Smart analysis
Recommendations
Tailored to your live inputs and result—guidance only, not professional advice.
- Compare carefully
Lowest payment isn’t always cheapest
Longer terms cut the monthly bill but usually raise lifetime interest. Use total cost (including fees) as the tie-breaker.

Terms & how it works
Confused by a field? Read the short definitions here while you use the tool.
Loan Amount
The amount you borrowed (or still owe). Interest is charged on this balance.
Annual Interest Rate (%)
APR — the yearly interest rate. We convert it to a monthly rate (APR ÷ 12) inside the math.
Loan Term (months)
How many months the loan is scheduled to run. Longer terms usually mean smaller payments but more total interest.
- M
Monthly payment
Fixed installment covering interest and principal.
- P
Principal
Amount borrowed or remaining balance.
- r
Monthly rate
Annual APR ÷ 12 ÷ 100.
- n
Term (months)
Number of scheduled payments.

How to Calculate Personal Loan Step-by-Step
- 1Enter the amount you plan to borrow.
- 2Provide the expected annual percentage rate (APR).
- 3Choose a repayment term in months.

Governing formula
M = P · r(1+r)^n / ((1+r)^n − 1)
Fixed-rate personal loan amortization from principal, APR, and term.
Example: set Loan Amount ($) = 10,000, Annual Interest Rate (%) = 9.9, Loan Term (months) = 36, then read the result.
Variable definitions

Practical guide
Using the Personal Loan Calculator well
Who this is for
Borrowers estimating payment and total interest before signing a personal loan offer.
Worked example
Compare a $12,000 loan at two APRs and terms to see how a lower rate or shorter term changes monthly payment versus total interest.
Payment comfort vs total cost
Longer terms lower the payment and usually raise total interest. Decide which constraint binds: cashflow or lifetime cost.
Common pitfalls
- Focusing only on monthly payment while stretching term
- Missing origination fees in APR comparisons
