> The early loan payoff calculator shows how much sooner you'll pay off a loan and how much interest you'll save by adding an extra monthly payment – or the extra needed to pay it off by a target date.

## Inputs

- Loan balance
- Interest rate (%)
- Remaining term (years, months)
- Extra monthly payment
- Target payoff time (months)

## Results

- Current monthly payment
- New payoff time
- Months saved
- Interest without extra payments
- Interest with extra payments
- Interest saved
- Extra payment needed for the target

## Formula

```
Original payment = pmt(i, remaining months, balance)
New payoff time = nper(i, payment + extra, balance)
Extra needed for a target = pmt(i, target months, balance) − payment
```

## Explanation

Before paying a loan off early, check for prepayment penalties and compare the interest rate with what your money could earn elsewhere. High-interest debt is almost always worth paying down first.

### How to use the Early Loan Payoff Calculator

- **Loan balance**
- **Interest rate**
- **Remaining term**
- **Extra monthly payment**
- **Target payoff time**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the loan balance, interest rate, remaining term, the extra payment and an optional target payoff time.

### Tips

- Compare loans by APR and total cost, not just the monthly payment.
- Extra payments go straight to principal and can save a lot of interest.
- Pay off the highest-rate debt first if you want to save the most money.
- Check for prepayment penalties before paying a loan off early.

### Common mistakes to avoid

- Stretching a loan term to lower the payment without seeing the extra interest.
- Paying only the minimum on credit cards.
- Forgetting fees that are rolled into the loan.

### What each result means

- **Current monthly payment** = pmt([Interest rate]÷1200, [Remaining term], [Loan balance])
- **New payoff time** = nper([Interest rate]÷1200, [Current monthly payment] + [Extra monthly payment], [Loan balance])
- **Months saved** = [Remaining term] - [New payoff time]
- **Interest without extra payments** = [Current monthly payment]×[Remaining term] - [Loan balance]
- **Interest with extra payments** = ([Current monthly payment] + [Extra monthly payment])×[New payoff time] - [Loan balance]
- **Interest saved** = [Interest without extra payments] - [Interest with extra payments]
- **Extra payment needed for the target** = max(pmt([Interest rate]÷1200, [Target payoff time], [Loan balance]) - [Current monthly payment], 0)

### Example values

How the main result changes when **Loan balance** changes and everything else stays at the example values above:

## Worked example

Inputs — Loan balance: $25,000; Interest rate: 7.5 %; Remaining term: 5 years; Extra monthly payment: $150; Target payoff time: 36 months.

Results — Current monthly payment = $500.95; New payoff time = 44 months; Months saved = 16; Interest without extra payments = $5,056.92; Interest with extra payments = $3,677.03; **Interest saved = $1,379.89**; Extra payment needed for the target = $276.71.

## FAQ

**Is it smart to pay off a loan early?**
Usually, if there's no prepayment penalty and the rate is higher than your safe savings rate.

**Do extra payments go to principal?**
Tell your lender to apply them to principal, not future payments.

**Which loan should I pay off first?**
The one with the highest interest rate.

**What formula does the Early Loan Payoff Calculator use?**
Original payment = pmt(i, remaining months, balance).
