Help to Buy Interest Rate Calculator: Complete Guide 2024
The Help to Buy equity loan scheme has helped over 350,000 households purchase their first home since its launch in 2013. However, many buyers don’t fully understand how the interest payments work after the initial 5-year interest-free period. This comprehensive guide explains everything you need to know about Help to Buy interest rates and how to calculate your payments.
How Help to Buy Equity Loan Interest Works
The Help to Buy scheme provides an equity loan of up to 20% (40% in London) of the property value, which is interest-free for the first 5 years. After this period, you’ll need to pay:
- Year 6: 1.75% interest on the loan amount
- Subsequent years: The interest rate increases annually by the Consumer Price Index (CPI) plus 2%
- Monthly payments: Calculated on the outstanding loan amount
For example, if you took a £60,000 equity loan (20% of a £300,000 property), your payments would be:
| Year | Interest Rate | Monthly Payment | Annual Cost |
|---|---|---|---|
| 6 | 1.75% | £87.50 | £1,050 |
| 7 | ~3.95% | £197.50 | £2,370 |
| 8 | ~6.15% | £307.50 | £3,690 |
Key Factors Affecting Your Payments
- Property value changes: Your payments are based on the current market value of your home, not the original purchase price. If your home increases in value, your loan amount (and thus your interest payments) will also increase.
- Inflation rates: The annual interest rate increase is tied to CPI + 2%. With UK inflation reaching 11.1% in October 2022 (source: Office for National Statistics), many Help to Buy owners saw significant payment increases.
- Repayment strategy: You can make partial repayments (minimum 10% of property value) to reduce your loan amount and future interest payments.
- Loan term: The standard term is 25 years, but you can repay earlier without penalty.
Help to Buy vs. Traditional Mortgage: Cost Comparison
To understand whether Help to Buy is right for you, compare it with a traditional 95% mortgage:
| Help to Buy (20% loan) | 95% Mortgage | |
|---|---|---|
| Property Value | £300,000 | £300,000 |
| Deposit | 5% (£15,000) | 5% (£15,000) |
| Borrowing | £240,000 (80% mortgage + 20% equity loan) | £285,000 (95% mortgage) |
| Year 1-5 Costs | £0 interest on equity loan | Higher mortgage payments |
| Year 6+ Costs | Equity loan interest + mortgage payments | Mortgage payments only |
| Flexibility | Can repay equity loan early | Standard mortgage terms |
Strategies to Minimize Help to Buy Interest Costs
If you’re approaching the end of your interest-free period, consider these options:
- Remortgage to repay the equity loan: Many homeowners remortgage after 5 years to pay off the equity loan and avoid the interest charges. According to MoneyHelper, this is the most popular strategy.
- Make partial repayments: You can repay chunks of your loan (minimum 10% of property value) at any time. This reduces your future interest payments.
- Sell your home: When you sell, you must repay the equity loan as a percentage of the current market value.
- Staircase to ownership: Gradually increase your share in the property by buying out portions of the equity loan.
Common Mistakes to Avoid
- Ignoring the 5-year deadline: Many buyers are caught off guard when interest payments begin in year 6. Set reminders well in advance.
- Not budgeting for rate increases: The interest rate compounds annually with inflation. What starts as £100/month could double in just a few years.
- Forgetting about property valuations: Your payments are based on current property value, not purchase price. Get regular valuations to understand your liability.
- Assuming you can’t remortgage: Even with the equity loan, remortgaging is often possible and can save thousands in interest.

Frequently Asked Questions
When do Help to Buy interest payments start?
Interest payments begin in year 6 of your equity loan. For example, if you bought your home in June 2018, payments would start in June 2023.
How is the annual interest rate increase calculated?
The rate increases each April by the previous September’s CPI inflation rate plus 2%. For example, if September CPI was 10.1%, the new rate would be previous rate + 12.1%.
Can I pay off my Help to Buy loan early?
Yes, you can repay all or part of your equity loan at any time. Partial repayments must be at least 10% of the current property value. This is called “staircasing”.
What happens if I can’t afford the interest payments?
If you’re struggling with payments, contact your equity loan administrator immediately. Options may include extending your mortgage term or switching to interest-only payments temporarily. The government provides guidance through Own Your Home.
Is Help to Buy still available?
The scheme closed to new applications in March 2023, with a final deadline for legal completion by March 2025. Existing Help to Buy homeowners remain on their current terms.
How does selling a Help to Buy property work?
When you sell, you must repay the equity loan as a percentage of the current market value. For example, if you took a 20% loan on a £200,000 property and sell for £250,000, you’d repay £50,000 (20% of £250,000).
Expert Tips for Managing Your Help to Buy Loan
Based on analysis of thousands of Help to Buy cases, here are our top recommendations:
- Start planning in year 4: Begin exploring remortgage options 12-18 months before your interest-free period ends.
- Get regular valuations: Have your property valued every 2-3 years to understand your loan liability.
- Build an emergency fund: Aim to save 3-6 months of interest payments to cover potential rate increases.
- Consider overpayments: Even small overpayments on your mortgage can reduce your loan-to-value ratio, potentially helping you remortgage to repay the equity loan.
- Monitor inflation reports: The Bank of England publishes regular inflation reports that affect your interest rate.
- Use our calculator regularly: Re-run the numbers annually to understand how rate changes affect your payments.
Remember, the Help to Buy scheme was designed to help you get on the property ladder, not to be a long-term financial burden. With proper planning, you can manage the interest payments and eventually own your home outright.
