How the numbers work: benefits, ACC and student support
93 worked calculations taken from the guides on this subject, each shown a line at a time with the figure it arrives at.
A calculator gives you an answer. These show the arithmetic behind one, which is what you need when you have to check it, explain it to somebody else, or follow it with your own numbers. Every heading links to the guide that works it through in full, and that guide is where any rate or threshold is kept current.

Student Loan Repayment Guide
Student Loan Basics
- Live in NZ (or overseas <183 days/year)

Annual repayment: $3,705
Self-Employed Repayments

Discounted Payback Period Guide
The Basic Formula
- DPB = Year Before Recovery + (Remaining Amount / Cash Flow in Recovery Year)
Simple Example
- Year 1: $3,000 / (1.10)^1 = $2,727
- Year 2: $3,000 / (1.10)^2 = $2,479
- Year 3: $3,000 / (1.10)^3 = $2,254
- Year 4: $3,000 / (1.10)^4 = $2,049
Simple Example
- Year 0: -$10,000 (initial investment)
- Year 1: -$10,000 + $2,727 = -$7,273
- Year 2: -$7,273 + $2,479 = -$4,794
- Year 3: -$4,794 + $2,254 = -$2,540
- Year 4: -$2,540 + $2,049 = -$491
- Year 5: -$491 + $1,863 = +$1,372 (positive!)
Simple Example
- Recovery occurs in Year 5
- DPB = 4 + ($491 / $1,863)
- DPB = 4 + 0.26
DPB = 4.26 years
Example 1: Equipment Purchase
- Initial cost: $150,000
- Annual cash flows: Year 1: $30,000, Year 2: $35,000, Year 3: $45,000, Year 4: $60,000, Year 5: $85,000
- Discount rate: 10%
Example 1: Equipment Purchase
- Recovery occurs between Year 4 and Year 5
- Amount still to recover at end of Year 4: $19,045
- Cash flow in Year 5: $52,785
- DPB = 4 + ($19,045 / $52,785)
- DPB = 4 + 0.36
DPB = 4.36 years
Example 1: Equipment Purchase
- Initial cost: $250,000
- Annual cash flows: Year 1: $55,000, Year 2: $65,000, Year 3: $77,000, Year 4: $99,000, Year 5: $105,000
- Discount rate: 10%
- DPB = 4 + ($20,871 / $65,205)
- DPB = 4 + 0.32
DPB = 4.32 years

