Futures price at inception and how daily settlement changes value
At inception a futures contract is priced like a forward, and both are worth zero. A forward's gain or loss builds up until expiry. A futures contract pays its gain or loss every day through the margin account, so right after each settlement its value is back to zero.

What is the futures price at inception?
The futures price at inception is found the same way as a forward price: no-arbitrage compounding of the spot price at the risk-free rate, adjusted for income and costs of holding the underlying. Nothing is paid to enter, so the contract’s value at inception is zero for both buyer and seller, exactly as for a forward.
Income (dividends, coupons) lowers the price and costs (storage, insurance) raise it. A futures price that sits well below this level may signal a convenience yield from holding the physical asset.
A commodity trades at 8,500.00. The present value of income from holding it is 0.00 and of storage costs is 40.00. The risk-free rate is 4.00%. The no-arbitrage futures price for delivery in 0.5 years is closest to:
(8,500.00 − 0.00 + 40.00) × (1 + 0.04)^0.5 = 8,540.00 × 1.019804 = 8,709.13

For an underlying that is a portfolio (an index) or involves two currencies, the curriculum uses continuous compounding.
What is a forward worth during its life?
The forward price is fixed when the contract is signed. The contract’s forward value changes as the spot price moves: it is the spot price less the present value of the fixed price still to be paid.
Nothing is paid until expiry. A forward that is well in the money for one party is an unpaid claim on the other, which is why forwards carry credit risk and futures do not accumulate it.
How does daily settlement work?
Futures are marked to market every day. The mark to market (MTM) is the change in the contract’s value since the last mark. Under daily settlement the exchange pays that gain from the loser’s margin account to the winner’s, and the contract is re-set to the new settlement price. The payment is called variation margin.
After the payment, the value reset to zero is complete: the contract is worth nothing at the new price, and tomorrow’s value will be only tomorrow’s move. The short’s variation margin is the same amount with the opposite sign.
A trader is long 1 futures contract of 25 units each. The settlement price moves from 8,412.50 to 8,384.00. The day's variation margin credited to (positive) or debited from (negative) the margin account is closest to:

Switch between the two contracts on the same price path. The forward view builds one large unpaid value; the futures view pays daily bars and returns its value to zero each evening, yet the cash paid in total ends close to the forward’s.
- Forward Memorize private OTC contract
- Price F₀(T) is fixed for life
- Value S_t − F₀(T)(1 + r)^−(T−t), builds up
- Cash paid once, at expiry
- Credit exposure grows with the unpaid value

- Futures Memorize standardized, exchange-traded, margined
- Price re-set daily to the settlement price
- Value zero right after each daily settlement
- Cash paid every day, via variation margin
- Credit exposure limited to one day of moves

Exam tip Price and value are different things. A futures price changes daily; a futures value is zero after each settlement.
Do the total gains differ?
The cumulative MTM gain or loss over the whole life is approximately the same for a futures contract and a comparable forward. The contracts differ in when the cash moves, not in how much moves in total.
Go deeper Why the two totals are not exactly equal
Futures gains and losses arrive during the life and earn or cost interest, while the forward’s value is a single present value. The last lesson in this module shows how the sign of that interest effect depends on whether the futures price moves with interest rates.
Go deeper Credit consequences
A forward can carry a large unpaid exposure to the counterparty, which is why over-the-counter (OTC) dealers often ask for collateral. A futures position cannot: the clearing house settles each day, so the most that can be unpaid is one day’s move, and a missed margin call closes the position out.
Memorize this
MemorizeForward versus futures: price and value
| Forward | Futures | |
|---|---|---|
| Value at inception | 0 | 0 |
| Price during life | never changes | new settlement price each day |
| Value during life | 0 after daily settlement | |
| Gain or loss paid | once, at expiry | every day (variation margin) |
| Total gain or loss | about the same, paid in instalments |
Memory hook Inception: same price, both zero. After that, "futures reset, forwards accumulate".
Know it cold Futures value right after settlement = 0. Variation margin = (new settlement price − old) × size × contracts; sign flips for a short. At expiry the futures price converges to spot.

How it is asked
-
Value after daily settlement
Immediately after settlement, the value of a long futures position is…
Zero. Trap: the cumulative gain, or S − PV(f₀) (the forward formula).
-
Day's variation margin
Long 3 contracts of 100 units, settlement price 52.40 → 51.90.
(51.90 − 52.40) × 100 × 3 = −150. Traps: one contract only, wrong sign.
-
Which contract carries the large unpaid MTM
Mid-life, which of forward and futures can hold a large accumulated value?
The forward. The futures value is reset to zero each day.
-
Price at inception with carry
Spot 1,800, PV of storage 15, r = 3%, T = 0.25.
(1,800 + 15) × 1.03^0.25 = 1,828.46. Trap: ignoring the storage cost (1,813.35).
Exam traps
- Using S_t − PV(f₀) as the futures value mid-life. That is the forward formula; a futures value is zero after settlement.
- Saying forward and futures prices differ at inception when rates are constant. They are the same.
- Forgetting that total gain or loss over the life is about the same for both contracts. Only the timing differs.
- Mixing up price and value. The futures price changes every day; its value is reset to zero.
- Getting the sign wrong for the short. A rising settlement price is a loss for the short.
Checkpoint
6 exam-style questions. About 90 seconds each.
1Immediately after the daily settlement, the value of a long futures position is:
2A trader is long two soybean futures contracts of 5,000 bushels each. The settlement price moves from USD 11.84 to USD 11.69 a bushel. The day's variation margin is closest to:
3A metal trades at EUR 2,000 with a risk-free rate of 3%. It has no storage costs or income. The one-year futures price is closest to:
4Halfway through the life of otherwise identical contracts, which one most likely carries a large accumulated value that has not yet been paid?
5A forward was agreed at 940. With four months to expiry the spot price is 962 and the risk-free rate is 3%. The value of the long forward per unit is closest to:
6A trader is short 4 futures contracts of 50 units each. The settlement price rises from 318.60 to 320.15. The day's variation margin is closest to:
Key takeaways
- At inception the futures price equals the forward price and both contracts are worth zero.
- A forward's value builds up and is paid at expiry; a futures contract is settled daily and its value resets to zero.
- Daily variation margin = (new settlement price − previous) × size × contracts, with the sign reversed for the short.
- The total gain or loss over the life is about the same for both; only the timing differs.

Questions candidates ask
What is the difference between futures price and futures value?
The price is the level the contract trades at and is re-set every day to the settlement price. The value is what the position is worth to its holder. Right after daily settlement the value is zero, because the day's gain or loss has just been paid in cash.
Why is a futures contract's value zero after daily settlement?
The exchange credits or debits the gain or loss to the margin account each day and re-sets the contract to the new settlement price. A new contract at the market price is worth nothing, so the value starts again at zero. A forward is not settled, so its value accumulates.
Are futures prices the same as forward prices?
At inception, yes: both equal the spot price compounded at the risk-free rate, adjusted for income and costs. Later their cash flows differ, and the last lesson in this module explains why the two prices can drift apart slightly.
