Common questions
What others asks before signing up?
Should I refinance my home loan?
If you can secure a lower interest rate, refinancing may save you hundreds per month and tens of thousands over the life of your loan. This calculator gives you an estimate of potential savings — a mortgage broker will confirm exact figures after reviewing your full situation.
How much can I save by refinancing?
Savings depend on your current rate, the new rate, your loan balance and remaining term. On a $500,000 loan, a 0.50% rate reduction could save around $160 per month. Use the calculator above for an estimate based on your numbers.
What are the costs of refinancing?
Typical costs include a discharge fee from your current lender ($300–$400) and an establishment or application fee from your new lender ($0–$600). Some lenders waive application fees or offer cashback of $2,000–$4,000 to offset switching costs.
How accurate is this refinance savings calculator?
The calculator uses standard amortisation formulas to produce an estimate. Actual savings depend on exact loan terms, fees, features and lender criteria. A mortgage broker will confirm the numbers after reviewing your circumstances.
Can I add this calculator to my WordPress, Webflow, Squarespace, Wix or Shopify site?
Yes. Copy a single embed code from your Leadkit dashboard and paste it into any page. The calculator inherits your brokerage branding and feeds leads straight into your pipeline.
What do I get when someone fills out the calculator?
You receive an instant email notification with the borrower's contact details, current rate, target rate, loan balance and estimated savings — everything you need to start the refinance conversation.
What if I don't have a website?
Leadkit auto-generates a branded quote page for your calculator at a unique URL you can share on social media, in emails or on your Google Business profile.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this refinance savings calculator is calculated
This calculator produces an estimate of potential refinance savings, not a binding commitment. Actual savings depend on exact loan terms, fees and lender criteria.
GST handling: GST does not apply to home loan interest or refinancing fees in Australia.
1
Calculate current repayments
Your current loan balance, interest rate and remaining term are used to calculate your existing monthly repayment using the standard amortisation formula.
M = P × (r × (1+r)^n) / ((1+r)^n − 1)
2
Calculate new repayments
The same formula is applied with the new interest rate to determine what your monthly repayment would be after refinancing.
3
Determine monthly and annual savings
The difference between current and new repayments gives your monthly saving. This is multiplied by 12 for the annual figure and by the remaining term for total interest saved.
4
Calculate break-even timeline
Net switching costs (discharge fee plus establishment fee minus any cashback) are divided by the monthly saving to show how many months until the refinance pays for itself.