ACC Weekly Compensation
Abatement when you return to work
- Usual pre-injury pay: $1,000 a week
- Full weekly compensation at 80%: $800
- You return part-time and earn: $300 a week
- Abated compensation so total does not exceed usual pay: $1,000 - $300 = $700
You receive $300 wages + $700 ACC = $1,000, not more than your usual pay
🔢 Real-World Examples
- Usual weekly pay: $70,000 ÷ 52 = $1,346.15
- Week 1 (work injury), paid by his employer at 80%: $1,346.15 × 80% = $1,076.92
- From day 8, ACC pays 80%: $1,346.15 × 80% = $1,076.92 a week
$1,076.92 gross a week, above the $766.40 minimum and below the $2,466.20 maximum
🔢 Real-World Examples
- Usual weekly pay: $52,000 ÷ 52 = $1,000.00
- Week 1: no employer payment, so she uses annual leave
- From day 8, ACC pays 80%: $1,000.00 × 80% = $800.00 a week
$800.00 gross a week from ACC, above the $766.40 minimum
🔢 Real-World Examples
- Usual weekly pay: $220,000 ÷ 52 = $4,230.77
- 80% would be: $4,230.77 × 80% = $3,384.62 a week
- But the maximum from 1 July 2026 is $2,466.20 a week
- Capped payment: $2,466.20 a week = $128,242.40 a year
Effective replacement: $128,242.40 ÷ $220,000 = about 58% of his income, not 80%
- Agreed CoverPlus Extra amount: $80,000
- CoverPlus Extra pays 100% of the agreed amount: $80,000 ÷ 52 = $1,538.46 a week
- Compare standard CoverPlus:
- If her last tax return showed $60,000, standard CoverPlus pays 80%
- $60,000 × 80% = $48,000 ÷ 52 = $923.08 a week
CoverPlus Extra: $1,538.46 a week vs standard CoverPlus: $923.08 a week
Benefit Advances and Temporary Additional Support
How much Temporary Additional Support can be
- Net main benefit rate: $400.00 a week, used here as an illustration
- Maximum Temporary Additional Support: $400.00 x 30% = $120.00 a week
Up to $120.00 a week, and none of it repayable.
Why the advance arithmetic goes wrong
- Total advanced: $900.00
- Weekly repayment: $20.00
- Weeks of repayment: $900.00 / $20.00 = 45 weeks
- Income reduction: $20.00 / $400.00 = 5% less each week, for those 45 weeks
Nearly eleven months on 5 percent less, which is itself a reason to need help.
Why the advance arithmetic goes wrong
- Weekly amount: $60.00
- Over 13 weeks: $60.00 x 13 = $780.00
- Repayable: $0.00
$780.00 you keep, against $900.00 you repay over 45 weeks.
Two rules that are worth money
- Make contact first , by phone or through MyMSD, before gathering anything.
- Then complete the application within 20 working days of that contact.
- Assistance can run from the contact date rather than from the day you finished.
Delaying the first call is the expensive part, not delaying the paperwork.
Student Allowance and Student Loan NZ
The 12% Repayment Rule
- Example: Salary of $55,000/year
- Repayment threshold: $24,128
- Amount over threshold: $30,872
- 12% of $30,872 = $3,704.64/year
- Per fortnight: approximately $142.49
How Long Does Repayment Take?
- Typical 3-year degree loan: ~$57,000
- Starting salary: $55,000
- Annual repayment at 12%: $3,705
- Years to repay (no salary increases): ~15 years
- With 3% annual salary increases: ~10 to 12 years
- With $100/month voluntary extra payments: ~8 to 9 years
Example 1: Allowance vs Loan Comparison
- Student A (gets allowance): Fees $21,000 loan + $0 living costs loan = $21,000 total debt
- Student B (no allowance): Fees $21,000 + Living costs $36,600 + Course costs $3,000 = $60,600 total debt
- Difference at graduation: $39,600
- At $55K salary, Student A repays in ~6 years; Student B in ~15 years
Real-World Story: The Smart Non-Repayer
- Compulsory repayments: 12% of ($72K - $24,128) = $5,745/year
- Instead of extra voluntary repayments of $200/month...
- ...invested $200/month into a diversified KiwiSaver growth fund at ~6% return
- After 8 years: KiwiSaver extra = ~$24,000 (plus employer match)
- Student loan still being repaid at 0% interest (free money)
- Net benefit of investing vs extra repayments: approximately $8,000+
NZ Super: Eligibility, Rates and How to Apply
It Is Taxable
- NZ Super is paid fortnightly at the rate for your living situation
- Tax is deducted using the code you provide
- If you have other income, it sits on top of NZ Super
- The combined total can reach a higher tax bracket
- Choosing the correct tax code avoids a year-end surprise
How It Fits With KiwiSaver
- NZ Super gives a steady fortnightly base income for life
- KiwiSaver gives a lump sum you control from age 65
- Together they fund a more comfortable retirement
- Neither reduces the other
How to Apply

- 2. Provide ID, IRD number and bank details
- 3. Confirm your residency history and living situation
- 4. Choose the correct tax code for your total income

NZ Superannuation Guide
NZ Super and KiwiSaver
- NZ Super (couple): ~$850/week net
- KiwiSaver withdrawal ($400,000 over 25 years): ~$307/week
- Combined: ~$1,157/week = ~$60,164/year
- This is a comfortable but not lavish retirement income for a couple
Example 1: NZ Super Plus KiwiSaver
- NZ Super (single, living alone): ~$550/week net
- KiwiSaver drawdown ($280,000 over 25 years at 4% return): ~$280/week
- Total retirement income: ~$830/week = $43,160/year
- This is above the single-person poverty threshold and reasonably comfortable
Example 2: The Overseas Pension Deduction
- NZ Super entitlement (single, living alone): ~$550/week
- UK State Pension: $220/week
- Direct deduction: $220 deducted from NZ Super
- NZ Super payment: $550 - $220 = $330/week
- Total income: $330 (NZ Super) + $220 (UK pension) = $550/week
- John receives the same total as someone without an overseas pension
