Personal Loan Calculator
Price an unsecured instalment loan including the origination fee deducted from proceeds, which pushes the true APR well above the quoted rate.

What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: Personal loans are unsecured, so rates are higher and origination fees are usually deducted from the advance. Borrowing $25,000 at 11.9% over five years costs $554.85 monthly, but a 5% origination fee means you receive $23,750.00 and the true APR is 14.181%.
Formula
Interest is charged on the full amount borrowed while only the net reaches your account, which is exactly why the APR exceeds the quoted rate.
Worked Example
- Payment on the full amount. $25,000 at 11.9% over 60 months = $554.85.
- Deduct the fee. 5% of $25,000 = $1,250.00, so you receive $23,750.00.
- Total the repayments. $554.85 × 60 = $33,290.92.
- Find the true cost. $33,290.92 − $23,750.00 = $9,540.92.
- Solve for APR. The rate matching $23,750.00 to this payment is 14.181%.
Analyst note. The quoted 11.9% understates the cost by 2.281 percentage points because the fee is deducted from proceeds rather than charged separately. If you need $25,000 in hand you must borrow roughly $26,316 at this fee level, which raises the payment again. Always compare personal loan offers on APR, never on the headline rate.
Strengths & Limits Of This Model
Where this engine is strong
- Runs entirely in your browser — no figure you type is transmitted or stored.
- Shows the full working, so every number can be traced and challenged.
- Free, unmetered and free of affiliate incentives.
Where it stops
- Generalised assumptions cannot capture every individual circumstance.
- Jurisdiction-specific rules and mid-year changes may not be reflected.
- A model output is not a substitute for a professional review of your position.
Practical Use Cases
Consolidating credit card debt
Replacing revolving debt at 20% or more with a fixed instalment loan at 14.181% APR is genuine arbitrage, provided the cards are not immediately re-used. Compare a secured alternative with the Home Equity Loan Calculator.
Funding a cost without pledging collateral
Unsecured borrowing puts no asset at risk, which is worth a meaningful rate premium over a second mortgage. Weigh both with the Loan Comparison Calculator.
Comparing lender offers accurately
One lender's 11.9% with 5% origination is worse than another's 13% with none. Only the APR output exposes that, much as the Mortgage APR Calculator does for property loans.
Methodology & Editorial Standards
The payment amortises the full loan amount, because interest is charged on the amount borrowed rather than the amount received. The origination fee is deducted from proceeds, which is standard practice among personal loan providers, so the borrower receives less than the face amount while repaying the whole of it. APR is solved by bisection as the rate at which the net advance amortises to the actual payment, consistent with Regulation Z. Some lenders instead add the fee to the balance or charge no fee at all in exchange for a higher rate; both are modelled by adjusting the fee input. Late fees, insurance add-ons and prepayment penalties are excluded, as is the effect of early repayment, which on a simple interest loan reduces total interest but never recovers the origination fee. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Personal Loan Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is the true cost of a personal loan?
Total repaid less cash received. Here $33,290.92 is repaid against $23,750.00 received, so the true cost is $9,540.92 — considerably more than the $8,290.92 of stated interest.
Why is the APR higher than the interest rate?
Because the 5% origination fee is deducted from proceeds. You pay interest on $25,000 but receive $23,750.00, which lifts the effective rate from 11.9% to 14.181%.
How do I compare personal loan offers?
By APR only. A lender quoting 11.9% with a 5% fee is more expensive than one quoting 13% with none. The headline rate is close to meaningless without the fee.
Should I borrow extra to cover the fee?
If you need $25,000 in hand, you must borrow about $26,316 at a 5% fee. That raises the payment proportionally, so build it into the amount rather than discovering the shortfall at funding.
Is a personal loan better than a credit card?
For a fixed sum repaid over a defined period, almost always. Fixed rates and a definite end date beat revolving debt at 20% or more, provided the cards are not immediately re-used.
Is a personal loan better than a home equity loan?
It is unsecured, so your home is not at risk, but it costs several points more. The premium buys real protection, and whether that is worth it depends on how certain your income is.
What credit score do I need?
The best rates require 720 or above. Below 660 rates rise steeply and origination fees widen toward the 8% to 10% end of the range, which compounds the APR problem.
Are personal loan rates fixed?
Almost always, which is a genuine advantage. The payment and end date are known from the outset, unlike a credit card or line of credit.
Can I pay off a personal loan early?
Usually without penalty, and doing so saves remaining interest since most are simple-interest loans. The origination fee is never refunded, so early repayment raises the effective APR.
Do all personal loans charge origination fees?
No. Many lenders, particularly credit unions, charge none and price the rate slightly higher instead. Enter zero to model those and compare APRs directly.
How does term length affect cost?
Substantially. Three years at this rate costs $829.16 monthly but only $4,849.91 of interest, against $8,290.92 over five years. Shorter terms cost more per month and far less overall.
Will a personal loan hurt my credit score?
There is a small initial dip from the hard enquiry and new account. Over time, on-time instalment payments help, and consolidating revolving balances usually improves utilisation markedly.
Is this personal loan calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
Which currency does it use?
Amounts display in US$ accounting format, but the underlying mathematics is currency-agnostic. The result is identical in any currency, so simply read the figures in your own.
Why does a result show an em-dash?
An em-dash indicates the calculation is not defined for the inputs given — typically a division by zero or a value outside the valid domain. We show a dash rather than a misleading number.
