MoneyKey Loan Calculator
Estimate your monthly payment and total repayment cost before you borrow. Enter your loan details below to see a breakdown of costs.
How to Use This Calculator
Enter the amount you want to borrow (MoneyKey offers $200 to $3,500 depending on the product), the APR (MoneyKey APRs typically range from 249% to 295%+), and your preferred loan term. The calculator will show you the estimated monthly payment and total cost of borrowing.
Understanding the Results
Pay close attention to the total repayment amount and cost per dollar borrowed. With MoneyKey's high APRs, a $1,000 loan could cost significantly more than the original amount borrowed by the time it is fully repaid. Make sure you can afford the monthly payments before accepting any loan offer.
Tips for Responsible Borrowing
Borrow only what you need, not the maximum amount you qualify for. Pay back your loan as quickly as possible to reduce total interest charges. There are no prepayment penalties with MoneyKey, so early repayment saves you money. Always compare offers from multiple lenders before deciding.
The Math Behind the Numbers
This calculator uses the standard amortization formula for a fixed-payment installment loan, which is the same formula banks and credit unions use for personal loans, auto loans, and mortgages. The formula is:
Payment = P × (r × (1+r)^n) / ((1+r)^n − 1)
Where P is the loan principal (the amount you borrow), r is the monthly interest rate (APR divided by 12, expressed as a decimal), and n is the number of monthly payments. The result is a level monthly payment that fully retires the loan by the end of the term. In the early months, most of each payment goes to interest; in the later months, most goes to principal. This is why paying extra early in the loan life saves you the most.
Why the Total Cost Feels Higher Than the APR Suggests
A common source of confusion is that the total repayment on a short-term high-APR loan looks much higher than the APR alone implies. A $1,000 loan at 275% APR over 10 months has a total repayment of roughly $2,625 — not $2,750 (100% + 275% / 12 × 10) as some borrowers estimate, and not $1,275 (100% + 27.5%) as others expect. The reason is that APR is annualized, and interest accrues on the outstanding balance each month rather than on the original principal. For an amortizing loan, the effective cost depends on both the APR and the term. Longer terms mean lower monthly payments but higher total interest; shorter terms mean higher monthly payments but lower total cost.
Comparing Products with the Same Calculator
The calculator above works for any fixed-payment loan, so you can use it to compare offers side by side. Enter the APR and term for a credit-union PAL (typically 28% over 6–12 months), a 36%-APR bad-credit personal loan, or a MoneyKey installment loan (249%–295%+), and read the "Total Repayment" and "Cost per $1 borrowed" figures. The difference is often dramatic: on a $1,000 loan over 10 months, a 28% PAL costs about $130 in interest, while a 275% MoneyKey installment loan costs about $1,625 in interest. That $1,495 difference is money you would keep if the PAL option is available to you.
Assumptions and Limits
This calculator assumes: level monthly payments, no fees added to the principal, no missed or late payments, no prepayment penalty (correct for MoneyKey), and no changes to the APR over the loan life (correct for fixed-rate installment loans). If a loan has an origination fee, the effective cost is higher than the APR implies — the fee should either be added to the principal or subtracted from the loan proceeds before you enter the amount. Lines of credit (revolving) work differently from installment loans; this calculator does not model minimum-payment revolving accounts, where a low minimum payment can extend repayment for years.
