## Why repayment frequency matters

Your loan interest is calculated daily but charged monthly.  
By paying **more often**, you reduce the **average daily balance** — meaning less interest builds up between payments.

Even though the difference looks small, the savings add up over years.

## Weekly vs fortnightly vs monthly

Here’s how the repayment frequencies compare on a typical Australian home loan:

| Frequency | Payments per year | Main benefit |
|------------|------------------:|---------------|
| **Monthly** | 12 | Standard setup, easiest for budgeting |
| **Fortnightly** | 26 | Slightly faster payoff due to extra half-month each year |
| **Weekly** | 52 | Smallest interest build-up between payments |

If your lender divides the monthly payment exactly (not the annual amount), the difference between fortnightly and monthly is minimal.  
But if they base it on **half the monthly payment × 26 fortnights**, you make the equivalent of one extra month’s repayment per year — shaving months or years off the loan term.

---

## Worked example

Let’s say you borrow **$600,000 at 6.5%** over **30 years**.

| Repayment Type | Approx. Payment | Time Saved | Interest Saved |
|-----------------|----------------:|------------:|----------------:|
| Monthly | $3,792 | — | — |
| Fortnightly | $1,896 × 26 | ~1 year earlier | ~$30,000 less interest |
| Weekly | $948 × 52 | ~1.2 years earlier | ~$33,000 less interest |

Based on equivalent repayment structures where fortnightly/weekly equal half or quarter of the monthly payment.

Dividing the monthly payment in two and paying that amount each fortnight can save $30,000 in interest and reduce the time to repay 
your home loan by 1 year.

---

## Adding small extra payments

This is where the real gains come from.

Adding **$20 per week extra** on the same $600,000 loan:

- Cuts about **1.5 years** off the loan term  
- Saves roughly **$45,000 in interest**  

It’s the same idea as a coffee-a-day — small, automatic, and painless.

> Combine fortnightly payments **plus** a small extra amount for maximum effect.

---

## When more frequent payments make sense

- You’re paid **weekly or fortnightly** (easy to match pay cycle)  
- You prefer small, regular cash outflows instead of big monthly ones  
- You want to **build discipline** and reduce temptation to spend  
- You plan to add regular **extra repayments**

If your income or budget is tight, monthly is fine — just automate a small extra payment instead.

## FAQ

**Does paying weekly always save money?**  
Usually yes, but the amount depends on your lender’s calculation method. If they divide the annual amount into 52 equal payments, the saving is small. If they halve the monthly and multiply by 26 fortnights (or 52 weeks), you make an extra payment each year — which saves more.

**What if I get paid monthly?**  
Stick with monthly, but set up a small extra payment (even $50–$100/month). That can save tens of thousands in interest over the loan’s life.

**Can I switch repayment frequency later?**  
Yes, most lenders allow this online or via app. Always check there are no admin or redraw fees.

**Do extra repayments help more than frequency changes?**  
Yes. Frequency helps modestly; **extra repayments make the biggest impact**.

Loan Repayments: Weekly vs Monthly (What Actually Saves More?)


Buying a home is one of the biggest financial decisions most Australians make.  
Before signing up for a loan, it helps to know what your repayments will look like — and how small tweaks can make a big difference over time.

That’s where a **mortgage repayment calculator** comes in. It lets you estimate your repayments, total interest, and potential savings from extra payments — all before you apply.

## What you’ll need

To get started, gather a few key details:

- **Loan amount** – for example, $650,000  
- **Interest rate** – fixed or variable  
- **Loan term** – typically 25–30 years  
- **Repayment frequency** – weekly, fortnightly, or monthly  
- Optional: **extra repayments** or an **offset balance**

These inputs form the basis for your loan projection.

---

## Step-by-step guide

1. Open the **[Mortgage Calculator](/calculators/mortgage)**.  
2. Enter your loan amount, interest rate, and term.  
3. Choose between **principal & interest** or **interest-only**.  
4. Switch repayment **frequency** to compare how totals change.  
5. Add **extra repayments** to see how much time and interest you can save.

> **Tip:** Paying fortnightly can effectively add one extra month’s worth of repayments each year, helping you pay off the loan faster — without feeling the difference.

---

## Understanding your results

The calculator shows more than just your repayment amount. You’ll see:

- **Repayment amount** – what you’ll pay each period  
- **Total interest** – how much you’ll pay over the life of the loan  
- **Loan end date** – when you’ll be mortgage-free  
- **Amortisation schedule** – how much of each payment goes to principal vs interest  

This breakdown helps you see where your money goes — and how even small extra repayments can save thousands.

---

## Common mistakes to avoid

A calculator gives estimates, not approvals. Avoid these common pitfalls:

- Forgetting to include **fees** or **Lenders Mortgage Insurance (LMI)**  
- Comparing **fixed vs variable** without checking **break costs**  
- Assuming an **introductory rate** lasts for the entire term  

---

## Smart ways to save

Once you understand your baseline, try running a few scenarios:

- Add **$50 extra per week** to see how quickly the term shortens  
- Reduce the **loan term** for faster equity growth  
- Use an **offset account** to lower interest without locking away savings  
- Model a **0.50% rate rise** to test your budget resilience  

> Even small changes — like rounding repayments up to the nearest $10 — can shave years off your mortgage.

---

## The bottom line

A mortgage calculator won’t replace financial advice, but it’s an excellent way to take control.  
It helps you plan, test scenarios, and prepare for different interest rate environments before meeting with a lender or broker.
