> The home improvement loan calculator works out the monthly payment, total interest and total cost of a home improvement or renovation loan from the loan amount, interest rate and term, including the origination fee and the real APR.

## Inputs

- Loan amount
- Interest rate (APR) (%)
- Loan term (years, months)
- Origination fee (% of loan) (%)

## Results

- Monthly payment
- Total interest
- Total of all payments
- Origination fee
- Money you receive
- Real APR including the fee

## Formula

```
Monthly payment = L × i ÷ (1 − (1 + i)^−n), i = APR ÷ 12, n = months
Total interest = payment × n − L
APR with fees: the rate at which (L − fee) equals the present value of the payments
```

## Explanation

Unsecured home improvement loans are personal loans – fast, but with higher rates than a HELOC or home equity loan. Origination fees of 1–8% are taken from the money you receive, which raises the real APR.

### How to use the Home Improvement Loan Calculator

- **Loan amount**
- **Interest rate (APR)**
- **Loan term**
- **Origination fee (% of loan)**

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

### How it works

Enter the loan amount, interest rate and term and the origination fee.

### 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

- **Monthly payment** = pmt([Interest rate (APR)]÷1200, [Loan term], [Loan amount])
- **Total interest** = [Monthly payment]×[Loan term] - [Loan amount]
- **Total of all payments** = [Monthly payment]×[Loan term]
- **Origination fee** = [Loan amount]×[Origination fee (% of loan)]÷100
- **Money you receive** = [Loan amount] - [Origination fee]
- **Real APR including the fee** = rate([Loan term], 0 - [Monthly payment], [Loan amount] - [Origination fee])×1200

### Example values
