cash equivalents by the bills due within the year. It is not something the calculator on this page works out, so here it is by hand. Invented case: a Port Charlotte home builder holds $46,000 in cash against $82,000 of bills due within the year, a cash ratio of 0.56.
It is pricing an invented $118,000 telehandler with $15,000 down. Paying the down payment drops the ratio to 0.38. Illustration only, invented figures: financing the other $103,000 over 60 months at an annual rate of 9.25% adds a monthly payment of $2,150.63, the figure the calculator returns for those inputs.
Builders of this kind form a group of their own in the county data: 186 residential building construction establishments with paid staff were in Charlotte County, FL in 2023, and 76.3% of them had fewer than five employees (CBP, NAICS 2361).
Cash reserve ratio calculator steps for a Port Charlotte, FL retailer adding gondola shelving
Here the cash reserve ratio means cash on hand divided by average monthly operating costs: the number of months the business could run on what it holds. Invented case: a Port Charlotte retailer holds $38,000 and spends about $21,500 a month, and wants $9,400 of gondola shelving.
| Choice | Cash on hand | Monthly costs | Months of reserve |
|---|---|---|---|
| No shelving | $38,000 | $21,500 | 1.77 |
| Pay cash for the shelving | $28,600 | $21,500 | 1.33 |
| Finance it over 24 months at 10.5% a year | $38,000 | $21,935.93 | 1.73 |
Financing keeps more months of reserve in this example, at the cost of $1,062.32 in interest over the term. The payment used, $435.93, is what the calculator gives for $9,400 at an annual rate of 10.5% over 24 months.
Merchant cash advance calculator math for a Charlotte County, FL HVAC shop stocking condensers
The calculator on this page does not price a merchant cash advance; the merchant cash advance page has an advance calculator. The math is short enough to do by hand. Invented case: a Charlotte County HVAC shop stocking condensers for its install crews looks at a $16,000 advance with a 1.24 factor rate and a 10% holdback on $1,100 of average daily card sales.
| Option | Collected or repaid in all | Cost | How long |
|---|---|---|---|
| Merchant cash advance | $19,840 | $3,840 | about 181 business days at $110.00 a day |
| Loan at an annual rate of 14.0% | $16,947.81 | $947.81 | 9 payments of $1,883.09 |
In these invented figures the loan costs less, but the advance flexes with card sales while the loan payment does not. Short-term stock needs can also go to working capital loans. If that payment fits the month, the next move is the request form or a call to (941) 419-2666.
