> The prorated rent calculator works out the rent due for a partial month when you move in or out mid-month, by the daily rate based on the days in that month (or a 30- or 365-day year).

## Inputs

- Moving in or out?
- Moving date
- Basic monthly rent
- Method

## Results

- Days in the month
- Days charged
- Daily rent
- Prorated rent

## Formula

```
Daily rent = monthly rent ÷ days in the month (or × 12 ÷ 365, or ÷ 30)
Moving in: prorated rent = daily rent × days from move-in to month end (inclusive)
Moving out: daily rent × days from the 1st to move-out (inclusive)
```

## Explanation

Landlords use different methods: days in the actual month, a 30-day "banker's month" or an annual daily rate. The difference is usually small, but check your lease.

### How to use the Prorated Rent Calculator

- **Moving in or out?**
- **Moving date**
- **Basic monthly rent**
- **Method**

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

### How it works

Choose whether you are moving in or out, the date and the monthly rent, and the method.

### Tips

- Get a written loan estimate and compare the APR, not just the interest rate.
- Include property tax, insurance, HOA fees and maintenance in your monthly budget.
- A larger down payment lowers the payment and can remove mortgage insurance.
- Rates change daily – use a current quote for the most accurate result.

### Common mistakes to avoid

- Looking only at the monthly payment instead of the total cost of the loan.
- Forgetting closing costs and fees.
- Assuming home prices always rise.
