How It Works
This calculator compares two strategies: making voluntary lump-sum repayments to clear your student loan early versus investing that money instead. Early repayment saves interest but only makes financial sense if you would otherwise repay the loan in full. If you are on track for write-off, early repayment is effectively giving money back to the government.
The comparison models both scenarios over the remaining loan term. It calculates the interest saved by early repayment, then compares this to projected investment returns (net of tax) from investing the same lump sum. It accounts for the opportunity cost of money used for repayment.
A key rule of thumb: only consider early repayment if you are confident you will repay the full balance before write-off. If your projected total repayments over 30 years exceed the outstanding balance, early repayment saves money. Otherwise, the money is better invested or used elsewhere.
Example: £30,000 balance, £50,000 salary, considering £5,000 lump sum
- Without lump sum: projected total repayment ≈ £48,000 (clears year 23)
- With £5,000 lump sum now: saves ~£2,800 in interest
- Alternative: invest £5,000 at 5% for 23 years = £15,300
- Better option in this case: invest (net gain ~£12,500 vs £2,800 saving)
